Geologic information

Identification information

Deposit ID 10307753
Record type Site
Current site name Cairn Mountain

Geographic coordinates

Geographic coordinates: -155.30707, 61.20102 (WGS84)
Relative position Several occurrences of placer gold are present in a several-square-mile area along the northern flanks of the Cairn Mountain upland (Eppinger, 1993). The map site is at an elevation of 1,300 feet on one of the drainages flowing north from these uplands in the NW1/4 section 24, T 13 N, R 34 W, of the Seward Meridian. The map site is chosen to represent the general area of gold occurrences.

Comments on the geologic information

  • Geologic Description = Pan concentrates from several drainages in this area contain detrital gold (Eppinger, 1993). Most of the gold is well-rounded and flat. Bedrock in the area is dominantly Cretaceous clastic sedimentary rocks (Eppinger, 1993).
  • Age = Quaternary.
