Conflicting references to Flat Creek may be describing the Flat Creek (RB051) that is a tributary to Timber Creek (RB049).
Location: Flat Creek, a southwest-flowing tributary of Long Creek, is about 8 miles long. The coordinates given correspond to location 21 of Cobb (1972; MF-405), and location 18 of Eberlein and others (1977). The site marks the approximate location of prospect pits located 1/4 mile upstream from the winter trail crossing, in section 30, T. 13 S., R. 17 E. of the Kateel River meridian. The location is accurate.
Geology: The bedrock underlying the head of Flat Creek, a tributary of Long Creek, is Paleozoic schist and other metamorphic rocks (Puchner and others, 1998). Flat Creek cuts benches of Long Creek near its mouth. Small amounts of gold and cassiterite were reported in prospect holes in 1938; however, neither was found in dump samples in 1942. The mining may have been in nearby bench gravels of Long Creek. There is some discrepancy about when this creek was prospected or mined: Smith reported mining along Flat Creek from 1929 until 1940, but Chapman and others (1963) state that there was very little mining along the creek until 1942, and none between 1942 and 1960. The confusion may be the result of poor discrimination between this Flat Creek and another Flat Creek (RB051), a tributary of Timber Creek (RB049) near Poorman. During the early 1980s, Resource Associates of Alaska drilled two lines across Flat Creek to test the gravels for placer gold (Jim Johnson, oral communication, 2000).
Workings: Mining along Flat Creek was reported from 1929 until 1940, but other reports say there was very little mining during this time (Eberlein and others, 1977). There may be confusion with a different Flat Creek (RB051), that is a tributary to Timber Creek (RB049). During the early 1980s, Resource Associates of Alaska drilled two lines across Flat Creek (Jim Johnson, oral communication, 2000).
