This is a nice chunk of granite in the narrows of Boulder Canyon. It is been largely ignored by rock climbers, with the exception of a few obscure sports climbs at its base. However, for a few awesome winters, it was a site of excellent ice farming. A number of fine 1-3 pitch ice climbs were created. Hit and Run, Meow Mix, Mellow Yellow, Book of Secrets, Brown Recluse, Winkelman, Second Leg, Virtual Recluse, Virtual Reality, Scotty Gully, The Kerbash.

Drive up W Hwy 119 (aka Canyon) from the villa of Boulder past Boulder Falls. As you enter the narrows, about 8 1/2 miles from the Elephant Buttresses, there is a maze of rocks on the S side of the canyon, across from Boulder Creek. Just upstream from Vampire Rock (a medium sized chunk of rock about 3 pitches high) is a slightly lower angled mass called Black Widow Slab.
