Location and accuracy Swede Creek (Gulch) is a small, 0.4 mile long drainage that flows south to Norton Sound, 1.7 miles east of Bluff. It is about 0.5 mile east of the center of section 5, T. 11 S., R. 25 W. The location is accurate.

Geologic setting

Geologic description

Placer gold was discovered on Swede Creek between 1900 and 1902 (Collier and others, 1908) but most mining was between 1918 and WW II (Mulligan, 1971). The placer workings were shallow and extended 600 feet upstream from the steep sea cliffs along Norton Sound (Herreid, 1965). The documented gold production from Swede Creek is less than 1,000 ounces but the extent of the workings suggested to Mulligan (1971) that production could have been greater. Bedrock in the area is Paleozoic marble to both sides of a wide band of schist (Herreid, 1965; Mulligan, 1971; Till and others, 1986). Cinnabar was reported in the placer deposits as early as 1922 (Cathcart, 1922) and a lode cinnabar deposit (SO133) was subsequently identified within about a hundred feet of the point that Swede Creek cascades down the almost vertical sea cliffs that are several hundred feet high.
