|Location and accuracy||Nugget Creek is a northeast-flowing tributary of Washington Creek and is about 3.5 miles long. The coordinates are for the main area of placer activity, in section 18, T. 4 N., R. 27 E., of the Fairbanks Meridian. The location is accurate. This creek lies within Doyon, Limited selected or conveyed land.|
The bedrock in the Nugget Creek drainage is Lower Cambrian to Middle Proterozoic Tindir Group rocks of varying sedimentary lithologies and abrupt facies changes (Dover and Miyaoka, 1988). The gold in Nugget Creek occurs as local accumulations of coarse gold on Cambrian argillite bedrock (National Park Service, 1990).Production for Nugget Creek through 1938 was 1,772 troy ounces of gold and 302 troy ounces of silver. The largest reported nugget was a little larger than 8 ounces (National Park Service, 1990).
