Location and accuracy Occurrences of placer gold are present in a several-square-mile area centered on USGS benchmark Anchor (Eppinger, 1993). The map site is at an elevation of 1,500 feet on one of the drainages flowing north from these uplands in the SE1/4 section 34, T 16 N, R 31 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 (Eppinger, 1993). The gold is subangular to angular and includes some grains to 1 mm across with very delicate features, such as serrated edges (Eppinger, 1993). Bedrock in the area is dominantly Cretaceous clastic sedimentary rocks (Eppinger, 1993).
