An asbestos deposit occurrence in the bottom of the Grand Canyon and side canyons. The property extends for some 9,000 feet down river from the cableway. Owned by the Hance Asbestos Co., New York.

Mineralization is hosted in Precambrian Bass Limestone altered by diabase sills (Shea basalt). The larger veins of chrysotile lie in limestones that are beneath the diabase sill. The smaller veins above the sill are more widely distributed. The veins beneath the sill may lie anywhere from 5 to 15 feet below the limestone-diabase contact.

Workings include a cableway installed about 1,200 feet above the river.
