Comments on the geologic information

  • Geologic Description = Gold-bearing bench gravel E of Crooked Creek is 20 ft (6 m) above present stream, 1 mi (1.6 km) wide, and 10-100 ft (3-30.5 m) deep to bedrock. Gold is reconcentrated along tributary streams flowing through benches. Only a few short, narrow paystreaks, alternating with low-grade or barren gravel, in streams. Only 1 mi (1.6 km) of placer deposit is in Sleetmute quad; the rest is in the Iditarod quadrangle.
  • Age = Tertiary/Quaternary
