A large hill (officially called Adam's Butte) covered in numerous boulders. Rock is durable and solid, but mostly undeveloped so loose holds are a problem. Lots of options to develop a plethora of easy boulders and a handful of more challenging problems as well. This is but a sampling of the area, I put up around 20 problems in an evening and the next morning before it got too hot to handle.
Continue less than a mile south on Lonesome Beaver rd from the first group of boulders. Roughly 10 1/2 miles from Hanksville Post Office. You'll see a butte on the right covered in dark boulders. Park on the side of the road or continue past the formation to a large pullout across from the corner of the fence on the left. GPS point for this area is marking this parking spot.
