Comments on the geologic information

  • Geologic Description = Maddren (1915, p. 358) reported that one man was recovering gold with a rocker on the Togiak Bay beach during 1914. Berryhill (1963, sample 86) collected beach samples along the west side of Togiak Bay and reported flour gold in heavy-mineral concentrate from this locality. The beach is a thin veneer of sand below a 40-foot-high bluff of glaciofluvial gravels that are considered to be the source of the gold.
  • Age = Holocene.
