Picture this: Snapping photos of our food could be good for us – A study that showed that when people take pictures of what they eat…a more accurate food record (than people’s memory) is obtained and can be analyzed to improve diet! I might try this…do a little self-analysis.

People Are Spotting Rare, Blue-Eyed Cicadas Around Illinois – Most periodic cicadas have red eyes….but this year some have blue! We aren’t hearing cicadas yet at our house even though our area of Missouri is in the range of Brood XIX.  

The people racing to build shelters outside tornado alley – It does seem like there have been more violent storms outside of the traditional tornado alley recently. Even in tornado alley – many houses are built on slab foundations (i.e. no basement) and don’t have storm shelters. My husband was the first to voice the requirement for a basement when we were looking at houses in Missouri…and we ended up buying one with the storm shelter too (in the basement and reenforced).

Relics of a Warmer Past, Some Species May Be Suited to a Hotter Future - By the end of this century, the planet is expected to be approximately as warm as it was 130,000 years ago. Species that arose during this time (like the African grass rat) would be able to withstand a hotter climate. A new model projects that there will be a 39% drop in the number of resident species in tropical lands due to excessive heat.

In a Seismic Shift, U.S. Army Corps of Engineers Elevates Nature-Based Solutions – Finally! Some examples of solutions that are nature based include: Floodplains, Living shorelines, Beaches, Dunes, Wetlands, Reefs, Islands, Green roofs, Tree canopies, Rain gardens, Bioswales, Retention basins, and Permeable and pervious pavements. The upcoming rule issued by the Army Corps is expected to further institutionalize the nature-based future landscape architects have pushed for. But more advocacy will be needed to spread the benefits of designing with nature across all the communities with which the Army Corps engages.

7 Strange Species from the Ocean’s Depths – How many of these have you heard about before? I’d heard of 6 of the 7…the one that was new to me was the Yeti Crab. I didn’t know the Greenland Shark was the same as Ommatokoita though.

Women are 14 times more likely to die in a climate disaster than men. It’s just one way climate change is gendered – And women represent 80% of people displaced by extreme weather. The reasons include women’s pre-existing social and economic disadvantage…and their responsibility for caring for other vulnerable groups, such as children or older people. The author is writing about Australia…but this probably is happening around the world too.

Giant Pandas are returning to D.C.'s National Zoo – Hurray! The new pandas are due before the end of the year and the zoo is upgrading the building and outdoor space now to be ready for their arrival.

Cool Pavements Show Promise as Part of Urban Climate Resilience Strategy – Results from a pilot project in LA that applied a solar-reflective pavement coating, to more than 700,000 square feet of neighborhood streets and another special coatings to basketball courts, parking lots, a school playground, and a colorful community mural by a local artist in July 2022. The study results were published in April 2024: reductions in ambient air temperatures by as much as 3.5°F during extreme heat events and a 25-50 percent reduction in the local census-tract urban heat island index during daytime temperature peaks. The research also indicated notable reductions of up to 10°F or more in surface temperatures following the application of solar reflective pavement coatings, which directly correlated to a reduction in air temperature and felt temperature in the community.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

25 Years, 25 Images – Celebrating twenty-five years since the launch of NASA Earth Observatory (EO) on April 29, 1999 and the EO website with a slideshow!

Insurance Companies: Consider Climate Risk Events As “Constant Threats” - Up until recently, most people weren’t concerned with how their ability to be insured would change — until catastrophic climate disasters began to wreak havoc on communities around the country. I am very glad I don’t own property in Florida or south Texas or California!

New Constitution Gardens (in Washington DC) Will Be a Biodiversity Mecca – Glad there are plans to improve the area. I always enjoyed it even though it was beginning to show its age in the 1990s and early 2000s when we lived in Maryland and visited with our young daughter.

Stunningly Preserved Ancient Roman Glassware Turns Up in a French Burial Site – Found during construction of a new housing development. I am always amazed at how durable a material we normally thing of as ‘breakable’ can be!

Cicada dual emergence brings chaos to the food chain - Cicada emergences can completely rewire a food web. For predators, these emergences are a huge boom in resources. It's basically like an all-you-can-eat buffet for the hungry predator. A study, published in 2023, found the emergence of periodical cicadas changes the diets of entire bird communities. Scientists have found that wild turkeys, for example, will capitalize on the bounty, leading to a wild turkey boom. However, caterpillars, usually preyed on by birds, were left off the dinner menu and their numbers more than doubled. This in turn led to damage to trees caused by out-of-check caterpillar populations. Rising temperatures will lead to periodical cicada emergences starting earlier in the year, experts believe, as well as an increase in unexpected, "oddly-timed" emergences.

Earlier Springs Cause Problems for Birds - As climate change warms our planet, causing spring to arrive weeks earlier than it has historically, birds are struggling to keep up. It’s not just the green vegetation they miss, but the pulse of protein-rich insects many bird species consume on both their breeding grounds and their migratory stop-over points. Birds will still breed but not quite as successfully because food will be more limited. Instead of chicks hatching as insect populations boom, those chicks may catch the end of the insect pulse.

Why you should let insects eat your plants – I skew the additions to my yard toward native plants….and let whatever insects show up enjoy. My community sprays for mosquitos so there probably is some reduction of other insects because of that. But there are enough left to support a barn swallow (and other insect eating birds) flock in our community.

Quantifying U.S. health impacts from gas stoves - Even in bedrooms far from kitchens, concentrations of nitrogen oxide frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off. All the houses I’ve purchased as an adult, have had electric stoves/ovens except one and I only lived there for 3 years. But – in the 1950s and 1960s, my parents had gas stoves/ovens. Back then the houses were not as airtight as they are now so that might have reduced our exposure; my sisters and I never had asthma or other breathing problems, fortunately.

Inside the exquisite Tibetan monasteries salvaged from climate change – Built in the 1300s, the monasteries are impacted by a significant increase in the intensity of storms and rainfall across the region. Increased rainfall saturates the rammed-earth buildings, as moisture in the soil is drawn upward into the walls, leading to issues such as leaking roofs and rising damp. Local people have gained diverse skills, from reinforcing walls to crafting metal statues and restoring paintings. Over the past 20 years, a team of local Lobas trained by Western art conservationists have replaced the old, leaky roofs of the temples with round timbers, river stones, and local clay for waterproofing, and have restored the wall paintings, statues, sculpted pillars and the ceiling decorations, giving these centuries-old monuments a new life.

Possible Conch Shell Communication in Chaco Canyon Explored - The settlements of Chaco Canyon that spread around each sandstone great house fit into the sphere of sound produced by conch shell trumpet blasts; perhaps the settlements were designed to ensure that every resident could hear the notifications.

Floating Solar Array Is Designed to Take the Rough Stuff - Rich opportunities for solar co-location with offshore wind. By combining floating solar with offshore wind farms and thereby leveraging the same energy infrastructure and export cables, the resulting energy production capacity per used area could be drastically improved. Prototype has been developed…should be in the water by June 2024.

Lessons In Rewilding the Scottish Highlands – Working with nature…increasing biodiversity…reducing monoculture.

Five Shocking Animal Hybrids That Truly Exist in Nature, From Narlugas to Grolar Bears to Coywolves – I’ve heard about a few of these…the pictures were interesting.

Pregnancy advances your ‘biological’ age — but giving birth turns it back - Brewing a baby leads to changes in the distribution of certain chemical markers on a pregnant person’s DNA — changes similar to those that are a hallmark of getting older. But new research shows that, several months after a person gives birth, the chemical patterns revert to an earlier state.

Did You Know Sandhill Cranes Dye Their Feathers? – The birds rub iron rich mud onto their feathers…staining them. And some trivia about sandhill cranes at the Platte River (Nebraska) in the early spring:

  • The birds find a lot of waste corn in farm fields, as well as small invertebrates in marshes near the river. A crane can add 20 percent to its weight during two or three weeks in the area.

  • At night, the cranes move to the Platte River for safe roosting in the shallow water.

  • Sandhill cranes are the most numerous of the world’s crane species.

  • In the Central Flyway, more than 500,000 cranes – more than 80 percent of their population.

The heat index -- how hot it really feels -- is rising faster than temperature - Researchers looked at Texas's summer 2023 heat wave and found that the 3 degree F rise in global temperatures has increased the state's heat index as much as 11 degrees F on the hottest days! Arizona's most populous county, covering most of Phoenix, reported that heat-associated deaths last year were 50% higher than in 2022, rising from 425 in 2022 to 645 in 2023. Two-thirds of Maricopa County's heat-related deaths in 2023 were of people 50 years or older, and 71% occurred on days when the National Weather Service had issued an excessive heat warning. With climate change, the relative humidity remains about constant as the temperature increases, which reduces the effectiveness of sweating to cool the body.

158 Cherry Blossom Trees Will Be Cut Down in D.C. in Effort to Withstand Sea-Level Rise – Part of the project to reconstruct a seawall around the Tidal Basin.

Landscape Architecture Strategies Reduce Impacts of Dangerous Extreme Heat – And these apply to what we do in our yard too!

  • Increase tree percentage in parks and green spaces

  • Provide shade on sites

  • Use plant materials and water instead of hardscape

  • Switch to green ground cover, including grasses and shrubs

Plastics Contain Thousands More Chemicals Than Thought, and Most Are Unregulated – Scary! The report also highlights 15 chemical priority groups of concern. These include phthalates, which are used to make plastics more durable and have been found to affect the reproductive systems of animals, as well as per- and polyfluoroalkyl substances (PFAS), which break down very slowly over time and have been linked to health issues including reproductive and developmental problems and increased cancer risk.

Only seven nations meet WHO air pollution standards – The US is not one of the seven: Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand. Bangladesh, Pakistan, India, Tajikistan and Burkina Faso were the top five most polluted countries in 2023 with PM2.5 levels nine to 15 times higher than the WHO's standard. Columbus, Ohio, was the most polluted major city in the United States, while Las Vegas was the cleanest and Beloit, Wisconsin polluted U.S. city overall.

Old Dominion in 1916

/

I enjoyed finding familiar scenes in Walter Hale’s drawings of sights in Virginia, Maryland and the District of Columbia in the book We Discover the Old Dominion that was published in 1916. The text was written by his wife, Louise Closser Hale who was an American actress, playwright, and novelist.

The three sample images I picked from the book are places I have been in recent years. It was interesting to see how they looked in the time before World War I!

The first image is South Mountain (in Maryland). It’s now a rest stop on I-70; in 1916 there was a toll house there and the road was much more rustic.

The second is the Potomac at Harper’s Ferry – still a scenic spot today and part of the Harpers Ferry National Historical Park.

The third is the White House. It looks very similar today --- although there are barricades and fences that weren’t in place in 1916.

Several other Hale books are available on Internet Archive as well: A Motor Car Divorce from 1906, Motor Journeys in 1912, and We discover New England from 1915. The vision of the couple traveling together and creating a book as a product of their experience is appealing – and provide of historical view of the places they saw. Walter Hale died in 1917. Louise Closser Hale continued writing (but not travel books) and went to Hollywood – portraying older women in movies until her death in 1933.

Anna Scripps Whitcomb Conservatory Grounds and Aquarium

/

Continuing from yesterday’s post about our visit to Belle Island, Detroit, Michigan….

The conservatory has a koi pond that had some large specimens that seemed particularly dense near the waterfall. I liked the turtle fountain…reminded me of similar ones at Longwood Gardens in Pennsylvania. I wondered what happened to the koi pond during the winter. Detroit must get very cold.

The structure of the conservatory has some high portions and there are some plants that have grown very tall…filling the spaces.

The grounds are grassy areas with some flower beds that were beginning to fade. I took a few macro images

There was a black squirrel that zipped across the very wet grass (we dodged the soggiest areas). There were black squirrels in London, Ontario too – more than the gray/brown ones.

The grounds also included a Japanese lantern and tower.

We went into the Aquarium. It reminded me of the

Washington DC aquarium that was in the Department of Commerce building; it closed in 2013 but I remembered touring it when I was pregnant with my daughter back in 1989…and becoming very queasy from the fish smell.  The aquarium in Washington DC was completed in 1932. The one on Belle Island has been operational since 1904! They used the lull during the pandemic for renovation…it seemed to be in great shape (and no fishy smells). The lighting was such that it was easier to get reasonably good pictures through the glass! I particularly enjoyed the puffer fish, brittle stars, sea horses, and anemones.

Overall – our visit to Belle Island took about 2 hours. We headed back into Detroit to find a restaurant before we continued our journey to London, Ontario.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

We asked children how they experienced poverty. Here are 6 changed needed now – This was a study done in Australia. I wonder how applicable these findings are around the world.

The identical twins who discovered their secret sibling – An adoption agency that separated twins for adoption in the 1960s…and the researchers that were part of that process. Fast forward to 2022.

Heat wave reveals 17th-century English gardens – Longleat Gardens….a whisper of the past…from before the transition to natural parkland in the 18th century.

Is this the end of DC’s most-beloved hidden landmark? – I’ve never seen (or known about) the Capitol stones in Rock Creek Park but I’ve noticed the old columns dating from the same period that are in the National Arboretum. They are certainly a landmark!

Painted Bunting: The Fun of Local Bird Quests – I remember seeing some painted buntings at a Florida National Wildlife refuge and an indigo bunting under my bird feeder in Maryland. They are special birds!

Colorful solar panels could make the technology more attractive – Color is a lower priority than efficiency for me, but it could be very important in some applications.

A Beginner’s Guide to Butterfly Watching – I wish there were more butterflies to watch! It seems like every year there are fewer of them around.

Taming Tomorrow’s Wildfires – There is a wildfire burning somewhere in the US all the time recently. It’s important that we make changes to reduce their devastation.

New drug candidate fights off more than 300 drug-resistant bacteria – Antibiotics have been around for my whole life…but there is always the discomfort that more bacteria are becoming resistant…and there could come a time that the pre-antibiotic killers will beginning killing people again. I’m glad there are new drugs in development to take up the fight.

Olmec contortionist Reliefs Uncovered in Mexico – Artifacts from a civilization known for colossal head sculptures….hints of their culture.

Country Life (magazine) in 1918

/

The two volumes of Country Life Magazine from 1918 (V34 and V35) include articles about World War I as it was ending. The illustrations are in color and worth a look --- a window into the way people were thinking about the war just as it was ending…before the passing of time made it into history.

There are also photographs. The one of the US Capitol at night with a reflection of the dome is appealing; photography has always been a technology that can be art as well as utility.   

The other articles in the magazines depict life continuing in relatively ‘normal’ fashion for wealthy people of the time.

It was a very different time than we find ourselves a little over 100 years later although there are similarities too. The 1918 flu was continuing and would eventually kill more people than the war; there were few effective treatments and no vaccine as we have for COVID-19. The capitol in 1918 was not a place a crowd of people would attack although there was a frenzy in the country with social change (increasing industrialization and a migration of population to the cities, electricity becoming more widespread, etc.) that led to the roaring 20s and then the crash into the Great Depression of the 1930s.

The subtle influence of the moon on Earth’s weather – Tides….and a lot of complex interactions associated with them. High tide flooding will increase as the climate changes for example.

So much ice is melting that Earth’s crust is moving – When the weight of ice is removed, the land lifts upward…but new measurements show that it moves horizontally as well.

Top 25 birds of the week: Spiderhunters and Sunbirds! – Lots of colorful feathers in this group!

Pecan-enriched diet shown to reduce cholesterol – 470 calories per day is a lot of pecans more than ½ cup. I like pecans but will generally stick to about ¼ cup at a time…may skew toward eating pecans over other nuts although walnuts are a healthy choice as well.

California Drought Hits World’s Top Almond Producer – And maybe almonds are a nut that will be increasing in price…maybe driving people away from almond milk. I’ve already made my switch to lactose free milk.

Northern paper wasps recognize each others faces – Each face is unique!

Giant clams have a growth spurt – thanks to pollution – Evidently modern clams grow faster than ancient ones because of nitrates in the water. It doesn’t necessarily mean that are healthy…just that they are growing faster.

Photography In The National Parks: Fun Fact Photography, Part 2 – The post not only includes ‘fun facts’ about the National Parks – it also explains how the images were captured!

What happens to your brain when you give up sugar – A well timed article for me --- I am dramatically reducing refined sugars and artificial sweeteners in my diet (i.e., I still eat foods that are sweet like bananas).  I thought the headaches that occurred in the first week of my new diet were the simultaneous reduction in caffeine but maybe they were also caused by the sugar reduction.

Watch a bolt of lightning strike the Washington Monument – The monument is on a hill and the tallest thing around…..a conduit to the ground for lightning.

The 'Zoom Boom' Can't Save the Midwest – People are leaving dense, high-cost urban metro areas…but very few of them are going to the heartland.  Maybe some of the areas will benefit from migration because of climate change. Or maybe the Midwest should simply focus on investments to help their economies and create places people want to live….do the groundwork to encourage people to move to the region.

Poison Mushrooms: How to Tell – From the Natural History Society of Maryland…good pictures.

The Avenues of America – An overview picture of Washington DC taken from the International Space Station.

The Invasion Of The National Park System – Quagga mussels, Burmese pythons, feral swine, household pets gone wild, tamarisk trees….and those are just the ones pictured!

Incredible Footage of Iceland’s Fagradalsfjall Volcano – And there are people in many of the pictures to provide scale!

Major advance in fabrication of low-cost solar cells also locks up greenhouse gases – There are so many articles about technologies that sound promising toward creating faster pathways away from fossil fuels….hope a lot of them move forward.

Elephant Trunks Can Suck Water at 330 Miles Per Hour – Wow

Pyramid made of dirt is world’s oldest known war memorial – Located in Syria…and at least 30 people – male and presumed to be warriors – buried in horizontal steps.

COVID-19 pandemic has been linked with six unhealthy eating behaviors -- ScienceDaily – Eating disorders are one of the deadliest psychiatric health concerns and 6 of them have a correlation to the pandemic: mindless eating and snacking, increased food consumption, generalized decrease in appetite or dietary intake, eating to cope, pandemic related reductions in dietary intake, and re-emergence or marked increase in eating disorders.

How flooded coal mines could heat homes – Evidently the water in the mines could be tapped as a source of geothermal heating/cooling!

Kenilworth Park & Aquatic Gardens – 3

/

Continuing the posts about our hike at Kenilworth Park & Aquatic Gardens in Washington DC…today the topic is everything I noticed other than the lotuses and dragonflies.

I looked for a shelf fungus on one the trees near the entrance that I’d seen over several years. It was gone but there was some pancake looking fungus patches on one of the high branches!

2021 06 IMG_4745 (1).jpg

There were other flowers blooming:

2021 06 IMG_4745 (2).jpg

Pickerel Weed. In past years it attracted tiger swallowtail butterflies. I didn’t see any in the gardens this year.

Hibiscus. Not as many as in previous years. This one was growing at the edge of one of the ponds.

2021 06 IMG_4745 (4).jpg

Water lilies. There were none of the giant lily pads that have been at Kenilworth in previous years and some of the ponds usually filled with water lilies were open water…but there were enough for  a few pictures.

Button bush. Again – not as many as I remembered. I wondered what happened to them since it seems like they would be durable along the pond edges from year to year.

2021 06 IMG_4745 (13).jpg

Trumpet vine. A robust native. My mother planted one in the 1960s in a corner of our back yard and then battled it with pruners to keep it from deconstructing the fence.

We walked on the boardwalk out to the mash and river. I was hoping to see herons but didn’t spot any.

At the very end there was a tree with lots of seeds growing in the loop of the boardwalk. It looks like a tree of heaven….a non-native and very invasive. I was surprised that it had not been cut down.

It was getting hotter, and we headed back through the gardens to the car. I was glad I had some cold water to drink on the drive home!

Kenilworth Park & Aquatic Gardens – 2

/

Continuing the posts about our hike at Kenilworth Park & Aquatic Gardens in Washington DC…today the topic is dragonflies.

I tried to photograph the insects from different perspectives than my usual…for interest rather than identification. The very last picture I took is an example; I can’t identify the species but the pictures is interesting because it appears that one of the hind wings is broken. The insect flew to the twig just before I photographed it!

2021 06 IMG_4752 (13).jpg

All my identifications are tentative. I’m not an expert but I try to group the photos that look to be the same species together.

There were lots of Blue Dashers in different positions.

I got both male and female Common Whitetail Skimmer.

There were Slaty Skimmers.

And a Widow Skimmer.

Note – The sites I used for identification are: Insect Identification (Maryland) and out DNR’s Common Dragonflies of Maryland. I enjoyed comparing the species I saw at Howard County Conservancy a few weeks ago with the ones I saw at Kenilworth:

Blue Dasher (Kenilworth)

Common whitetail skimmer (both)

Eastern pondhawk (Howard County Conservancy Mt Pleasant)

Ebony jewelwing (Howard Country Conservancy)

Slaty Skimmer (Kenilworth)

Window skimmer (both)

Kenilworth Park & Aquatic Gardens – 1

/

Late June is the time the lotuses bloom at Kenilworth Park & Aquatic Gardens in Washington DC. We made the trek to the park last week. The pandemic has impacted the gardens somewhat; not all the ponds are full of aquatic plants, and some seemed to be damaged (i.e. plants are round the edge but open water in the center); the facilities are closed but there are porta potties. We took a small ice chest with extra water in the car. We went on a weekday to avoid crowds and arrived shortly before 9. There was a summer camp group organizing near the entrance…a few photographers and mothers with young children in strollers in the garden.

There were still a lot of flowers to enjoy. It seemed like the best ones were further back in the gardens and I enjoyed photographing them.

There are other things to see at Kenilworth while the lotuses are blooming. I’ll post about the dragonflies tomorrow….and the other flowering plants the day after.

Eating processed meat could increase dementia risk, researchers say -- ScienceDaily – A study with a large cohort (500,000 people) in the UK.

Photographer Travels Asia Capturing Beautiful Repeating Patterns – I liked the photographs for the repeating patterns but also how they capture the people and places. The photos capture the cultural landscape.

Stalking The Carnivorous Plants Of Big Thicket National Preserve – I can remember first reading about carnivorous plants in elementary school. I still find them fascinating.

How birds defend against brood parasites – I’ve already seen a pair of cowbirds at my feeder this spring; fortunately, they must have been migrating because I haven’t seen them again.

The Butterfly of Spring: Meet the Mourning Cloak – I haven’t seen one this spring…although I have in other years. All the ones I’ve seen in early spring are more battered that the one in the first picture!

Vitamin A for Nerve Cells – Another reason to eat those orange fruits and veggies. My favorites are carrots and butternut squash!

Washington’s Famed Tidal Basin and Cherry Trees Face Rising Waters – Planning initiated for how the area and its cherry trees could survive the rising waters in the coming decades. Some trees have already been lost.

Cherry Blossoms

/

While our plum tree is the first tree in our yard to bloom, the cherry is not far behind. There is a time when they are both blooming. The cherry blossoms are lighter pink and larger…in the foreground in the picture below with the cherry in the background.

2021 04 IMG_4157 (1).jpg

Early in the month I did some experimental pictures of the cherry blossoms – high key, dark background, and blurry green. I like the high key version to see the details of the flowers and the subtle color…pink buds, tinge of pink in the flowers, the star in the center, the green leaves.

We had a hard frost after the tree started to bloom and then some very breezy days. I noticed that the petals were whirling away from the flowers earlier than I thought they would. It was sunny enough to photograph the flowers even with the breeze moving them around (particularly if I zoom rather than trying to get close)!

We won’t be going down to see the cherry trees in Washington DC as we have in previous years; the pandemic has made it too difficult. The trees around the Tidal Basin generally bloom earlier than our tree. I’ve been reading articles about the flooding around the Tidal Basin trending up in recent years…killing some of the trees, flooding/damaging walkways. It’s sad to think about changes like that.

I am choosing to enjoy the cherry tree in my front yard….its blooms are always part of my celebration of spring.  

The White House in 1940

/
14 21 01 (7).jpg

As I watched the Inauguration, I remembered an old magazine I’d browsed through recently on Internet Archive – the July 1940 edition of House & Garden that included an article about the White House as it was in 1940…and some history of the White House up to that point. I clipped some of my favorite images (click to get an enlarged version of the image).

Much has happened to the building in the intervening 80 years. The White House is still the architectural symbol of the Executive Branch and home of the President for his term. I hope that President and Dr. Biden quickly acclimate to the place…make it into their home…and forge ahead in their roles for the country from its rooms.

The article also included images of some of the other building of Washington DC. Some things have changed since 1940…some not.

I am relieved that the we have a new President as I write this….that we have survived the insurrection at the US Capitol on January 6th and anticipating a positive path forward. Amanda Gorman, the youth poet laureate, was the highlight of the event with her “The Hill We Climb” at the Biden inauguration! And now the work begins for the new administration….

Lincoln Memorial

/

Internet Archive has the June 1923 volume of The Architectural Record – which has pictures of the Lincoln Memorial when it was relatively new, since it opened on May 30th, 1922. Note the small size of vegetation and open area around the monument. The area has changed in almost 100 years! Enjoy the pictures! (Note: In the first group of pictures, click on individual photos to see larger versions…the last one is the wall with the Gettysburg address.)

Jumping to 2020 - The Trust for the National Mall site has a live view of the monument from the top of the Washington Monument…looking down to the World War II Memorial and the reflecting pool toward the Lincoln Memorial and the Potomac / Tidal Basic. The area is a mix of vegetation, water, and monuments…with traffic of Washington DC on all sides. The area is an oasis from dense buildings but still embedded in the city. In the springtime, the cherry trees bloom in the area.

My husband and I are looking forward to being able to see the monuments again – post-pandemic. These pictures from 1923 are so detailed….I want to spend time photographing the monument again….and the other monuments that are nearby – Jefferson, Martin Luther King Jr., Vietnam Vets, Korean Vets, and the Washington monument.

When we are in the streams with high school students, we often find small fish but since they aren’t what we are looking for – we simply put them back without identification. Maybe I should look for a simple small fish ID to take a long and start to photograph them too.

Kenilworth Park and Aquatic Gardens – June 2019

/

The plants that are the main attractions during  the June and July at Kenilworth Park and Aquatic Gardens are the lotuses and the water lilies.

The lotuses were in full bloom in the later part of June when we visited but there weren’t many seed pods yet.

I also found a rolled-up lotus leaf that was interesting. The leaves are round, balancing on a central stem but they start out as a scroll like structure that unfolds. This one was still tightly coiled. I might use it as a prompt to create a Zentangle pattern.

 The water lilies did not seem as dense as they have in previous years and I wondered if the rains and cool temperatures earlier this summer impacted the water lily development.

The button bush was beginning to bloom; I didn’t notice any seed pods yet. There is a ways to go before all the flowers are pollinated…lots of bee activity.

Two trees stood out:

There was a group of developing pine codes high up in a pine near the entrance and

Some shelf fungus growing around a knot (maybe where a branch had been). It looks a little like a bear face to me. I’d noticed it last year too. The shelf fungus look more cracked this year but they still have the orange underneath.

I heard green frogs and searched the shallows from where the sound seemed to emanate….but never  saw the frog.

A pearl crescent butterfly opened its wings as it sat in the grassy path and paused long enough for me to get a picture.

We saw two different kinds of turtles (identified with the help of a reference from Maryland Department of Natural Resources): a small red-eared slider (not native to our area but invading) and

A large northern red-bellied cooter – which is native to our area. It was a large specimen. I wondered how long it had taken to get that big…about 12 inches.

Both ponds had a lot of algae and muck so the turtle shells looked grubby but the heads were vey distinctive…enough for the identification.

Overall – the field trip to Kenilworth was worthwhile and very enjoyable. We went in the morning before the day got too hot.

Dragonflies at Kenilworth Aquatic Gardens

/

The lotuses and water lilies are blooming at Kenilworth Park and Aquatic Gardens from late June into July. The wetlands are attractive to dragonflies too; I saw 5 different kinds when I went on a late June weekend. I found a good reference to help me identify them from Maryland’s Department of Natural Resources.

The first one we saw – and the most numerous – were the blue dashers. They like to perch on the vegetation in the lotus and water lily ponds.

Along the boardwalk out into the Anacostia River wetlands, there were quiet a few autumn meadowhawks. They weren’t as good about staying put for a picture as the blue dashers.

Also on the boardwalk, there was a common whitetail with black bands on its wings.

There was a green eastern pondhawk on a sunny spot of the boardwalk as we were walking back along the boardwalk.

It wasn’t until I got home as was looking at my pictures that I realized I had photographed another type of dragonfly among the lotuses: a common baskettail. It was a pleasant surprise!

Tomorrow I’ll post the other images from our walk around Kenilworth Gardens.

US National Arboretum in Early Spring

/

Last weekend we went to the US National Arboretum to see cherry blossoms. We entered the New York Avenue Gate and parked in the big lot just inside….with cherry trees in sight. We walked over to the trees. I got side tracked by some golden moss with spore capsules…had to take pictures from overhead and then from ground level. It was growing under the cherry trees.

The days before we went had been windy and I found some blooms on the ground – little jewels in the dried leaves and moss.

I zoomed to get some close-up pictures of flowers on the trees – all shades of pink to white.

As I took some pictures of the high branches of one tree, I noticed a lot of bees. I was photographing hand held so had to be content with just knowing the dots in the pictures were insects!

We got back in the car and continued further into the arboretum. There were a lot of cars parking along the side of the road and we could see trees that were blooming ahead. We thought maybe it was more cherry trees. But no – it was deciduous magnolias! They were probably at their peak and gorgeous. People where photographing young children under the trees and held up next to the flowers. There were several different kinds of deciduous magnolias in bloom. My favorites were the deepest pink ones that I saw at the very beginning.

I zoomed in on two buds. Note that the outer covering is very fuzzy. Then there is a covering that looks like brown paper….and then the petals.

Evergreen (southern) magnolias are in the grove as well. They will be beautiful this summer. Right now, the empty pods from last summer are dried (on the tree or the ground under it) – and a study of complexity. I didn’t see a single red seed that had survived the winter in a pod!
