Warren Teissier on the the Corkscrew Summit of Ancient Art (2003).
This is probably the most insane summit of any tower in the
desert southwest, possibly even the world!
I am not standing on "the ground", but at the top of the third
pitch on the climb. In fact what you see is precariously balanced
on a fin of rock only 2 feet wide at the top and 300 feet high!
Needless to say, this is an exposed spot. This last pitch remarkably goes
at only 5.8.
