Comments on the geologic information

  • Geologic Description = The Windy Creek deposit consists of 40 to 60 feet of gravel with the lower 6 feet stained and cemented by iron oxides and hydroxides, overlain by glacial mud containing large angular boulders. Gold occurs in the lower iron-stained 6 feet. The gravel averages 5 inches in diameter with some boulders from 1 to 3 feet in diameter. Glacial mud layer is overlain by 20 feet of gravel containing abundant pyrite (Capps, 1913; C.C. Hawley and Associates, Inc., 1978). Concentrates contain arsenopyrite, cassiterite, native copper, gold, ilmenite, magnetite, pyrite, scheelite, garnet, quartz and zircon (Cobb and Reed, 1980). This deposit appears to be of glaciofluvial origin, similar to Nugget (TL035) and Bird Creek (TL040) placers. See also Cache Creek (TL029).
  • Age = Pleistocene.
