In the Wingate sandstone layer Jurassic in age. A crack brings you to some bomber holds before you reach the flakey top of the problem which juts out. It is good to have a spotter since the rock is fairly gritty at the top and you can loose your grip easily. ABout 15 feet high. Not too hard, but fun and lots of variations. Chalk doesn't seem to help much since the rock is already very dry nd gritty.
