|Location and accuracy||Alder Creek is an east tributary to Gold Run who's mouth is 1.9 miles upstream of the confluence of Gold Run and Bluestone River. The old mining facilities of Sullivan's Camp are at the mouth of Alder Creek, 0.25 miles east of the Nome-Teller road. Gold mining reportedly took place along the lower main drainage for about a mile upstream from the mouth on Gold Run. Alder Creek was included as a part of locality 81 by Cobb and Sainsbury (1972). Cobb (1975) summarized relevant references under the name 'Alder Cr.'.|
Geologic descriptionBedrock in the Alder Creek drainage is a chlorite schist assemblage with local metamorphosed mafic intrusive bodies (Sainsbury, 1972). The age of this assemblage is not known but it is probably Paleozoic. Gold was discovered in 1900 and about one mile of the lower creek was reported to have been mined by 1908 (Collier and others, 1908). The gravel is reported to be 4 feet thick over broken limestone bedrock 0.5 miles upstream of the mouth (Collier and others, 1908, p. 279-280). The muck here was also four feet thick. The coarse gold is well-rounded and accompanied by pyrite cubes in heavy mineral concentrates.
