Above Sedona, Arizona, off the Brin's Mesa trail. Looking roughly southeasterly. Map location is approximate.

Along the west side of the Grant Range, Nye County, Nevada. They're mapped as lower Paleozoic (Ordovician Pogonip Group), according to the Nevada Division of Mines & Geology Bulletin 99A. It looks like an extremely interesting area, but I haven't been over there and don't know what the access is like.

The cliff below Notch Peak itself, on the right, is some 2700' high. I've seen it asserted that it's the tallest cliff in the Great Basin, but I haven't been able to track down the reference.
