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 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. War Production Board order L-208, shutting down all nonessential gold mines in the United States.
Buildings at the Log Cabin Mine are amazingly preserved — glass in windows, with lighting fixtures, equipment, and machinery. This large building was the mess hall, perched below Mt. Warren.
Looking across to the headframe and mill — both in surprisingly good shape.
The hoist house and assay shack are adjacent to the headframe, with most of their equipment intact.
Inside the hoist building is a large single-drum hoist — the motor, the electrical equipment and controls, even the operator’s chair, are all still there.
An attractive nuisance if I’ve ever seen one.
A covered conveyor belt.
Looking up, inside the covered conveyor belt.
A sign of caution when approaching the Log Cabin Mine.
Leaving the mine, we crossed Warren Bench which gave us a spectacular view of Mono Lake to the east. That’s Mono Dome (10,469′) behind the truck.
Leaving the mine, we bumped into Caltrans’ “<!a href=”https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwjTu9iy1snPAhUBRmMKHRWoDfQQFggeMAA&url=http%3A%2F%2Fwww.dot.ca.gov%2Fdist6%2Fenvironmental%2Fenvdocs%2Fd9%2Fus395_lee_vinning.pdf&usg=AFQjCNGuW4NKaSmJ88NKeEXFe12yTLbMXw&sig2=8CoBpydl8-3gfMrOzGoT2g” target=”_blank” rel=”noopener noreferrer”>Lee Vining Avalanche Control System” (.pdf) with a pretty amazing view of Mono Lake.
Caltrans: “… permanent propane and oxygen gas explosion chambers (<!a href=”http://www.mountec-corp.com/en/avalanche/gazex” target=”_blank” rel=”noopener noreferrer”>GazEx) at the head of avalanche chutes, approximately 3/4 mile upslope from U.S. Highway 395. The GazEx system consists of exploders mounted in the avalanche starting zones above the highway. The exploders are large tubes, closed at one end, open at the other, with their open ends located above and directed onto the snow. The exploders are filled by remote control with propane and oxygen, then remotely detonated. The shelters contain the remote control system and the oxygen and propane tanks for the system. The operator controls the system from a safe location using a computer linked by radio to the control systems in the shelters. The propane and oxygen tanks would be removed in the spring and replaced in late fall/early winter (October 15-November 1). This would avoid having propane and oxygen gas tanks on the mountain during fire season.”
