|Location and accuracy||Richter Creek is a southwest tributary to the Niukluk River. The mouth of Richter Creek is 1.2 miles upstream of the mouth of Ophir Creek (SO053). This is locality 118 of Cobb (1972, MF 445; 1978, OF 78-181).|
Geologic descriptionSome small-scale mining apparently took place along this creek in the early history of the area. The gold placers were reported to be nearly exhausted in 1906 (Smith, 1907). Bedrock in the area is part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
