San Miguel County is a county located in the U.S. state of Colorado. As of the 2020 census, the population was 8,072. The county seat is Telluride.[2] The county is named for the San Miguel River.
San Miguel County was given the Spanish language name for "Saint Michael" due to the nearby San Miguel River. On February 27, 1883, Ouray County was split to form San Miguel County. Originally the San Miguel County portion was to retain the name Ouray County with the new portion called Uncompahgre County.
Mining operators in the San Juan mountain area of Colorado formed the San Juan District Mining Association (SJDMA) in 1903, as a direct result of a Western Federation of Miners proposal to the Telluride Mining Association for the eight-hour day, which had been approved in a referendum by 72 percent of Colorado voters.[3] The new association consolidated the power of thirty-six mining properties in San Miguel, Ouray, and San Juan counties.[4] The SJDMA refused to consider any reduction in hours or increase in wages, helping to provoke a bitter strike.
In 1875, the Smuggler gold vein was discovered near Telluride. The Smuggler-Union, Tomboy, and Liberty Bell mines combined produced over a hundred tons of gold by 1920, third in the state of Colorado.[5]
According to the U.S. Census Bureau, the county has a total area of, of which is land and (0.2%) is water.[6]
For most of the 20th century, San Miguel County was a national bellwether. It voted for the winner in every presidential election from 1912 to 1984. Since 1988, the county has become one of the most Democratic in Colorado and the nation, largely due to the presence of the Telluride Ski Resort and the influx of liberal-minded voters in the 1960s and 1970s. These trends have made San Miguel similar in vein to other heavily Democratic ski resort counties like Blaine County in Idaho, Teton County in Wyoming, and Pitkin County within Colorado. In the 2000 presidential election, San Miguel County was Green Party candidate Ralph Nader's best countywide performance in the country with 17.2% of the vote.
San Miguel County is situated in Colorado House of Representatives, House District 58. The Current Representative is Marc Catlin, who has represented the county since 2017.[7]
