Ouray County // is one of the 64 counties of the U.S. state of Colorado. As of the 2010 census, the population was 4,436.  The county seat is Ouray.  Because of its rugged mountain topography, Ouray County is also known as the Switzerland of America.
Ouray County was formed out of San Juan County on 18 January 1877, the first county designated by the newly formed Colorado State Legislature. It was named for Chief Ouray, a distinguished Ute Indian chief. Ouray was designated county seat on 8 March 1877. On 19 February 1881, Dolores County was formed out of Ouray County.
On 27 February 1883, Ouray County was split into San Miguel County and what is currently Ouray County. The portion that became San Miguel County almost retained the name Ouray County when the Colorado General Assembly initially renamed Ouray County as Uncompaghre County.  Four days later on 2 March 1883, the General Assembly changed its mind and changed the name of Uncompaghre County back to Ouray 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.  The new association consolidated the power of thirty-six mining properties in San Miguel, Ouray, and San Juan counties.  The SJDMA refused to consider any reduction in hours or increase in wages, helping to provoke a bitter strike.
According to the U.S. Census Bureau, the county has a total area of 542 square miles (1,400 km2), of which 542 square miles (1,400 km2) is land and 0.6 square miles (1.6 km2) (0.1%) is water.  The highest mountain in Ouray County is Mount Sneffels at 14,150 feet above sea level. Many high peaks of more than 13,300 feet also exist. Other prominent features in Ouray County include Log Hill Mesa and Pleasant Valley.

Ouray County, named Switzerland of America, is home to many parks and hiking trails. The Ridgway State Park is located due north of Ridgway on the Ridgway Reservoir and includes a marina and camping facilities as well as an extensive trail system. Within and surrounding the county are the Uncompahgre National Forest, Mount Sneffels Wilderness, and the Uncompahgre Wilderness. Leading through the county is the Bear Creek National Recreation Trail. Well known for its view of the San Juan and Cimmaron mountains, scenic highways such as the Alpine Loop National Scenic Back Country Byway and San Juan Skyway National Scenic Byway exist. The Great Parks Bicycle Route and Western Express Bicycle Route also go through Ouray County.
The Elks Lodge of Ouray County is only one of a very few surviving American locations for a bowling alley facility - a more famous one being Milwaukee, Wisconsin's Holler House - that uses exclusively human-operated pinsetting units to set the tenpins for bowling on its pair of vintage wood bowling lanes. 
Ouray County has two home rule municipalities, three census-designated places, and four unincorporated communities. The home rule municipalities are the city of Ouray and town of Ridgway, also the most populous settlements in the county. Loghill Village is the next largest development and is a residential, relatively affluent, community in comparison to the rest of the county. Along with Loghill, Portland and Colona serve as census-designated places within Ouray County. The unincorporated communities within the county are Camp Bird, Dallas, Thistledown, and Eldredge. All the communities, with the exception of Ridgway and Ouray, serve as primarily residential communities, though Loghill Village maintains a small tourism sector.
Colona, Eldredge, and Dallas are located in the northern reaches of the county along U.S. Highway 550, though Eldredge and Dallas are located within the valleys of the San Juan Mountains while Colona is in the short stretch of the Uncompahgre Valley within Ouray County. Portland is placed down valley of Ouray, though still south of Ridgway. Camp Bird and Thistledown are communities placed southwest of Ouray on Camp Bird Road. From north to south the communities are Colona, Eldredge, Dallas, Ridgway, Ouray, and then southwest along Camp Bird Road to Thistledown and Camp Bird. The historic towns of Sneffels and Ironton are located further west from Camp Bird and south of Ouray, respectively. Populations listed below are from the 2010 United States census data.
