This site is within the Yukon-Charley Rivers National Preserve.
Location: Sawyer Creek, not named on the current (1956, revised 1974) topographic map of the Charley River quadrangle, is a north-flowing tributary to Sam Creek, about 10 miles from its confluence with the Yukon River. Sawyer Gulch is location 6 of Cobb (1972 [MF-390]). The placer mining was in section 19, T. 5 N., R. 23 E., of the Fairbanks Meridian. The location is accurate within one mile.
Geology: A small placer deposit was reported in the early 1900s on a tributary, presumably Sawyer Creek, of Sam Creek (CY027). The gold, as in other nearby placer deposits, is likely derived from the Cretaceous to Tertiary conglomerate that underlies the creek (Mertie, 1942; Dover and Miyaoka, 1988).
Workings: A small placer deposit was reported in the early 1900s on Sawyer Creek. The general area was mined and explored extensively prior to World War II (Mertie, 1942).
Age: Quaternary.
Commodities (Major) - Au
