Location and accuracy Drainages in a several-square-mile area northwest of Sparrevohn Air Force Station contain detrital gold (Eppinger, 1993). The map site is at an elevation of 1,250 feet on one of the drainages flowing northwest from the Sparrevohn uplands in the SE1/4 section 15, T 12 N, R 36 W, of the Seward Meridian. The map site is chosen to represent the general area of gold occurrences.

Geologic setting

Geologic description

Pan concentrates from several drainages in this area contain detrital gold, and one contains gold and cinnabar (Eppinger, 1993). Most of the gold is well-rounded and flat, except for that in the one sample that contains cinnabar. Bedrock in the area is dominantly Cretaceous clastic sedimentary rocks (Eppinger, 1993).
