|Location and accuracy||There is small area of placer mine tailings along the north bank of Snake River at this location, about 0.4 mile upstream of the Nome airport. This is locality 130 of Cobb (1972 [MF 463], 1978 [OFR 78-93]). The map location is just inside the west-central edge of section 21, T. 11 S., R. 34 W., Kateel River Meridian. The location is accurate to within about one-third mile.|
Geologic descriptionFine gold was discovered on the bars of lower Snake River in 1898 (Schrader and Brooks, 1900). This location was plotted separately by Cobb (1972 [MF 463]) and some placer tailings appear to be present. Dredge operations took place on lower Snake River between 1919 and 1924 (Cobb, 1978 [OFR 78-9]). At least some of the dredge operations were part of a harbor-deeping project, and gold recovery was incidental. This part of Snake River reworks coastal plain deposits, and some richer gold concentrations may at least locally be present.
