Atwater Creek Mine, Fortymile District, Southeast Fairbanks Borough, Alaska, USA
Location: 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.

Atwater Creek is locality 89 of Burleigh and Lear (1994).
Geology: Bedrock 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.
