Pointless Prize: 2022 Photo Scavenger Hunt

2/19/2022 Paleontology

Knowing I had limited time today for a ride, I thought to check the USGS website to see whether the USGS headquarters here in Reston had any rocks displayed on their grounds that contained fossils. I wasn’t able to find any information indicting that they did. Nevertheless, I headed there early this morning before work to check out the section of their grounds open to the public. No luck. BUT, the USGS has a paleontology program going back at least to the 1930’s. My offering for today’s photo scavenger hunt is the USGS.

Fun fact: the IFC building at 2121 Pennsylvania is faced with marble taken from a quarry that contains fossils from about 160 million years ago. (link to more information)

I’m out of town on s biking/hiking trip in Douthat State Park. This is a photo of a footprint we found in one of the books in the cabin. Stretch your brain to a million years from now, and it will be fossilized!

Start of the Downtown Breakaway ride on Wednesday evenings. Does anyone ride that? Great for all abilities from sensible racers to D pace riders.

“These shells sat on the bottom of an ocean, on sand that later became the Appalachian mountains. (Chris Barr)
Look at the outward-facing walls on the southwestern corner of the park and you’ll find gray and white shell shapes pressed into some of the stones. These were brachiopods, shelled creatures that dominated the ancient seas but are less common today. The brachiopods that left their mark here probably lived during the early Devonian period, a little less than 400 million years ago, in a coastal area that now makes up the Appalachian Mountains. “This park has been renovated many times, and at some point they put in one of the best fossil displays in the city,” Barr says.”

“According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn’t correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton’s picture of a universally ticking clock. Even Albert Einstein’s relativistic space-time — an elastic manifold that contorts so that local times differ depending on one’s relative speed or proximity to a mass — is just an effective simplification.”

The “Sherman Logs” outside the National Museum of Natural History in DC. They are 207 million years old, stony relics of an ancient conifer (Araucarioxylon arizonicum) that once flourished in prehistoric Arizona.

The City of Alexandria has set up a taxi meter course on Eisenhower Avenue with signs that run from 0 – 6 every 1/6 of a mile to measure the proper calibration of taxi meters. Taxi meters are calibrated in 1/6 mile increments.

Very precise measurement here. A metrologist should be proud.

The Zero Milestone, located on the Ellipse in front of the White House, is a zero mile marker monument intended as the initial milestone from which all road distances in the United States should be measured when it was built.
