|Location and accuracy||This alluvial placer gold mine is on Grass Creek, a small west tributary to Saunders Creek (NM307). The mouth of Grass Creek is about 1.8 miles upstream of the Nome-Council road crossing of Hastings Creek. About 3,000 feet of lower Grass Creek has been placer mined. This location is the approximate midpoint of the placer workings, in the NE1/4 section 5, T. 12 S., R. 32 W., Kateel River Meridian. It is included in locality 133 of Cobb (1972 [MF 463], 1978 [OFR 78-93]).|
Geologic descriptionPlacer gold tailings are present along the lower 3,000 feet of Grass Creek. It was probably mined at about the same time and by the same methods as Saunders Creek (NM307), dredged in 1911-1912. Grass Creek primarily flows across older parts of the Nome coastal plain. Judged from the elevation at the head of pay (about 75 feet), the gold in Grass Gulch could be derived from Third Beach, which in this area appears to have been developed on offshore bars and lagoons (Metcalfe and Tuck, 1942).
