Location: Short Creek is a 2-mile-long northwest-flowing tributary of Long Creek. Placer deposits extend about 1 1/2 miles from the head of Short Creek down to the winter trail marked on the Ruby (B-6) Quadrangle (USGS topographic map, 1952). Coordinates given correspond to location 15 of Cobb (1972 [MF405]), and mark the approximate midpoint of the mined area in section 17, T. 13 S., R. 17 E. of the Kateel River meridian. The location is accurate.
Geology: The bedrock underlying the head of Short Creek is intermediate to mafic intrusive rocks, probably greenstone (Puchner and others, 1998). At the winter trail crossing of Short Creek there is 4 to 6 feet of gravel beneath 6 to 8 feet of muck, and the depth to bedrock increases to 75 feet at the mouth of the creek (Mertie and Harrington, 1916; Chapman and others, 1963). The most gold is usually found within a foot of bedrock in an irregular and poorly defined channel (Mertie and Harrington, 1916). The gold is accompanied by cassiterite, and a few thousand pounds of cassiterite were recovered as byproduct in 1918 (Chapin, 1919). The creek was mined using open-pit methods in 1914 and 1915 (Mertie and Harrington, 1916). The placer ground was worked 10 to 15 feet deep over a width of 20 to 40 feet for a distance of 1 to 1 1/2 miles (Eberlein and others, 1977). Mining may have extended into the early 1920s, but there are no records of more recent activity (Eberlein and others, 1977).
Workings: Short Creek experienced open-pit mining during 1914 and 1915 and probably into the early 1920s (Mertie and Harrington, 1916).
Age: Quaternary.
Production: The gold is accompanied by cassiterite, and a few thousand pounds of cassiterite were recovered as byproduct in 1918 (Chapin, 1919).
