Montezuma County lies in the southwestern corner of Colorado, a large county with 25,849 inhabitants in 2020. It was created by the Colorado Legislature in 1889 and named for Moctezuma II, a revered Mexican chief of the Aztec Indians.
The county seat is Cortez, and the county is rich with Native American archeological sites and structures. Mesa Verde National Park and Canyons of the Ancients National Monument house the cliff dwellings and other historical artifacts.

Approximately one-third of Montezuma County is tribal land, one-third is federally managed, and the remaining third is privately owned or belongs to the state or county. The elevations range from 6,000 to 14,000 feet, and Colorado’s second-largest reservoir, McPhee Reservoir, is found here.
