|Location and accuracy||Nevada Creek is a southeast-flowing tributary of Poorman Creek and is approximately 6 miles long. Coordinates are arbitrarily placed at the midpoint of the creek in section 10, T. 16 S., R. 16 E., Kateel River Meridian and correspond to location 37 of Eberlein and others (1977). The location is accurate within 3 miles.|
Geologic descriptionThe headwaters of Nevada Creek are underlain by Tozitna terrane Paleozoic slate, siltstone, chert, graywacke, and limestone in thrust fault contact with Ruby terrane Paleozoic phyllite and quartzite (Puchner and others, 1998). Good placer gold prospects were reported during the winter of 1930-1931. There are no later reports of mining (Smith, 1933).
