Location and accuracy There are unconfirmed reports of placer gold along the Unalakleet River. The precise location of any prospecting is unknown. It is likely to be in the Norton Bay quadrangle, although it may be in the Unalakleet quadrangle. For this record, the site is arbitrarily plotted at the approximate midpoint of the Unalakleet River in the Norton Bay quadrangle. The location is accurate within 25 miles.

Geologic setting

Geologic description

The rocks in the vicinity of the Unalakleet River consist mostly of graywacke, shale, grit, and conglomerate of the Cretaceous Shaktolik Group (Cass, 1959). An intrusive body of unspecified composition is located approximately 5 miles south of the river and 7 miles south of the boundary of Holy Cross quadrangle; it is partially buried by sediments from the river (Cass, 1959). Schrader and Brooks (1900) report gold discoveries along the Unalakleet River during the fall of 1898, but there are no more recent reports of gold there.
