J. Walter Fewkes eBooks

/

I browsed the books by Jesse Walter Fewkes available on Internet Archive recently. His work in the late 1800s - early 1900s is an early record of the archeology and anthropology in the American Southwest. He was one of the first to advocate for government preservation of the ancient sites. I’ve chosen three of his books to feature in this post.

Designs on Prehistoric Hopi Pottery (1919) – When I browse books like this, I am always gleaning ideas for Zentangle tiles. This one also brought back memories of participating in Camp Fire Girls when I was growing up; they included native symbols and geometric designs as part of the program which I enjoyed; it made the arts/crafts were appealing someone like me that was disappointed in any attempts at realistic drawing.

Hopi Katcinas Drawn by Native Artists (1904) – I wonder if Fewkes was one of the first to encourage these artists to document their own culture…emphasizing the aspects that were most important to them rather than using other artists from outside the culture or photographs that might be realistic but subtly emphasizing the aspects important from their own cultural perspective.

Tusayan Katcinas and Snake Ceremonies (1897) – The close of the katcina mask shows how elaborate they could be.

The views of the Altar of the Antelope Priests in 3 different locations were interesting. It’s an opportunity to see  similarities and differences…wondering if it was difference in the progress of the ceremony or variance due to location that caused the altars to look different. Are the parts that are the same the most important?

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.

Oyster Hatcheries Help the Industry Adapt to Climate Change – There are lots of aspects of climate change that impact oysters – making mitigation more complex. The industry is trying to be proactive as problems are recognized.

Could COVID-19 still be affecting us in decades to come? – A summary of some research particularly about brain function/Parkinsons and diabetes relationship with COVID-19 just beginning…there is so much we don’t know yet.

The porcupine’s winter in slow-motion – How do porcupines in Alaska survive being out and about in the winter?

Top 25 birds of the week: Bird Interactions – Mostly adults of the same species…but there are a few with different species and the first image is a pair of young owls (siblings).

2,000-Year-Old Roman Bowl Discovered Intact in the Netherlands – Blue glass that look like it could have been made very recently.

Locations of ancient Maya sacred groves of cacao trees discovered – History of cacao (chocolate) trees…grown around sinkholes…so special that the beans were used a currency.

Monarch butterfly numbers soar in California after dramatic losses – It’s great to have some good news about Monarchs….but they’re still a species that needs our help.

AccuWeather shares how an electric school bus fares in Alaska – Evidently the bus has done well even at -48 degrees Fahrenheit!

Musings from the parks: Navigating National, Wild, Recreational, and Scenic Rivers – Prompted by a proposal to refine limits on the horsepower boaters can use in Ozark Scenic Riverways in Missouri…a look at regulations at other rivers in the National Park System. I’d prefer that we begin the transition to electric motors (if motors are allowed at all) rather than only focusing on horsepower.

Epidemiologists develop advanced state-of-the-art tool for measuring the pace of aging – A blood test to measure the pace of biological aging…with the possibility of identifying interventions that would slow aging… and attempt to build aging health equity.

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.

The Roots of Violence – Reexamining bones excavated in the 1960s with new 3D imaging techniques….defining the violence of their lives and deaths shown in the bones. There is a history of archeological thinking here too. For a long time, evidently there was a presumption that prehistory was a less violent time…but the evidence is mounting that it was not.

Reducing air pollution: policies that pay off – An analysis done in Europe of the economic benefit of measures to reduce fine particle air pollution from wood heating and transport. It seems that similar type analysis could happen in other places in the world with some variation to tailor the reductions to have the biggest impact.

30 Incredible Winning Photos From the 2021 Nature Photographer of the Year Contest – Some eye-candy. My favorite is the caterpillar ‘walking among fennels’ – a similar scene happened at our CSA the first summer of the pandemic.

Assessing the U.S. Climate in 2021 – There were 20 separate billion-dollar weather and climate disasters that impacted the US in 2021.

Savanna Fire Management Can Fund Africa’s Protected Areas – Another article about the new economics we will need to understand to address climate change.

The forgotten medieval habit of 'two sleeps' – Maybe one long period of sleep is ‘modern’….that humans slept in two phases prior to the industrial revolution. One of my grandmothers developed a ‘two sleeps’ pattern late in her life when she was living alone….and I am beginning to wonder if I will.

The Horned Helmets Falsely Attributed to Vikings Are Actually Nearly 3,000 Years Old – Another look at artifacts…and better dating…and the history derived/assumed previously is changed.

Top 25 birds of the week: bird coloration! – This time of year…a little color from birds is a welcome sight. I’m noticing the ones in my neighborhood: Northern Cardinal, House finches, and red-bellied woodpeckers.

Across the Boreal Forest, Scientists Are Tracking Warming’s Toll – The northern forests becoming carbon emitters….. peatlands are drying out, and hotter, drier conditions are leading to a steady increase in wildfires — all of it accelerating permafrost thaw.

The Legacy Of "Pele's Grandson," Alex Lancaster – Some history of volcano observation on the big island.

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.

How driverless cars will change our world – A little realism in the projections….rather than hype. Hopefully by the time I am old enough to no longer want to drive myself, driverless car options will be convenient and safe.

Ubiquitous food additive alters human microbiota and intestinal environment – The research was about carboxy methyl cellulose specifically. As I read the article, I wondered if this additive -that isn’t really about the nutritional value of the food at all – is one of the ways ultraprocessed foods are bad for us in unintended ways.

120 Volt Heat Pump Water Heaters Hit the Market and Make Gas Replacements Even Easier – This is good news. I’ll be watching as these come on the market…see how they are reviewed. I am assuming a line will quickly form with people wanting to replace their gas hot water heaters!

When Wildfire comes to Nature Conservancy Preserves – The preserves are managed with prescribed burns and forest thinning…and can provide examples of effective ways of managing wild areas against destruction by wildfire.

Children’s Teeth Reveal Breastfeeding Practices in Ancient Peru – A detailed study of the remains of 48 children from 2,500 years ago revealed that they were breastfed exclusively for the first 6 months of life and were weaned when they were about 2.6 years old. I wonder how many other ancient cultures have been studied this way.

Transparent Solar Windows: You Ain’t Seen Nothing Yet – If solar windows could be produced at reasonable cost….a lot of people would be motivated to replace their windows/power their house. There is a pleasing aesthetic to this type of solar power too.

Why Putting Solar Canopies on Parking Lots is a Smart Green Move – A great idea…hopefully it becomes the norm. The first one I noticed was at the Patuxent Research Refuge.

Top 25 birds of the week: Nectar Feeding Birds – Always worth looking at some bird pictures!

The Colon Cancer Conundrum – Research is trying to determine why rates of colorectal cancer are climbing in younger adults….staying level for other age groups.

Our National Monuments, a Photographic Testimonial to Wild America – Some more places I want to visit (via an extended road trip perhaps).

National Park Service Publications on Internet Archive

/

Last September - I browsed 18 publications from the National Park Service that have been scanned and are freely available on Internet Archive. They are all decades old….reflect history of the places. The oldest one is from 1917 (The National Parks Portfolio) which is clearly a snapshot from the early years of National Parks. I was particularly interested in the “Astronomy and astrophysics national historic landmark theme study” published in 1989 – the year my daughter was born and she has grown up to be an astrophysicist! The only park I visited before the publication was Yosemite; the publication is from 1990 and I visited in 1984. I’ve provided a sample image for each volume. Enjoy some armchair traveling with some browsing via Internet Archive…find some correlations in the publications and your own life.

Wind Cave, 1979

Agate Fossil Beds National Monument, Nebraska, 1980

Astronomy and astrophysics national historic landmark theme study, 1989

Venturing Out and Weekly Gleanings

Continuing the blog post series prompted by COVID-19….

A Zentangle Prompt

20190401_140347.jpg

Inspiration for a pattern can come from our environment. Sometimes creating a pattern is relatively straightforward. The prompt for today is to create your own pattern based on the picture of tiles to the right. Hint: start with a grid of squares. Use your pattern in a tile. Other patterns in the tile are tangler’s choice (i.e. whatever you want).

Here are some tiles I made based on yesterdays prompt: Make a tile using the gingo pattern.

It is one of my favorite patterns for mono-tangle tiles.

Venturing away from Home

I went to Howard Country Conservancy’s Mt Pleasant to record a Facebook Live Zentangle session. It was the first time I had driven my car in May! It was also my first volunteer gig since early March – and a good experience – but I realized how out of practice I have become with getting out and about. There was a ‘newness’ to my car even though I’ve had it for a few years. Mt Pleasant is a place I know very well but hadn’t been there since January; it felt unfamiliar.

I was glad the flip chart pad and gallery board were wrapped in plastic trash bags because it was raining heavily when I got there. It took two trips to get into the building and I was glad I had worn a windbreaker and waterproof boots.

The mask that I wore during set up did not stay in place as well as I wanted. I need more experience with securing it and being certain that I can breathe well enough through the layers of fabric. It’s a good ‘lesson learned’ before I venture out to try doing my own grocery shopping in June.

The materials I had prepared ahead of time worked well…minimizing the amount I had to create while I was talking.

The Facebook Live session lasted about 20 minutes and made a three-part tile using TIPPLE, CRESCENT MOON, and either MEER or POKEROOT. I missed not being able to create a mosaic of the student tiles at the end. Here are tiles I made with the patterns after the session.

I’m not sure how any of my volunteer gigs will be possible anytime soon but I’ll probably do some hiking at Mt. Pleasant…on a sunny day…another small ‘venturing away from home.’

Gleanings of the Week

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.

Soak in the Details of the Moon with this High-Definition Photo – A backyard astrophotographer with a lot patience.

Record conservation study of Tutankhamun's tomb solves mystery and raises new questions – Teasing out more history from a much-studied place.

Top 25 birds of the week: Bright Colours - Wild Bird Revolution – It’s a gray rainy day as I write this….I am appreciating the colors!

New Thoughts on Turkey’s Oldest Temple Complex - Archaeology Magazine – Gobekli Tepe…built by hunter gatherers over 11,000 years ago….requiring hundreds of people to construct. I first learned about it in a Coursera course a few years ago.

NASA's ICESat-2 measures Arctic Ocean's sea ice thickness, snow cover -- ScienceDaily – ICESAT-2 was launched in September 2018; I learned about it during visits to NASA Goddard during my HoLLIE class in spring 2018. It’s good to get an update on it now.

The ingredients for a longer life - BBC Future – Study of populations where many live to 100…focusing on eating habits, social connection, a few cups of tea or coffee, sweet potato and bittersweet melons, landscape…and moderation.

Saving energy and lives: How a solar chimney can boost fire safety -- ScienceDaily – If a building has a solar chimney, it will suck smoke out of a building during a fire…giving people more time to escape!

Risks of Clutter, Tips for Decluttering Your Home | Berkeley Wellness – I had intended to spend some of the ‘stay at home as much as possible’ time de-cluttering. But I moved on to other projects. Now I am returning to the idea just as I am beginning to tentatively venture out. The clutter in my house is not enough to make it unsafe…but I do have a lot of stuff that I no longer need.

Tracing the human genetic history: Every tooth tells a different story – Another data point for forensics when DNA is not available. Teeth often survive for longer than other parts of the body.

New evidence of watery plumes on Jupiter’s moon Europa - GeoSpace - AGU Blogosphere – I’m missing Charles Cockell’s Life in the Universe Pandemic Series. This article is about new analysis of data collected by the Galileo mission flyby of Europa in 2000.  The ESA Juice mission, which is scheduled to launch in 2022, will study the potential habitability and underground oceans of three of Jupiter’s moons: Ganymede, Calisto, and Europa.

Top 25 Wild Bird Photographs of the Week: February 2020 – Note the new website for these weekly posts: https://wildbirdrevolution.org/ ---The posts are still the beautiful bird pictures collected into a group for a weekly visual celebration of birds.

100% Wind, Water, & Solar Energy Can & Should Be the Goal, Costs Less | CleanTechnica – A short summary of a report with specifics for 143 countries…getting to 80% renewable energy by 2030 and completing the transition by 2050. Now to vote with that goal in mind for a livable future for ourselves, our children, our grandchildren….and onward.

LEDs, Downward Lights Changing the Night in Chicago - News | Planetizen – Chicago will complete the transition to energy efficient LED streetlights in 2021. They’ve calculated that it will save the city $100 million over 10 years. At the same time, they have made an effort to focus the new lights downward to cut light pollution. It’s too early to tell if that aspect of the project will be a success.

Vegetation Filters Harmful Particulates from Air--But How Much? | The Scientist Magazine® - It’s probably better to push for the transition to renewable energy (in school buses, for example) but where that is not happening fast enough – planting a green wall of vegetation can block pollution from school yards…which could reduce the impact of vehicle exhaust on children’s lungs.

Decline in Coal-Fired Power Reduces U.S. Carbon Emissions in 2019 - News | Planetizen – Good news…but it could decline more quickly. The 2019 results are from market forces alone. If there were political will, things would happen even faster.

Archaeologists Excavate 200 More Chinese Terracotta Warriors | Smart News | Smithsonian Magazine – The first terracotta warriors were found in China’s Shaanxi province in 1974. Now there is more excavation and more soldiers from the same tomb. All the warriors have unique expressions, hairstyle and physical features.

Organic crop practices affect long-term soil health -- ScienceDaily – This study looked closely at organisms in the soils…along with the impact of prior soil disturbance.

Recovery: A Plague of Bullfrogs – The Eastern part of the US is the native range for Bullfrogs…but they are invaders in the West. They are clearing native frogs and eating other animals too (ducklings are an example cited). So various municipalities and conservation groups are acting.

What We Can Learn From Ötzi the Iceman's Hunting Pack | Smart News | Smithsonian Magazine – Ötzi was preserved for 5,300 years in a glacier until he was discovered in 1991. A lot has been studied since that time. He’s a window into Copper Age Europe.

Photography in the National Parks – More favorite spots for photography from Rebecca Larson. This collection included three National Parks I have not visited: Glacier, Olympic and Mount Rainier. Now I want to plan a trip to see them!
