there's some beta on mnt project:
they show about 8 routes there at 2 different areas.
it's pretty easy to climb with no guide up there, as one can easily roll up the canyon, and look for the prime lines. maybe bring some binocs to look for teh rap anchors. although you may have a hard time seeing them, as lots of them may be painted or set where you can't see them (hopefully). kind of ballsy to head up something with no assurance of descent, though....i bet if you stick to plumb looking cracks you'll be fine. bring lots of 2's and 3's. i rememeber climbing at at least 5-6 different areas, lots of good 10 cracks.
there's also unaweep canyon, that is covered in mnt. proj. and std. guides right there too. if you're more into the sandstone, though, there's even sandstone routes at the beginning of unaweep on the right side of the canyon as you're driving up.
have fun - S
