Location: This placer gold prospect on an unnamed, northeast-flowing creek that drains into the lake in Caribou Pass, at the head of Middle Fork Chulitna River. The placer deposit extends for a distance of about a mile upstream from the map site, which is in the SW1/4 of sec. 23, T. 19 S., R. 7 W., of the Fairbanks Meridian. This is location D-2 of Balen (1990: OFR 34-90).
Geology: The drainage area of the creek containing the Caribou gold placer prospect is underlain by Cretaceous or Jurassic turbidites and Lower Tertiary volcanic rocks (Wilson and others, 1998). A single sample of the placer contained 300 ppb gold and 8 ppm tin (Balen, 1990: OFR 34-90). The source of the placer gold and the tin is unknown.
Workings: There have only been surface workings to date.
Age: Quaternary.
