Geographic coordinates

Geographic coordinates: -151.86647, 59.76752 (WGS84)
Relative position Cobb (1972, MF-397) located this placer occurrence as begining at the south end of the spit at the mouth of Anchor River and running south along the beach for a mile and a half. This is Cobb's (1972, MF-397) location 2, and is accurate to within one quarter of a mile. There has apparently been no commercial mining at the site since before World War I.

Comments on the geologic information

  • Geologic Description = Gold has been found along the shoreline in a thin gravel layer about two feet below the surface. This area was mined intermittently from 1889 to 1911, mostly by rocker and small sluice boxes. One hydraulic plant was installed prior to 1906 (Moffit, 1906, p. 44) but it was a failure. The gold is probably derived from the Kenai Formation.
  • Age = Quaternary.

Comments on the workings information

  • Workings / Exploration = This area was mined intermittently from 1889 to 1911, mostly by rocker and small sluice boxes. One hydraulic plant was installed prior to 1906 (Moffit, 1906, p. 44) but it was a failure. In support of the hydraulic plant a two mile long ditch and several support structures were built at the turn of the century.
