Comments: David, there's only part of one DH crag in the Rock Climbing Colorado book, and of the 60 or so crags there, it's among the lower 1/4 in overall quality. A quick scan of the book at one of the local shops should be enough for you to decide if it's a worthwhile purchase.
This long secret Utah area is well guarded by 25 miles of 4WD road that now sometimes washes out in the rain due to the fire. It's really baffling why such a remote and hard to get to place has been kept such a big secret.
Comments: Warning - the rock quality here is predominantly choss, decomposed rubble, and dirt. One of the routes on the right side even features a 1 foot square block "glued" in at the crux. Ra is a much better alternative. The day we were there another party showed up and after only one route left the area and headed home even though it was a nice day.
