Geologic information

Identification information

Deposit ID 10307248
Record type Site
Current site name Cripple Creek (upper)

Geographic coordinates

Geographic coordinates: -159.5428, 60.70933 (WGS84)
Relative position Cripple Creek is a southeast headwater tributary of the Salmon River. This placer mine is one of two locations given by Cobb (1972 [MF 455]) on Cripple Creek. It is along about 11/4 mile of the upper creek above the mouth of Loco Creek, a southwest tributary to Cripple Creek. The map site is at the approximate midpoint of the placer, in the SE1/4 of section 7, T 7 N, R 58 W, of the Seward Meridian. This is locality 17 of Cobb (1972 [MF 455]) and of Hoare and Cobb (1977).

Comments on the geologic information

  • Geologic Description = Cripple Creek was prospected and staked soon after placer gold was discovered on Marvel Creek (BH010) in 1911. The headwaters of Cripple Creek have coarse outwash or morainal deposits, and a glacier occupied the headwater valley of Loco Creek, a west tributary. Most of the Cripple Creek drainage is filled with alluvial outwash deposits. These have been incised by the present drainage that cuts 10 to 30 feet into bedrock along the lower reaches of the creek. Placer mining along Cripple Creek above the mouth of Loco Creek, has taken place over at least a mile of the creek and seems restricted to the active flood plain (Cobb, 1972 [MF 455]). The flood plain gravels are about 6 feet thick and some of the pay is reported to have run about 0.003 ounce of gold per cubic yard (Hoare and Cobb, 1977, p. 9). The gold is fine and flaky and accompanied by much magnetite. Bedrock in the headwaters of Cripple Creek and Loco Creek include a Lower Tertiary granitic stock and a rhyolite intrusive (?) in mid-Cretaceous sedimentary rocks of the Kuskokwim Group (Box and others, 1993).
  • Age = Quaternary.

Comments on the workings information

  • Workings / Exploration = Cobb (1972 [MF 455]) shows that over a mile of the active flood plain has been placer mined in this area.
