It lies between Roosevelt Lake to the south, the Tonto Basin to the west, Cherry Creek to the east, and Pleasant Valley to the north. The range is one of several, including the Bradshaw Mountains, Mingus Mountain of the Black Hills, and the Mazatzal Mountains, which form a transitional zone between the lowland deserts of southern Arizona and the Colorado Plateau of northeastern Arizona. The highest point in the range is Aztec Peak, at an elevation of 2345 m (7694 ft).

The Rawhide Mountains are a mountain range of western Arizona, in the southwest of Mohave County. It is part of a block of mountain ranges on the north of an insular region called the Maria fold and thrust belt, containing mountain ranges, valleys, and plains. The Rawhide Mountains border the much smaller Artillery Mountains southeast, bordering on Alamo Lake State Park and the south-flowing Big Sandy River.
The Aubrey Peak Wilderness is a 15,400-acre (6,230 ha) wilderness administered by the Bureau of Land Management (BLM). The wilderness is located in northwest Arizona in the southwest of Mohave County, a region of the southeastern Mojave Desert's extension into northwest Arizona.
Aubrey Peak, also known as Grooms Peak, is a summit located 35 miles east-northeast of Lake Havasu City in Mohave County, Arizona and is in the Hualapai Mountains.
Sugarloaf Mountain, of Arizona is the tallest peak in the arid, low elevation Hummingbird Springs Wilderness of northwest Maricopa County, and about 65 miles (105 km) west of Phoenix. It rises in the Tonopah Desert about 10 miles (16 km) northwest of the Belmont Mountains. Hummingbird Springs Wilderness is just north of the Big Horn Mountains Wilderness. The two are separated only by a jeep trail that leads to Hummingbird Springs.
Dutch Flat of Arizona is a valley south of the Sacramento Valley and Interstate 40 in southern Mohave County.
The Black Hills of Greenlee County are a 20 mi (32 km) long mountain range of the extreme northeast Sonoran Desert bordering the south of the White Mountains of eastern Arizona's transition zone.
The Chino Valley of Arizona is a large, 70-mi (113 km) long valley, centered on Seligman, Arizona in northwest Yavapai County and southwest Coconino County. The valley is located at the southwest of the Coconino Plateau and lies in the extreme northwest of Arizona's transition zone.
The Santa Maria Mountains are a 16-mi (26 km) long mountain range in central-northwest Arizona, and in northwest Yavapai County. The range lies in a region of mesas and mountain ranges in the northwest of Arizona's transition zone. The Santa Maria Mountains lie east of the transition zone's northwest perimeter, the parallel Aquarius and Mohon Mountains.
The Aquarius Mountains are a 45-mi (72 km) long mountain range in southeast Mohave County, Arizona. The range lies in the northwest of the Arizona transition zone, and at the southwest of the Coconino Plateau, a subsection of the Colorado Plateau.
The Sierra Prieta is a 14 miles (23 km) long mountain range in central-northwest Arizona. The range is the mountainous region west of Prescott, with prominent Thumb Butte, 6,514 feet (1,985 m), a volcanic plug, on the city's west perimeter.
Aubrey Valley is a 35-mile (56 km) long valley located in southwest Coconino County, Arizona with the northwest border of Yavapai County. The valley is located at the southwest border of the Aubrey Cliffs; to the west and southwest, the Yampai Divide and the Seventyfour Plains form flatlands between four bordering mountain ranges at the northwest terminus of the Arizona transition zone.
The Toroweap Fault of northwest Arizona and southwest Utah is part of a fault system of the west Grand Canyon region, Arizona, USA; also the west perimeter regions of the Coconino and Colorado Plateaus. The Hurricane Fault originates at the Toroweap Fault, in the region of the Colorado River, and strikes as the westerly depression of the Toroweap Fault. The Toroweap strikes northerly from the Colorado at the east of Toroweap Valley, and enters south Utah; from the Colorado River, the Hurricane Fault strikes north-northwest along the west flank of the small, regional Uinkaret Mountains, the west border of Toroweap Valley. The Hurricane Fault, and the Hurricane Cliffs strike into southwest Utah as part of the west, and southwest perimeter of the Colorado Plateau. The Hurricane Cliffs are made of Kaibab Limestone, an erosion resistant, cliff-forming rock unit.
The Lower Permian Esplanade Sandstone is a cliff-forming, resistant sandstone, dark red, geologic unit found in the Grand Canyon. The rock unit forms a resistant shelf in the west Grand Canyon, south side of the Colorado River, at the east of the Toroweap Fault, down-dropped to west, southeast of Toroweap Overlook, and west of Havasupai. The red, sandstone shelf, The Esplanade is about 20-mi long. At Toroweap Overlook region, Toroweap Valley with Vulcan's Throne, Uinkaret volcanic field, the resistant Esplanade Sandstone is described in access routes exploring the Toroweap Lake area.
The Pennsylvanian to Lower Permian,, Supai Group, is a slope-forming section of red bed deposits found at the southwest-to-south Colorado Plateau. Cliff-forming interbeds (sandstone) are noticeable throughout the group, as well as the largest cliff-former the topmost member Esplanade Sandstone. The Supai Group is especially exposed throughout the Grand Canyon in northwest Arizona, as well as local regions of southwest Utah. It outcrops southeastwards in Arizona at Chino Point, Sycamore Canyon, and famously at Sedona as parts of Oak Creek Canyon. In the Sedona region, it is overlain by the Hermit Formation, and the colorful Schnebly Hill Formation.
The Mesoproterozoic Dripping Spring Quartzite is a resistant, purple quartzite formation found in central and southeast Arizona, USA. It is a cliff-forming purplish unit found in the lower sections of the Apache Group, units of originally sedimentary layers, but later metamorphosed. The Apache Group is coeval with a similar aged Proterozoic sequence of eight geologic units found in the lowest geologic sequences of the Grand Canyon, the Grand Canyon Supergroup.
The Grand Wash Cliffs extend south-southeast from the Grand Canyon-Parashant National Monument in northwest Arizona west of the Shivwits Plateau south through the Grand Cliffs Wilderness and into the Lake Mead Recreation Area. The Grand Wash Cliffs cross the Grand Canyon where the Colorado River enters Lake Mead. To the south of the Grand Canyon the Grand Wash Cliffs continue past the east side of Grapevine Mesa and then southeast above and east of the Hualapai Valley forming the southwest margin of the Music Mountains.
The Apache Group is a Mesoproterozoic group of geologic formations in the southwestern United States.
