Tumco

Pete Walters of Ogilby discovered the first gold vein at Gold Rock on January 6, 1884. From his Little Mary Claim began a gold camp which reached its peak development between 1893 and 1899 as Hedges, with 3,200 residents. Nearly closed, 1900-10, it was reopened as Tumco, 1910-13, and worked intermittently until 1941. Tumco has long been a California ghost town.

Plaque placed by the State Department of Parks and Recreation in cooperation with Imperial Valley Pioneers Historical Society and Squibob Chapter, E Clampus Vitus. October 19, 1985.
