Location and accuracy Cobb (1972, MF-413), loc. 88; SW1/4 sec. 2, T. 3 N., R. 2 E., of the Fairbanks Meridian. This location is on the tailings along the bench gravels on the west side of the Steese Highway, opposite the village of Chatanika. This location is the approximate center of several miles of placer mined ground along the Chatanika River.

Geologic setting

Geologic description

Bedrock is schist and the gravel is largely quartzite, igneous rocks and vein quartz. Depth to bedrock (measured on 5 claims) was from 75 to 125 feet (Prindle and Katz, 1913, p. 107). Most mining was at and below the mouth of Cleary Creek and near the mouths of Dome and Vault Creeks. Placers are about 65 to 200 feet deep at the mouths of Dome and Vault Creeks (Mulligan, 1974, p. 11). From 1911 to 1927 all mining was from drift mines, and dredging began near the mouth of Cleary Creek in 1928. USSR&M dredge no. 3 worked on the Chatanika from 1928 to 1942, and from 1946 to 1963 (R.M. Chapman, USGS unpublished memorandum, 1978). Production from 1907 to 1910 was 70,658 ounces of gold (Prindle and Katz, 1913). Gold assayed at 852 fine.
