Location: Dawson Creek is a short north tributary to the Casadepaga River; it is located across from the mouth of Big Four Creek (SO066). The surface elevation here is about 225 feet. This is locality 70 of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: Dawson Creek heads in Paleozoic marble of Mount Dixon (Till and others, 1986) but its lower reaches cross terraces of the Casadepaga River. Small-scale mining occurred along lower Dawson Creek where bedrock includes micaceous schist (Smith, 1910) and apparently at least some of this mining was of bench gravels that were 8 to 10 feet thick.
Workings: Small-scale suface placer mining occurred between 1900 and 1907 (Cobb, 1978, OF 78-181).
Age: Quaternary; the numerous incised terraces along the Casadepaga River indicate that more than one cycle of erosion and deposition has developed placer deposits in the area. The low elevations from 170 to 270 feet along the first 11 miles of the river, suggest that Quaternary sea level fluctuations could have influenced placer development.
