Identification information

Deposit ID 10002457
MRDS ID A013387
Record type Site
Current site name Tuluksak River (below Granite Creek)

Geographic coordinates

Geographic coordinates: -160.15283, 60.96932 (WGS84)
Relative position In the original reference to this placer prospect on Tuluksak River, Maddren (1915) located it 5 miles downstream from the mouth of Granite Creek (BH015). For this record, however, it is assumed to be at a cabin and trailhead, about 3 miles downstream from the mouth of Granite Creek. The map site is at the southwest corner of section 7, T 10 N, R 61 W, of the Seward Meridian. This is locality 9 of Cobb (1972 [MF 455]) and of Hoare and Cobb (1977).

Comments on the geologic information

  • Geologic Description = Maddren (1915) reported that fine gold was found in a 50-foot prospect shaft that was dug in frozen ground on this part of the Tuluksak River. This prospect is on the lower part of the river, where the gradient decreases and it enters onto the lowlands of the lower Kuskokwim River. The low elevation and proximity to the Kuskokwim River lowlands suggests that Quaternary sea level fluctuations could have influenced placer development on the lower Tuluksak River.
  • Age = Quaternary.
