Geographic coordinates

Geographic coordinates: -160.09283, 60.97932 (WGS84)
Relative position Granite Creek is a short north tributary to Tuluksak River (BH014). The mouth of Granite Creek, at an elevation of about 350 feet, is 3 miles upstream from the lowlands of the lower Kuskokwim River. Placer mine tailings are present along about 3/4 mile of lower Granite Creek. The map site is at the approximate midpoint of the placer workings, at the southwest corner of section 3, T 10 N, R 61 W, of the Seward Meridian. This is locality 10 of Cobb (1972 [MF 455]) and of Hoare and Cobb (1977).

Comments on the geologic information

  • Geologic Description = About 3/4 mile of lower Granite Creek has been placer mined for gold. Most of the Granite Creek drainage is within a mid-Cretaceous granitic pluton but the lower part crosses the contact with hornfels in Jurassic volcanic rocks (Box and others, 1993). Mining took place in 1938-1940 and in 1946 but additional information about the placer deposit is not available (Hoare and Cobb, 1977).
  • Age = Quaternary.
