Click Photo to EnlargeThis large, semi-circular feature can be found somewhere in the west. Only one paved road is reputed to run through it (I will personally attest that one paved road runs through it; I can't attest that it is the only one). Supposedly no one lives there, although I have seen people selling things inside the feature. The photo was taken from an eastbound airliner, looking approximately north. The color in the photo is perhaps slightly extreme in a few places, though maybe not by very much.
At least two geo-blogospheric types are known to have been to this feature (besides myself) - I can't exactly invoke a Schott Rule, but if you have your field camp here, perhaps you can wait an hour or more. (Or not.) Can you name any of the geomorphic and structural features either seen in the photo or found while traversing the area on the ground? And can you name any of the rock formations and their ages? Name the cliffs or formations in the background for extra credit. (Oops - "cliff" - that's a geomorphic feature!)
Sorry, no T-shirts!
