Hugemoth, I thought that my little trailer was a semi-offroad ultralight, but yours can apparently fly, too! What are you using for a tow vehicle -- a 747? ;)
Seriously, though, that is an amazing and thought-provoking shot! You've got to wonder how those alternating layers were deposited.
The hills are actually the result of a massive volcanic ash fall from the Cascade Mountains over 33 millions years ago. Natural processes changed the deposits into a type of clay (Bentonite) that expands as it absorbs water creating the close-up popcorn-like appearance. The colors are the result of minerals -> red from iron oxides, yellow from iron & magnesium oxides and lavender from rhyolitic lava.
