|Location and accuracy||This prospect is on the ridge west of lower Stratton Creek. It is at an elevation of about 4,000 feet, 3,500 feet west of Stratton Creek in the NW1/4 of section 34, T. 14 N., R. 9 E. of the Copper River Meridian. It is approximately located, perhaps to within several thousand feet.|
Geologic descriptionA thin belt of serpentinite extends west-northwest from near Stratton Creek to north of Mentasta Lake (Richter, 1967, 1976). Mining claims for asbestos have been located near the east end of this belt (U. S. Bureau of Mines, 1995; Kardex location MILS 0020780090). The serpentinite locally contains rodingite inclusions with thin nephritic rims and lenses of magnesite-dolomite-silica rock (Richter, 1976). This alpine-type ultramafic body is within Devonian metasedimentary rocks and is considered to be Cretaceous (Richter, 1976).
