The Chuska Mountains span 60 mi (97 km) in northwestern New Mexico and northeastern Arizona in the United States and are encompassed by the Navajo Nation. There are 151 peaks. Roof Butte is the highest at 9,780 ft (2,981 m) and the most prominent (3,127 ft/953 m).

The Chuska Mountains are the eroded surfaces of old explosive volcanoes. The rock types in this volcanic field are unusual in chemistry. The Navajo volcanic field is a diffuse group of intrusions, dikes, and some extrusive rocks of early Neogene (mid-Cenozoic) age scattered between Gallup and Farmington, New Mexico and Window Rock, Arizona.

The Chuska Mountains are located in the heart of the Navajo Nation and lays on the Arizona and New Mexico border. With an elevation region ranging from 6,000 to 9,500 feet, a day hike in the Chuska Mountains Trail can be a glorious hike to an amazing land that is experienced by the few.

The Chuska Mountains are eroded in Chuska Sandstone and volcanic rocks of Tertiary age. Prominent cliffs which are below and bound most of the upland surface are broken by canyons that cut into the uplands. The Lukachukai Mountains are a northwesterly-extend-ing spur of the Chuska Mountains, separated from the

The Chuska Mountains rise to more than 9,000 feet (2,700 metres) in the southwest. The San Juan River, at Lake Navajo, forms the county’s northeastern boundary, then receives the Las Animas River and flows in a long curve through the county.

Rising along the border of New Mexico and Arizona within the Navajo Nation, the Chuskas were “the backbone of Diné transhumance,” according to historian Dr. Marsha Weisiger, where many families “mapped a pattern that they would trace again and again for generations.”
