2016 UPDATES of MY AMATEUR IMPACT CRATER/STRUCTURE EXPLORATIONS

This image illustrates dark material deposited in a linear manner in a natural groove in the bedrock by wave motion. This explains the “dark” pseudo-crater rim that I saw from the air.

The joints were spaced about a foot apart there, some 10 times closer than jointing elsewhere in the surrounding rocks. That’s what governed the circular course of the creeks – water will preferentially erode away rock where it’s weaker and so areas of the bedrock with more frequent jointing will eventually form creek valleys. .(Hudson Valley Geologist)

I am balancing half way up the crater rim and holding a birch branch so it hangs vertical. Referencing the vertical branch with the one placed on the rim, the angle is ~50°.

“We, all of us, are what happens when a primordial mixture of hydrogen and helium evolves for so long that it begins to ask where it came from.”
