A pegmatite located in NΒ½ sec. 5, T. 4 S., R. 71 W. It is exposed by a roadcut along U.S. Highway 6 in Clear Creek Canyon, 3 mi east of the fork between U.S. 6 and the road to Black Hawk (State Highway 119). Much of the deposit has been removed by excavation for the highway, but several smaller dikes crop out on the hill above the roadcuts.
Mineralization is a zoned pegmatite structure in biotite granite gneiss.
