Location and accuracy Cahill Creek is a north tributary to Lower Willow Creek. Its mouth is at an elevation of about 500 feet, 3.3 miles upstream of the confluence of Lower Willow Creek and the Casadepaga River. This is locality 75 of Cobb (1972, MF 445; 1978, OF 78-181).

Geologic setting

Geologic description

Cahill Creek has been prospected and gold was found along the lower 0.5 mile where the creek crosses benches of Lower Willow Creek (Smith, 1910).
Geologic map unit (-164.454619850326, 64.8182571384161)
Mineral deposit model Placer Au-PGE (Cox and Singer, 1986; model 39a).
Mineral deposit model number 39a
Age of mineralization 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.
