Unpopulated Places
Caribou, Colorado was an important silver mining town. Famed at the time for being the coldest, snowiest, windiest town, at 10,000 feet elevation it was not an easy place to live. The Silver Crash of 1893 meant that it was less profitable. Incorporated as a town in 1871, Caribou had peak population of 549 in the 1880 census, and became a ghost town by the 1920s.

Many mining communities have formed and disbanded in this area, including Wall Street, Tungsten, Summerville, Rowena, Marshall and Magnolia.
