Comments on the geologic information

  • Geologic Description = The upper part of the valley of Roosevelt Creek is eroded in thick Nenana Gravel, but the lower part of the valley is eroded to a depth of 100 feet or more into interbedded clay, sand, gravel, and coal of the Tertiary Grubstake Formation (Wahrhaftig, 1970 [GQ-809]). Gold is found in the basal 2 feet of stream gravel (Maddren, 1918, p. 400). Placer gold in the creek is fine, flat, and well-worn (Prindle, 1907, p. 210-211). Mining was reported in 1910 and 1916 (Capps, 1912, p. 44; Maddren, 1918, p. 399).
  • Age = Quaternary placer.
