A sweet little cliff in the area of the twin sisters. I believe there is only one route on the formation. A great place to go to escape the crowds of the main city.
From the campsites by the twin sisters follow the two track with a locked gate west for about 10 min, until you see the obvious Skinner's Roof. Head up and left of Skinner's Roof through sage brush and faint cow trails. The nice left facing corner in the center of a small formation is White Lightning.
