The prospect is in West Chichagof-Yakobi Wilderness.
Location: The Snow Slide prospect is at an elevation of about 600 feet, about 0.15 mile north of the north head of Baker Cove in Goulding Harbor. The prospect is 0.5 mile west of the center of sec. 18, T. 47 S., R. 57 E. It is location P-47 of Bittenbender and others, (1999), location 19 of Cobb (1972, 1977), and MAS no. 0021140107 (U.S. Bureau of Land Management, 2002). The location is accurate within about 0.5 mile.
Geology: Johnson and Karl (1985) map the rocks in the area of this prospect as the Freeburn assemblage, a collage of kilometer-scale, fault-bounded, lozenge-shaped blocks of Cretaceous and Cretaceous(?) metasedimentary and metavolcanic rocks. The rocks are cut by high-angle, mainly northwest-striking faults, one of which transects the prospect area. Cobb (1972, 1978), citing Overbeck (1919), describes the prospect as a 6-foot zone of quartzose greenschist containing pyrite, chalcopyrite, and possibly some pyrrhotite. Two claims were located in 1916. A 171-foot tunnel driven to intersect the zone at depth did not reach it.
Workings: Two claims were located in 1916. A 171-foot tunnel driven to intersect the mineralized zone at depth did not reach it.
