Lake Emma is a secluded retreat at an elevation of 3.809m (12,496ft) above the sea level, located in San Juan County, Colorado, in USA. It’s one of the highest mountain roads of Colorado.
The road to the lake, nestled amongst the highest mountains in South Park, is called County Road 25 (Sunnyside Mine Road). This road can be done with a passenger car, but it can be very rugged and rutted after a hard winter. In the winter of 1977 the water from the lake began to leak into the mine that was still being worked. Then, on a Sunday in June, the entire lake flooded into the mine. Lake Emma was gone and the mine was destroyed. Luckily, no one was inside at the time. It's an old mine road.
