History
Formed in 1881 from Ouray County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Dolores County was created from Ouray County on February 19, 1881, and was named after the Dolores River. In 1923, Dolores exchanged land with San Miguel County to correct a boundary mistake. In 1970, Dolores gained territory from Montezuma County by agreement of both counties' boards of commissioners.
