Location and accuracy This alluvial gold placer mine is on Moss Gulch, a small east tributary to lower Nome River. Some small-scale placer mining appears to have taken place along about 1,000 feet of the creek at surface elevations of less than 50 feet. The map location is in the NE1/4 section 26, T. 11 S., R. 33 W., Kateel River Meridian. Moss Gulch is locality 122 of Cobb (1972 [MF 463], 1978 [OFR 78-93]).

Geologic setting

Geologic description

Placer mining for gold took place at a surface elevation of about 50 feet on lower Moss Gulch by dredging in 1911 and by open-cut in 1916 (Smith, 1912; Mertie, 1918 [B 662-I, p. 425-449]). Mining may have occurred at other times as well, but it has not been reported. The headwaters of Moss Gulch are at elevations and physiographic settings where coastal plain deposits could be present. The Moss Gulch deposit probably formed at least in part from reworking a weakly developed Third Beach (Metcalfe and Tuck, 1942).
