This small lode-gold district is in northern Del Norte County about 45 miles northeast of Crescent City. Most of the work here has been done at the Monumental Consolidated mine, which has been intermittently developed since about 1900. Several quartz veins in greenstone and slate contain some gold, pyrite, chalcopyrite, and hematite. The greatest depth attained here is about 250 feet.
