How Dolores came to be

From Wikipedia’s history of Dolores.

Read it all →

The Dolores, Colorado, post office opened on April 5, 1878, and the Town of Dolores was incorporated on July 19, 1900. Dolores (Spanish for "sorrows" and named for the river on which it is located) is located at the mouth of the Dolores Valley and the upper reaches of McPhee Reservoir, approximately 40 miles (64 km) from the Four Corners Monument. Established as a station on the Rio Grande Southern Railroad, it replaced the earlier town, Big Bend, now covered by McPhee Reservoir. McPhee Reservoir is named for a company town founded by New Mexico Lumber Company, that is now covered by the reservoir.
