Geologic setting

Geologic description

A little placer mining took place along McAdam Creek in the 1930s (Moffit, 1933; Smith, 1933 [B 836-A]). Several types of bedrock have been mapped along Adam Creek. The headwater section drains an area underlain by the Moose Creek Member of the Totalanika Schist, which is composed of yellow quartz-orthoclase gneiss and schist; the Suntrana Formation, which is composed of poorly consolidated shale; and the California Creek Member of the Totatlanika Schist, which is composed of gray quartz-orthoclase-sericite schist and augen gneiss (Wahrhaftig, 1970 [GQ-810]). The mine area itself is underlain by a Miocene coal-bearing unit (Wahrhaftig, 1970 [GQ-810]).
