|Location and accuracy||Cobb (1972, MF-410), loc. 68; The McAdam Creek mine is located in the NE1/4 sec. 22, T. 10 S., R. 6 W., Fairbanks Meridian. McAdam Creek is a northwest-flowing tributary of California Creek about 9 miles southeast of Rex Dome. Placer mining has taken place along the lower one-half mile of the creek. The mine is locality 68 of Cobb (1972 [MF 410]).|
Geologic descriptionA 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]).
