Dolores County Gold Panning

Gold Mining Site CO • Dolores County County
Description
Practically all of the 104,500 ounces of gold produced in Delores County came as a by product from lead, silver and zinc mines, so it is not an important county for the recreational prospector. Although one may be able to find some placer in the headwaters of the Dolores River, south of Rico.
