The Log Cabin Mine is located at 9,600‘ in the Eastern Sierra Nevadas above the town of Lee Vining. The state-of-the-art mine was opened in 1910 and could extract and process the gold from the quartz ore, making it one of the highest-producing mines in California. The mine operated for around 30 years but was closed due to the War Production Board order L-208, shutting down all nonessential gold mines in the United States. An attempt was made to reopen the mine in the 1950s but was not successful. In 1971, the mine was turned over to the government and is currently preserved as a historical site. Today, the mine is flooded around 200 feet below the surface.
