Arizona’s highest point is Humphreys Peak, a 3852-meter-high (12,637-foothigh) mountain in the Kachina Peaks Wilderness 18 kilometers (11 miles) north of Flagstaff. It is the highest of the San Francisco Peaks, remnants of an extinct stratovolcano. The state’s lowest point is along the Colorado River near San Luis, which lies at only 22 meters (72 feet) above sea level.

Colorado

Mount Elbert, rising 4401 meters (14,440 feet) above sea level, is Colorado’s highest point as well as the highest summit in the North American Rockies. The mountain, located 19 kilometers (12 miles) southwest of Leadville, is also the second-highest summit in the continental United States. The lowest point in Colorado is found on the Arikaree River where it flows into Kansas, at an elevation of 1011 meters (3317 feet). This spot is also the highest low point of any US state.

New Mexico

The Sangre de Cristo Mountains are home to Wheeler Peak, New Mexico's highest mountain. At 4011 meters (13,161 feet), the mountain is a popular hiking and climbing destination. It was named in honor of George Montague Wheeler, an American pioneering explorer and naturalist. New Mexico’s lowest point is the Red Bluff Reservoir on the Pecos River, with an elevation of 866 meters (2842 feet).

Utah

At 4125 meters (13,534 feet), Kings Peak is Utah's highest point, located in the Uinta Mountains of north-central Duchesne County. The peak is regarded as the hardest state high point to climb without special rock climbing skills or a guide; the easiest trail to the summit requires a 47-kilometer (29-mile) round-trip hike. Beaver Dam Wash, at the Utah-Arizona state line in Washington County, is the lowest point in the state at 664 meters (2178 feet) above sea level.
