Tenderfoot Creek has a similar setting to deposits on Poorman Creek (RB048), Duncan Creek (RB056) and Little Pup (RB054).
Location: Tenderfoot Creek is a west-flowing tributary of Poorman Creek. The site coordinates given are upstream on the Little Pup Gulch from location 30 of Cobb (1972 [MF405]). The coordinates fall in the NE1/4 section 20, T. 16 S., R. 17 E., Kateel River Meridian. The location is accurate to within a quarter mile.
Geology: The bedrock near the mouth of Tenderfoot Creek is phyllite (Eberlein and others, 1977). Placer ground was discovered along the creek in 1913 (Brooks, 1914). Mining occurred about 1/2 mile above the mouth. The gold was found in a gravel layer 3 to 6 feet thick overlying bedrock and buried by 53 to 65 feet of muck (Eakin, 1914 [B592-J]). Most of the gold is fine, shotty, and water worn (Eakin, 1914 [B592-J]; Eberlein and others, 1977). The gravels of Tenderfoot Creek are difficult to distinguish from the right-limit gravels of Poorman Creek (Eberlein and others, 1977). Mining along Tenderfoot Creek may be in gravels of Poorman Creek that are cut by Tenderfoot Creek (Eberlein and others, 1977). Mining occurred intermittently into the 1930's (Smith, 1939 [B917-A]).
Workings: Tenderfoot Creek experienced mining from 1913 to at least the 1930's (Eberlein and others, 1977).
Age: Quaternary.
