|Location and accuracy||Puckmummie Creek is a small creek that drains north to the Casadepaga River. Its mouth is about 0.5 miles upstream of the confluence of the Casadepaga and Niukluk Rivers. This is locality 71 of Cobb (1972, MF 445; 1978, OF 78-181).|
Geologic descriptionGold colors are widely distributed in thin gravel, 2 to 3 feet thick, but there is no record of mining on the creek (Smith, 1910; Cobb, 1978, OF 78-181). The gravels are derived from bedrock of the drainage which is part of a pelitic schist assemblage inferred to be of Cambrian or Precambrian age (Till and others, 1986).
