Location and accuracy Center Creek Beach is an irregular, buried, east-west gold placer deposit at elevations ranging from 10 feet above to 10 feet below sea level. It appears to extend as far west as Little Creek and as far east as Peluk Creek and is about half way between Submarine and Intermediate Beaches. The map location is at the south-central edge of section 23, T. 11 S., R. 34 W., Kateel River Meridian; it is located within about 1,000 feet.

Geologic setting

Geologic description

The Center Creek Beach deposit is a rather diffuse, east-west aligned, marine concentration of placer gold about half way from the mouth of Center Creek to Intermediate Beach. The deposit extends along the coastal plain between Little Creek and Peluk Creek (Metcalfe and Tuck, 1942, p. 36). The deposit is developed on schist bedrock, and it is at elevations of -10 to +10 feet relative to sea level. It probably is an eroded beachline lowered by abrasion of the marine platform. The part of the deposit immediately east of the north-south runway at Nome airport was dredged. The deposit was subsequently developed in 1995-98 by an open-cut operations. It was mined during the winter, and the gravel was washed in the summer. Bedrock exposed in the pit is micaceous schist that locally contains some quartz-ankerite-albite veins.
