|Location and accuracy||Eldorado Creek is approximately 4 1/2 miles long and is a southeast-flowing tributary of Poorman Creek. Exact location of the prospect is unknown however; the coordinates used correspond to location 16 of Eberlein and others (1977). The site is marked at the approximate midpoint of the stream, in section 16, T. 16 S., R. 16 E., Kateel River Meridian. The location is accurate within 2.5 miles.|
Geologic descriptionThe upper part of Eldorado Creek is underlain by Paleozoic phyllite and quartzite (Puchner and others, 1998). Good gold prospects were reported along the creek in 1930 and 1931, but there is no later mention of any further development (Smith, 1933; Eberlein and others, 1977; Cobb and Chapman, 1981).
