Comments on the geologic information

  • Geologic Description = A high-level (bench) gold placer was discovered and probably mined as recently as the 1960,s. The claims were surveyed for patent in 1976, and two were patented in 1977. The main placer pit is excavated subparallel to a south-trending gulch into Glacier Creek; it is on the Judy Bench. Numerous pits were excavated on the upper Deb Bench claim where there are sparsely scattered, rounded granitic boulders. Most of the production from the mine was from the lower Judy Bench, but exploration cuts and granitic boulders are found at least to about 650 feet elevation, similar to some of the high-level benches near Dexter (NM246, NM247, and NM248). The origin of the high-level bench placers is uncertain, but they predate, and furnished placer gold to, younger alluvial placers such as Glacier Creek (NM220) and Anvil Creek (NM236).
  • Age = Probably Pleistocene; possibly Tertiary.
