Gleanings of the Week Ending June 13, 2015

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.

18 beautiful houses for tiny people - Photographs of doll’s houses …inhabitants and furnishings too.

How past Native-American settlement modified Western New York forests - Larger nut-bearing trees were more abundant near settlements!

Rebuilding Sandbars in the Grand Canyon - I had learned about the attempts to rebuild sandbars in the recent Coursera offer on Water in the Western US…so this acted to remind me of the class, probably locking in what I learned through a surprise repetition.

Ultrasound is making new waves throughout medicine - Ultrasound is being used for more and more imaging these days….and is more portable than a lot of the other imagining technologies.

10 Ways to Save Pollinators - This is not just about honey bees….it’s about all pollinators.

Multi-tasking: Benefits on exercise - So doing something else while you exercise may not be such a bad thing!

Beyond Automation - Five paths toward employability is an automated…augmented world of the future.

Sewage Pollution: The Next Great Threat for Coral Reefs - 96% of places that have both people and coral reefs have a sewage pollution problem (85% of the waterwater entering the sea in the Caribbean is untreated). Sewage that reaches corals includes: fresh water, endocrine disruptors, heavy metals, pathogens, toxins. Ewww! Not good for human health either.

The Shifting Sands of the Sahara Are a Lesson in Dune Dynamics - Illustrations of dune patterns (seen from above)

5 Ways to Make Environmentally Conscious Food Choices - I had thought of all 5…but this is post is a good summary to: support good companies, buy local, storing your food, growing your own, and choose less packaging.

Nature and History Hiking

There are lots of ‘stories’ that we create for ourselves while hiking. Hiking is active and invites narrative. The theme can be about interaction with an animal or plants or a hiking partner. There could be an activity done with hiking that becomes part of the story: photography, bird watching, climbing, camping, etc. Recently - I’ve been creating stories using the history theme.

The longest timeframe history is in rocks - in layers. It is easy for this narrative to emerge when hiking the Grand Canyon…..the feeling of the vast amounts of time for water to wear away the rock is part of the place.

Sometimes rocks tell history with a shorter timeframe. For example, rocks along trails in areas that are near developments show up in buildings; the Master Naturalist hike along the Trolley Trail early this year was an example for me of rocks linking to history of the past few hundred years. A building not far from the trail was built of Ellicott City Granite with bits of amphibole for contrast.

Human impacts. Sometimes the changes caused by humans are evident along a hiking trail. Trash is always unwelcome and we may not hike that trail again - or help in a clean up project. It is a sad story. In fact - lots of the impacts are sad: eroded stream banks from changes in runoff patterns from housing developments and invasive plants. Many of the impacts happen quickly.

Other examples of human impacts take a longer period. The view of the forests on the east coast has changed dramatically now that the American Chestnuts are gone (almost all of them succumbed to the Chestnut Blight in the 1900s); they were the dominate (most numerous) tree in the forest. That history is harder to realize because it is about something missing. As I look into the forest behind my house - the most numerous trees are the tulip poplars. They are tall - but they don’t produce the large and reliable crop of nuts that the chestnuts did (for animals and people).

What about organisms that are not usually noticed? If you take a walk shortly after a rain - there might be earthworms on the forest path. Did you know that they are not ‘native’ to North America but brought in ballast from Europe during colonization? How did they change the forest? The leaf mulch was not cycled as quickly by the native organisms which means that the forest floor in precolonial times was cooler and wetter than it is now. How different did those forests look?

Coursera - May 2015

Both of the courses from April are finishing up and I’m determined to not load myself up with new courses in May because I have so many outdoor activities planned for the month.

I did enjoy both of the April courses. Maps and the Geospatial Revolution course is immediately applicable to a Tree Tour I am doing as a project for my Master Naturalist certification. It will include a map, of course.

The Water in the Western US course was good on a number of levels. There was a segment on how they are adding sediment back to the water flowing into the Grand Canyon to rebuild the sandbars there (and it seems to be working)….brining back memories of the place from earlier this year. One memorable and scary factoid from the course: The Central Valley of California has subsided significantly since the 50s and 60s and is now below sea level; levees are all that separate it from San Francisco Bay….all the fresh water in that area (water supply for San Francisco) could become saline within days if an earthquake caused those levees to fail!

Pinyon Pines and Birds in Arizona

Two topics today - both from Arizona: pinyon pines and birds.

Pinyon pines are part of the landscape of the Grand Canyon. I have always been fascinated by their cones. They are short and squat and often full of sap. I learned that the hard way on a trip across New Mexico in a new car 30+ years ago. I picked up some pinyon pine cones and put them on the dash of the car - enjoying their wonderful smell as we continued our road trip. The sap stayed on the dash for years! I am enjoying the pictures I captured this time. The first picture is of a cone that has already lost its seeds; the second and third are developing cones.

I accidently took some good bird pictures in Arizona. They were accidents in that I was not set up to photograph birds; I was just being opportunistic. The varied thrush was in the parking lot of the Petrified Forest Visitor Center! The bird is a little out of normal range according to allaboutbirds.com.

The next three birds were in the alleyway outside my son-in-laws research greenhouse in Tucson (I was waiting outside after getting too hot in the greenhouse). The mockingbird kept an eye on every move I made but rummaged in the pebbles for food. This bird lives year round all of the US but they are usually too nervous for me to photograph.

The curve-billed thrasher felt secure on the electrical line. The wind ruffled the feathers periodically making the bird look rather scruffy.

The white-wing dove was also overhead on the lines. The red eye outlined in blue and the white tips on the wings are distinctive….and the ruffling of the feathers by the wind is too.

I am learning to always be prepared for bird photography in unlikely places!

On the Road in Arizona

I enjoy being a front seat passenger on road trips and catching the landscape ahead of the car. Our road trip within our vacation to Tucson was a great opportunity. I’ve perfected my technique over the past few vacations: make sure the windshield is clean, zoom a little to get the car out of the picture, and try to keep the horizon level!

My daughter did all the driving:

• From Tucson to Flagstaff (via Phoenix and Sedona, images 1-8 in the slideshow below),
• From Williams to the Grand Canyon in the early morning (image 9), and
• From Petrified Forest National Park back to Tucson (via Show Low and the White Mountains).

We had plenty of variety in the sky: clear blues, sunrise colors, patches of clouds building and a golden sky near sunset with rain not quite reaching the ground from dark clouds. There were roads winding and straight…up hill and down. Mountains with snow and mesas and buttes. Lots of red rock. Grasses, pines, scrub, and saguaro.

Enjoy the Arizona scenery from the road!

Grand Canyon National Park

I’ve been to Grand Canyon National Park three times:

• When I was in high school - in early spring 1971 when I walked a little ways down Bright Angel Trail then turned back when it started snowing.
• In May 1983 when my husband and I walked down the Bright Angel Trail to the plateau level. I remember blisters from the too-new hiking books and my legs feeling like jelly for most of the walk back up.
• In January 2015 when it was cold and breezy. We drove to the park through early morning light and saw a bald eagle landing in the top of a pine tree beside the highway. I wasn’t fast enough to get a picture but it started out the day right. The pictures below are from the visit a few weeks ago.

It is hard to fathom the sheer size of the place. The rim trail on the South Rim - accessible from many points - is an easy walk to try to get perspective. We were early enough that the haze had not burned off completely and sometimes the vegetation seemed to glow from light within.

There has been a lot of building in the main park facilities since 1983. I liked the way the paving incorporated different colors of concrete to make designs - spirals and gentle curves. But we didn’t stay in the developed area long. We decided on our plan for the day - settled on where we would eat lunch (Maswik Lodge Food Court) and began working our way toward Hermits Rest stopping at just about every overlook. After lunch we headed in the opposite direction (toward Desert View) where we would leave the park and head to our hotel about sunset. Along the way we saw rapids and twists of the river below, a mini-snowman, beefy crows, and the zigzag of a trail into the canyon. Sometimes I took pictures of lichen and small plants just to not be overwhelmed by the Grand Canyon vista!

I am already thinking about when I can go again!

Ten Days of Little Celebrations - January 2015

Noticing something worth celebration each day is an easy thing for me to do. The habit of writing it down reminds me to be grateful for these and a myriad of other things in my life. This month has been full of ‘little celebrations’ - as had been the usual for the past few months. Here are my top 10 for January 2015.

Winter

Snow in Tucson. The year started off with a pictures from my daughter of the snow they got --- on the palms and cactus near their apartment. It was a beautiful scene to celebrate the New Year.

Fox. A healthy looking red fox walked through our back yard then trotted behind several other houses before turning into the forest. I watched from the window of my office - celebrating the grace of the animal as it moved through the winter landscape.

Fog. The forest and our neighborhood filled with fog. The temperature was in the upper 30s. It seemed like the fog damped sound as effectively as it did sight - celebrating a warm house in the isolation of winter.

Snow. Snow that falls when I can simply stay at home until it melts or the streets are cleared by the plows is my favorite kind of day. It is the classic winter scene worth celebrating.

Other

Dishwasher. Our dishwasher became very loud so we arranged for servicing - anticipating that it would have to be replaced. Hurray! It was quickly fixed and our kitchen is a quieter place.

Zentangle® class. I saw a blurb about a Zentangle class offered at the local 50+ Community Center. It was a good incentive to investigate the place! I’ve been to the first of four class sessions and am enjoying daily ‘tangling’. I’ll post a slide show of my creations once I’ve accumulated a few more. I’m celebrating both the class and learning about the 50+ Community Center.

Arizona and Tucson

Bald Eagle. In recent years, the bald eagle population has increased on the east coast and we see them more often….but when I saw one as we drove into Grand Canyon National Park - settling into the top of a pine tree - it was a first sighting in the west for me. Hurray!

Grand Canyon. Awesome place. I’ve been there before --- it is worth celebrating again and again.

Painted Desert/Petrified Forest. The times I’d been before were in summer and late spring. This time it was decidedly cool/cold. The colors were deeper in Painted Desert because it had snowed/rained. The Petrified Forest glistened when the sun came from behind the clouds. Both places are special…and worth celebrating.

Tree Ring Lab. I’m celebrating that the place lived up to my expectations - interesting from scientific, architectural and historical perspectives. If I lived in Tucson - I’d sign up as a volunteer docent.
