|Location and accuracy||Spangle Creek is a 2 1/2-mile-long, east-flowing tributary of the Sulatna River. Coordinates corresponding to location 44 of Eberlein and others (1977) mark the approximate center of prospecting on Spangle Creek, in section 21, T. 15 S., R. 17 E., Kateel River Meridian. The location is accurate within 1 mile.|
Geologic descriptionThe headwaters of Spangle Creek are underlain by Ruby terrane phyllite and schist; bedrock downstream is obscured by surficial deposits (Puchner and others, 1998). Spangle Creek was unsuccessfully prospected from 1913 through 1915. This drainage basin and the adjacent area are heavily vegetated (Mertie and Harrington, 1916; Cobb and Chapman, 1981) and may not have been adequately prospected (Eberlein and others, 1977).
