Located in the US state of Arizona, the White Mountains are a group of 227 summits that lie mostly within the boundaries of the Fort Apache Reservation. The highest and most prominent point in the range is Mount Baldy (11,421 ft/3,481 m).
The White Mountains are located in Arizona’s Transition Zone, a northwest-trending escarpment of mountainous terrain bounded by the Colorado Plateau to the north and the Great Basin to the south. As such, the White Mountains share many topographic and geologic characteristics with both regions.
Several prominent mountain ranges and peaks lie in the Transition Zone alongside the White Mountains, including the Mazatzal Mountains, Santa Maria Mountains, and Sierra Ancha. The Gila Mountains of Graham County and Black Hills of Greenlee County border the White Mountains to the south. To the east, the Sierra Aguilada Mountains extend for roughly 15 miles (24 km) through southwest New Mexico.
The White Mountains also serve as the western extension of the Mogollon Rim, a prominent escarpment of the Colorado Plateau that stretches 115 miles (185 km) from northern Yavapai County eastward before terminating near the New Mexico border.
Most of the White Mountains lie within the 1.6-million-acre (647,500 ha) Fort Apache Reservation. But parts of the range also extend into the Apache-Sitgreaves National Forests.
The jointly administered Apache-Sitgreaves National Forests covers roughly 2.76 million acres (1.1 million ha) of land along the Mogollon Rim. It extends into the White Mountains region in east-central Arizona, as well as a small part of extreme western New Mexico. The forest contains three designated wilderness areas: Mount Baldy Wilderness, Escudilla Wilderness, and Bear Wallow Wilderness.
To the south and southwest of the Apache-Sitgreaves National Forests, the Tonto National Forest abuts the Mogollon Rim and protects 2,873,200 acres (1,162,700 ha) of varied terrain.
Meanwhile, to the north of the White Mountains, Petrified Forest National Park protects 200,000 acres (81,000 ha) of the Colorado Plateau. This region of Arizona is largely characterized by deeply etched plateaus and tablelands that are dissected by the Colorado River and its tributaries.
However, the White Mountains in Arizona should not be confused with the White Mountains, a set of summits located east of the Sierra Nevada in California, or the White Mountains of New Hampshire.
The White Mountains lie within a narrow band that separates two contrasting geomorphic provinces, the Colorado Plateau and the Great Basin. This region, referred to as the Transition Zone, has experienced extensive volcanism and tectonic extension in the past, both of which have contributed to the complex topography and natural features observed in the area today.
The White Mountains region is widely believed to be the remnant of the middle Tertiary-aged Mount Baldy Volcano. As such, the range is characterized by irregular topography and it is home to cinder codes, lava-capped mesas, and deep canyons, all of which formed during the late Tertiary and Quaternary.
Volcanic activity dominated eastern Arizona and western New Mexico between the Eocene and Oligocene, about 34 to 24 million years ago. About 9 to 2 million years ago, molten rock and ash from eruptions in the White Mountains region filled deep valleys and constructed the Mount Baldy stratovolcano. Mudflows and sediment were subsequently transported and deposited over the surrounding landscape.
Today, most of the volcanic landforms of the White Mountains Volcanic eruptions have been weathered away by erosion or covered by more recent (3 million to 300,000-year-old) eruptions in the Springerville Volcanic Field. Mount Baldy, the tallest peak in the range, is the most prominent remnant of the region’s extensive volcanic past.
Though no glaciers remain on Mount Baldy today, geologists also theorize that at least four periods of glaciation occurred in the White Mountains during the late Quaternary period. Extensive glaciation cut broad valleys into the northwestern, northern, and eastern slopes of Mount Baldy.
The White Mountains lie in the Arizona/New Mexico Mountains ecoregion, which stretches across Arizona, central and northwestern New Mexico, and parts of southwestern Colorado. Topography in the region is mostly dominated by steep foothills and mountains with some deeply dissected high plateaus.
Due to the region’s varying elevation gradients and topography, the White Mountains sustain a wide variety of flora and fauna. The ecosystems in the foothills of the White Mountains are characterized by mixed grasses, chaparral brush, oak-juniper woodland, and pinyon-juniper woodland.
Forests of spruce and Douglas fir, like those found in the Southern Rockies and the Wasatch Range, are also found in the region. Other characteristic trees that you’ll see in the range include Chihuahua pine and Apache pine.
The most notable large mammals in the White Mountains include mule deer, coyote, mountain lion, black bear, and bobcat. Small mammals, including deer mouse, longtail weasel, porcupine, red squirrel, and Colorado chipmunk also thrive in the region.
The White Mountain Apache Tribe was also the first tribe in the area to officially facilitate the recovery of the Mexican gray wolf, which had been extirpated from the southwest US by the 1970s. Today, Tribal lands protect and preserve five federally listed species: Apache trout, Mexican spotted owl, Mexican wolf, bald eagle, and loach minnow.
The White Mountains are the native homeland of the White Mountain Apache Tribe, a traditionally nomadic people who were known to travel widely throughout east-central Arizona.
The easternmost band of the Western Apache, the White Mountain Apache are related to other Apache nations, including the Chiricahua, Mescalero, Jicarillo, Lipan, and Kiowa-Apache peoples. However, each Tribe has its own dialects as well as its own history and culture.
When the first Europeans arrived in the White Mountains in the mid 1800s, the White Mountain Apache people lived in family groups and bands along many of the region’s major waterways. By the late 1860s, the US Army had begun planning expeditions into White Mountain Apache territory to kill or capture Apache people.
However, when a group of US military men, led by Captain John Barry, arrived in what they referred to as “Miguel’s Village,” they were met with hospitality. White Mountain Apache leaders agreed to allow the US military to establish Camp Ord, which would later be renamed to Fort Apache, at the confluence of the East and North Forks of the White River.
By 1891, the Fort Apache Reservation was established. It originally included the San Carlos Apache Reservation but has since been separated into its own territory. Today, the Fort Apache Reservation consists of 1.67 million acres (675,800 ha) in east-central Arizona. About 16,000 Tribal members are registered with the White Mountain Apache Tribe.
Mount Baldy, the tallest peak in the White Mountains, lies along the eastern edge of the White Fort Apache Reservation. Mount Baldy is a sacred mountain to many local Tribes, and it is part of a designated Tribal Wilderness. Non-tribal members are not allowed to summit the peak without express permission of the Tribe.
There are many miles of scenic hiking trails in the White Mountains of Arizona. These are some of the top hiking areas to visit in the range.
The Apache-Sitgreaves National Forests covers 4,315 sq. miles (11,175 sq. km) of land, making it the second largest national forest in Arizona. Opportunities in the forest abound for hiking, mountain biking, horseback riding, and fishing. The forest is divided into five ranger districts—Black Mesa, Lakeside, Springerville, Alpine, and Clifton.
The Alpine District of the national forest lies in the White Mountains region and contains a wide range of recreation options, including the Bear Wallow Wilderness, Luna Lake Recreation Area, Williams Valley Recreation Area, Hannagan Meadows Recreation Area, and Escudilla Wilderness.
Many popular trails also traverse the area, including the trails to Aker Lake, Bear Wallow, Black River Mainstem, Blue Lookout, and George’s Lake.
In 1987, the White Mountains Trail System was established to preserve non-motorized trails for recreation in the White Mountains region. Today, the trail system consists of over 200 miles (322 km) of multi-use trails stretching from Pinetop-Lakeside to Show Low.
Trails in the system range anywhere from 8 to 16 miles (13 to 26 km) in length and can also be modified to accommodate various skill levels, abilities, and adventure styles. Popular trails include the Land of the Pioneers, Timber Mesa, Buena Vista, and Show Low Bluff.
