Geologic setting

Geologic description

At this site placer gold has been found in beach deposits as well as in sand dunes derived from the beach sands. Magnetite is fairly abundant in the dunes as well as on the beach. Gassaway (1935, p. 4) reports black sand layers on the beach to be up to 2 feet in thickness with a gold content of less than commercial grade. The gold was reported to be extremely fine and difficult to amalgamate. The immediate source of the placer gold is thought to be the nearby bluffs of glacial gravels and tills.

Production and reserves

Workings or exploration As reported by Capps (1937), in 1935 a mill was under construction to treat the wind-blown dune sand for its gold content. No further efforts were reported and the endeavor was apparently not successful. At this same time some mining of the beach deposits was being carried out with sluice boxes and amalgamation plates.
Indication of production Yes; small
