Alta, Colorado

Alta is a historical ghost town located in San Miguel County, Colorado, United States. Alta was established in 1877 as a mining settlement, and became an important site for gold and silver extraction during the Colorado Silver Boom. The site is notable for being one of the earliest places in the world to use Nikola Tesla's AC transmission system to power mills in its area. Alta was abandoned in 1948 when a fire engulfed the mine complex and ceased its function as an active mining site.
