|Location and accuracy||Atwater Creek is a small south tributary stream on the southeast side of the South Fork of the Fortymile River about 4.5 miles east-southeast of Chicken. Although there is a winter trail along Atwater Creek, placer mining likely occurred only at the mouth of the creek, in about the middle of section 12, T. 26 N., R. 18 E., of the Copper River Meridian. Atwater Creek is locality 89 of Burleigh and Lear (1994).|
Geologic descriptionBedrock along Atwater Creek consists of Paleozoic greenschist-facies metavolcanic and metasedimentary rocks, which are in high-angle fault contact with the Taylor Mountain batholith of Triassic age (Foster, 1976; Werdon and others, 2001). Bundtzen and others (1990) reported placer mining occurred on Atwater Creek in 1989.
