This is a small gold- and tungsten-mining district in northwestern Alpine County about 10 miles west of Markleeville. The area was first prospected during the early 1860s, followed by minor intermittent prospecting and development since. Some tungsten was produced during World War II and the Korean War.
The ore deposits are associated with two northtrending roof pendants of hornfels, quartzite, and schist that are surrounded by granodiorite. The deposits consist of narrow gold-quartz veins and pyrite and tungsten-bearing garnetiferous tactite. Small amounts of copper also are present.
