Location: The Bear Creek prospect is at an elevation of about 200 feet on a north-flowing tributary of Bear Creek. It is 3.5 miles south of Lone Mountain and 2 miles east of the head of Funter Bay. It is near the center of the NE1/4 section 5, T. 42 S., R. 65 E. of the Copper River Meridian. The location is accurate within 1/4 mile.
Geology: This prospect is in amphibole-mica schist, and consists of a vertical layer, 18 inches thick of tremolite asbestos that strikes N. 45 W and can be traced on the surface for 60 feet (Race and Rose, 1967; Wells and others,1986). The deposit contains veins of cross-fiber asbestos 0.75 inch thick and 6 to 8 inches long (Cobb, 1978 [OFR 78-374]). Prior to 1930, the Alaska Asbestos Company, Inc. dug an opencut across the belt of tremolite schist, and constructed a road from the beach to the property (Roehm, 1943). The rocks in the general area are mainly Ordovician and Devonian to Triassic clastic units, mafic-intermediate volcanic rocks, and subordinate limestone. The bedded rocks are intruded and locally metamorphosed by Cretaceous granodiorite (Gehrels and Berg, 1994).
Workings: Prior to 1930, the Alaska Asbestos Company, Inc. dug an opencut across the belt of tremolite schist, and constructed a road from the beach to the property (Roehm, 1943).
