This obscure butte/tower is between Tomsich Butte and Square Top on the east side of the Reds Canyon road (Park in a wash off the Reds Canyon road at 38.74205, -110.94416). Yellow Cake comes from the abundance of uranium mining in the area. The rock quality on this pitch is excellent and clean (kind of rare for the area) except for 8 feet of soft rock near the top. Expect a steep ~45 minute approach.

The route begins on the northwest corner of the formation and is obvious. Climb the splitter to a small ledge (5.9 with optional belay if short on cams). Be careful there is some loose rock on this small ledge. Continue up the crack to the top which has a tricky mantle with soft rock. Finding anchors on the top tricky due to the poor quality of the rock.

Walk 100 feet east from the summit to a bolted rappel anchor and rappel south 70' to the ground.


The summit of Yellow Cake is located at 38.7320, -110.9417
