Location: Robin Creek is a west tributary to upper Dominion Creek (BH012), a west tributary to Salmon River. The headwaters of Robin Creek are on the east flank of Mt. Plummer and the north flank of Marvel Dome. This prospect is assumed to be on the lower part of the creek, about 1/2 mile upstream of the confluence with Dominion Creek. The map site is in the SW1/4 of section 34, T 11 N, R 58 W, of the Seward Meridian. Hoare and Cobb (1977) included this locality under the name 'Robin Ck.'.
Geology: Robin Creek is one of the drainages that heads on Marvel Dome, where an Upper Cretaceous granitic stock is surrouded by hornfels in sedimentary rocks of the mid-Cretaceous Kuskokwim Group (Box and others, 1993). Quartz veins, without obvious metallic minerals, are present in bedrock near its head (Maddren, 1915, p. 338). A small glacier occupied the upper part of Robin Creek valley and outwash deposits, including many boulders 1 to 5 feet in diameter, fill the lower part of the valley (Maddren, 1915, p. 338). The outwash deposits are incised by the present stream. Placer claims have been staked on Robin Creek, but the presence of placer gold has not been verified.
Workings: Placer claims have been staked and some exploration is assumed to have taken place on Robin Creek.
Age: Quaternary.
