Location: This occurrence is on the modern beach along the west shore of Togiak Bay, 4 miles north of Tongue Point. It is locality 20 of Cobb (1972 [MF 362]; 1980 [OF 80-909]).
Geology: 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.
Workings: There are no workings at this locality, although Berryhill (1963) noted several old hand-dug trenches at Tongue Point.
Age: Holocene.
