High Point: Miller Peak, 9,466 feet

Elevation Change from Base: 4,466 feet

Vegetation at Highest Elevations: Douglas-fir–mixed conifer forests

The Huachuca Mountains are the third highest of the Sky Island mountain ranges in southeastern Arizona and they rise almost 4,500 feet above the desert floor. The mountain range is oriented in a northwestern direction giving it more north-facing slopes and perhaps a somewhat cooler climate than some of the other Sky Island mountain ranges with similar elevation. The highest elevations support mixed conifer forests on north-facing slopes and pine forests on south-facing slopes. Lower elevations have extensive oak and oak-pine woodlands. Management of this mountain range is divided mostly between the U.S Forest Service and Department of Defense (Fort Huachuca). Fort Huachuca occupies roughly the northeastern quarter of the range; the Forest Service manages the northwestern quarter and southern half. A small part of the southern end of the range is managed by the National Park Service as Coronado National Memorial.

Special Places:

  • East Side Canyons: Spring-fed streams, northeast orientation, and high canyon walls provide the canyons on the east side of the Huachuca Mountains with a moist cool environment unusual in the desert southwest. Water-loving trees like sycamores and maples grow along the streams often within a few feet of cacti, yucca, and agaves. The principal canyons accessible to visitors are Huachuca Canyon and Garden Canyon on Fort Huachuca; Ramsey Canyon, which is a private preserve managed by The Nature Conservancy; and Carr Canyon on the Coronado National Forest.
  • Miller Peak Wilderness: This wilderness of 20,190 acres occupies much of the high country at the southern end of the mountain range. It has an extensive trail system.
  • Coronado National Memorial: Francisco Vásquez de Coronado led the first major European expedition into the American Southwest in 1540 in search of the mythical Seven Cities of Cíbola. This park on the Mexican border was established to honor that quest. The park occupies the lower elevations at the southern end of the mountain range. It has excellent grasslands and evergreen oak woodlands.
