Location: Specimen Gulch is a southwest-flowing seasonal tributary of Anvil Creek. It is below the high-level or bench deposits of the Summit claim (NM247). The map location is at an elevation of about 350 feet at about the midpoint of Specimen Gulch in the south-central part of section 36, T. 10 S., R. 34 W., Kateel River Meridian. The location is locality 48 of Cobb (1972 [MF 463]); it is accurate to within about 500 feet.
Geology: Specimen Gulch heads in the high-bench gravels near the Summit claim (NM247); it also crosses a major east-side bench of Anvil Creek. Both the Summit and Anvil Creek bench placers contributed gold to the shallow deposits in Specimen Gulch (Collier and others, 1908, p. 191; Moffit, 1913, p. 84). In Specimen Gulch, gold occurred throughout an 8-foot section beneath a 1-foot muck layer. The gold was bright, coarse and not well waterworn (Collier and others, 1908, p. 191). In lower Specimen Gulch, bedrock is mainly graphitic schist, possibly between strands of the Anvil Creek fault (Hummel, 1962 [MF 247]). Upper Specimen Gulch is underlain by orthogneiss and metavolcanic schist (Bundtzen and others, 1994). The area has been mined repeatedly from 1899 until the present.
Workings: Extensive surface workings. The area has been mined since 1899.
Age: Quaternary.
