This area is N. of Yucca Valley/Pioneer Town . There is a fair bit of rock, and probably lots of bouldering, but we found only one formation large enough for roped climbing in this area. There are 3 climbs on this formation. (left to right) Underware Gnome, Do you Believe in Leprachans, and Granny Panties, all 5.8 and all have 3 or 4 bolts to 2 bolt anchors.
You will need a map. From Yucca Valley, drive north through Pioneertown, and then further north to Rimrock area. From there, a maze of dirt roads lead to this area. (good luck)....
