Dallas Divide

Dallas Divide (el. 8983 ft) is a high mountain pass in the United States state of Colorado located on State Highway 62 about 12 mi west of the town of Ridgway.

The pass is a saddle between the San Juan Mountains to the south and the Uncompahgre Plateau to the north and divides the Uncompahgre River watershed from the San Miguel River watershed and Ouray County from San Miguel County. The pass takes its name from Dallas Creek which drains the basin on the north side of Mount Sneffels into the Uncompahgre River. The divide's namesake is George M. Dallas, 11th Vice President of the United States.

A toll road was first constructed over Dallas Divide in 1880 linking the town of Dallas near Ridgway with Telluride. In 1890 the Rio Grande Southern Railroad was built over the divide from Ridgway to Telluride.
