History
It is thought that the area has been the site of human habitation since at least 2500 B.C. Dolores County's western portions were densely populated between 900 and 1300 AD. Population estimates of as many as 10,000 inhabitants, with villages containing hundreds of rooms, have been discovered by archaeologists and other researchers. But this population was destroyed or migrated elsewhere, apparently following a drought and severe societal upheaval in the 14th century, and for centuries thereafter, both the western and eastern mountainous areas of the county were occupied mostly by nomads, including the

Anglo trappers worked the mountains of eastern Dolores County as early as 1832–33, and gold was discovered in the County in 1866. But it was not until the area was taken from the Ute and removed from the Ute Reservation by the

Telluride, and Ridgway in 1890-92 The RGS served the eastern end of Dolores County until 1952 when it was abandoned. (The western portion of the county has never had railroad service.)
Rico's high point was in 1892, when the mining district population was more than 5,000; three times the current population of the entire county. The
1893 Silver Panic hit the town hard; by 1900 the population was 811. The mountainous area of Dolores County went through a series of booms and busts through the 20th Century. The low point of the community came in 1974 with an estimated population of 45; since then the town has become a bedroom community for Telluride and has limited tourism and subdivisions; the population has rebounded to almost 300. Efforts are underway in the early 21st Century to again begin major mining activities in the region.
Dove Creek was a way station on the Old Spanish Trail from the mid 19th century, for caravans and travelers moving between Santa Fe, Salt Lake City, and northern California and Nevada. The western portion of the county was used, beginning in the 1870s, for cattle ranching, but the lush grass soon suffered from

, pinyon, and juniper. Homesteading in the area became common beginning in 1914, and dryland farming expanded throughout the Great Sage Plain. Today dryland farming of pinto beans and winter wheat is still a mainstay of the county's economy. But the development of irrigation using water from the
Dolores Project in the 1980s, with the construction of McPhee Reservoir (immediately upstream in Montezuma County), has changed the history and population of the county.
Dolores County was created by the Colorado legislature on February 19, 1881, from the western portions of
Ouray County, and was named for the
Dolores River, which heads up in the county and passes through the county in the Dolores Canyon. The complete Spanish name was ''Rio de Nuestra Señora de los Dolores (River of our Lady of Sorrows), ''as reported by Father
Silvestre Vélez de Escalante in 1776. Originally set in
