Location and accuracy Otter Creek is the first west tributary to Nome River upstream from its mouth on Norton Sound. About 3,500 feet of lower Otter Creek and the lower 1,000 feet of Florence Gulch, an east tributary to Otter Creek, have been placer mined. This placer mining is at elevations of less than 25 feet; its downstream limit is about at the projected Second Beach crossing of the Nome River drainage. The map location is on Otter Creek just below the mouth of Florence Gulch, in the NW1/4 section 33, T. 11 S., R. 33 W., Kateel River Meridian. It is locality 124 of Cobb (1972 [MF 463], 1978 [OFR 78-93]).
