London Mine and Mill Complex

-A A +A
1931–1980s. 1 mile south of Alma, turn right on U.S. Forest Servide Rd. 438 (Mosquito Pass)

The old mining town of Park City lies one mile up this dirt road. A mile farther west, the London complex stretches for several miles along the road and Mosquito Creek. The North and South London Mines, opened in 1883, were connected to the railroad spur up Mosquito Creek by a 4,500-foot aerial tramway, remnants of which can still be seen. Production of 100 tons per day justified a custom gold mill, which operated into the 1980s. The rough, four-wheel-drive road to Leadville over 13,186-foot Mosquito Pass meanders through many other mining ruins.
