Comments on the geologic information

  • Geologic Description = Rocky Mountain Creek has been mined for gold, and concentrates contain scheelite (NM082). The creek was one of six creeks on the Seward Peninsula that have been identified as possibly containing important amounts of scheelite (Coats, 1944, p. 6). This prospect is on a linear feature mapped from aerial photographs by Hummel (1962 [MF 248]). The linear appears to closely coincide with the scheelite-bearing vein and scheelite-bearing float that was traced from Rocky Mountain Creek southerly for 4,000 feet to Nelson Gulch (Coats, 1944, figure 4). Bedrock in this area is a calcareous schist that gradationally overlies quartzite and schist (Hummel, 1962 [MF 248]).
