Comments on the geologic information

  • Geologic Description = Dredging was reported to have taken place 3 miles above the mouth (Chapin, 1913); the gravels here were 2 to 15 feet thick on a clay false bedrock. One mile above the mouth, gravels were 7 feet thick and the pay was in the lower 3 feet. Mud Creek, a headwater tributary of Mystery Creek, contained coarse, rough gold in 3 to 4 feet of angular schist gravel and in 3 to 4 foot-deep crevices in schist bedrock (Collier and others, 1908). Mud Creek gravels were overlain by 2.5 feet of muck and sthe recovered gold was coarse, very rough, spongy, and somewhat rusty. Bedrock is calcareous mica schist with small quartz stringers (Collier and others, 1908); impure schistose Ordovician marble occurs in headwater parts of the area (Till and others, 1986).
  • Age = Quaternary.
