Location: Ridgeway Creek is a south tributary of Lower Willow Creek (SO091). Its mouth is 2 miles upstream from the mouth of Lower Willow Creek on the Casadepaga River. This is locality 77 of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: The lower mile of Ridgeway Creek carries gold, including small nuggets (Smith, 1910), but mining has not been reported (Cobb, 1978, 78-191). The regional contact between pelitic schist of possible Cambrian or Precambrian age and a lower Paleozoic metasedimentary assemblage passes through the headwaters of Ridgeway Creek (Till and others, 1986).
Workings: Prospecting was done on Ridgeway Creek prior to WW I but the unavailability of water was a handicap to early mining and none has been reported.
Age: Quaternary; the numerous incised terraces along the Casadepaga River and its major tributaries (including Lower Willow Creek) indicate that more than one cycle of erosion and deposition has developed placer deposits in the area. The low elevations between 170 and 270 feet along the first 11 miles of the river, suggest that Quaternary sea level fluctuations could have influenced placer development.
