Location: Lightning Creek is a small south tributary to the Casadepaga River. Its mouth is about 2.5 miles upstream from the mouth of Big Four Creek. This is locality 62 of Cobb (1972, MF 445; 1978, OF 78-181).
Geology: Smith (1910) noted that considerable prospecting had occurred by 1907 along the active drainage of lower Lightning Creek where it crosses terraces of the Casadepaga River. The terrace gravels here are 5 to 10 feet above the active stream. Bedrock in the area is primarily part of a lower Paleozoic metasedimentary assemblage (Till and others, 1986).
Workings: Surface prospecting pits were dug along the active stream in about 1907.
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 between 170 and 270 feet along the first 11 miles of the river, suggest that Quaternary sea level fluctuations could have influenced placer development.
Commodities (Major) - Au
Development Status: Undetermined.
