A Au-Ag placer deposit in the gulch that heads about 1 mile NE of Greaterville. Owned at times, or in part, or in places by the Stetson Co.; the El Oro Mining Co.; and the Greaterville Dredge Gold Mining Co.
Mineralization is mostly coarse flake and nugget gold with minor combined silver and some attached galena in medium-sized gravel along recent and older buried channels and terraces close to the mountain front. Workable gravels were found in the upper 3,000 feet of its course.
Major operations were undertaken from 1875 to the early 1900's and small and sporadic since then. Estimated production for the entire area is some 30,000 oz. of gold, or more, with about 6,000 oz. of silver.
