The Sangre de Cristo Mountains are the southernmost subrange of the Rocky Mountains. They are located in southern Colorado and northern New Mexico in the United States. The mountains run from Poncha Pass in South-Central Colorado, trending southeast and south, ending at Glorieta Pass, southeast of Santa Fe, New Mexico. The mountains contain a number of fourteen thousand foot peaks in the Colorado portion, as well as all the peaks in New Mexico which are over thirteen thousand feet.
The Never Summer Mountains are a mountain range in the Rocky Mountains in north central Colorado in the United States consisting of seventeen named peaks. The range is located along the northwest border of Rocky Mountain National Park, forming the continental divide between the headwaters of the Colorado River in Rocky Mountain National Park to the local-east and the upper basin of the North Platte River to the local-west; the continental divide makes a loop in these mountains. The range is small and tall, covering only 25 sq mi (65 km2) with a north-south length of 10 mi (16 km) while rising to over 12,000 ft (3,700 m) at over ten distinct peaks. The range straddles the Jackson-Grand county line for most of its length, and stretches into Jackson and Larimer county at its northern end. A panoramic view of the range is available from sections of Trail Ridge Road in Rocky Mountain National Park. One of the northernmost peaks, Nokhu Crags, is prominently visible from the west side of Cameron Pass.
De Beque Canyon is a narrow canyon on the Colorado River in western Colorado in the United States. It is approximately 15 miles (24 km) long, located on the river downstream from the town of De Beque, in eastern Mesa County. The canyon forms a narrow passage where the river passes along the western end of the Grand Mesa. At its lower end, the canyon opens out on the eastern end of the Grand Valley at the town of Palisade, approximately 10 miles (16 km) east of Grand Junction. Interstate 70 follows the river through the canyon.

It is located in Taos County, New Mexico, about 8 miles (13 km) northeast of the town of Questa. Its summit is the highest point in the Latir Peak Wilderness, part of Carson National Forest. The peak's name means "deer" in Spanish.
The Mazatzal Mountains are a mountain range in south central Arizona, about 30–45 miles northeast of Phoenix and the Phoenix metropolitan area. The origin of the name remains obscure but one possibility is that it is from the Aztec language meaning "place of the deer". The crest of the Mazatzals forms the county line between Maricopa County and Gila County. SR 87, the Beeline Highway, traverses the Mazatzals on its way to Payson. The highest peak is Mazatzal Peak at 7,903 feet (2,409 m). They also include the Four Peaks, with elevation 7,659 ft, 2,334 m; a prominent mountain and landmark of the eastern Phoenix area.
The South Warner Wilderness is a federally designated wilderness area 12 miles (19 km) east of Alturas, California, USA. It encompasses more than 70,000 acres (283 km2) of the Warner Mountains. It is within the Modoc National Forest and managed by the US Forest Service. Elevations range from 5,000 feet (1,500 m) to 9,895 feet at Eagle Peak.
The Dinkey Lakes Wilderness is a federally designated wilderness area located 45 miles (72 km) northeast of Fresno, in the state of California, USA. It comprises 30,000 acres (12,141 ha) within the Sierra National Forest and was added to the National Wilderness Preservation System by the California Wilderness Act of 1984.
The Sylvania Mountains Wilderness is a federally designated wilderness area located 30 miles (48 km) east of Bishop in the state of California. The wilderness is 18,677acres in size and is managed by the Bureau of Land Management (BLM). The California Desert Protection Act of 1994 created the Sylvania Mountains Wilderness and was added to the National Wilderness Preservation System. The wilderness is bordered by Nevada stateline on the east, Piper Mountain Wilderness on the west and Death Valley National Park to the south.
Mount Alice is a high mountain summit in the northern Front Range of the Rocky Mountains of North America. The 13,315-foot (4,058 m) thirteener is located in the Rocky Mountain National Park Wilderness, 12.0 miles (19.3 km) southwest by south of the Town of Estes Park, Colorado, United States, immediately east of the Continental Divide between Boulder and Grand counties. Just who the namesake Alice was is unclear, but according to one source she was likely a "woman of ill repute".
The Middle Permian Toroweap Formation is a thin, darker geologic unit, between the brighter colored units of the Kaibab Limestone above, and Coconino Sandstone below. It is a prominent unit in Grand Canyon, Arizona, USA, found through sections of the South Rim, Grand Canyon, and the North Rim, of the Kaibab Plateau; also the Kaibab's southeast extension to Cape Royal, the Walhalla Plateau. The Colorado River of the Grand Canyon makes its excursion from due-south to due-west around the Walhalla Plateau, as it enters the east end of the Grand Canyon's interior, Granite Gorge. The formation is also found in southeast Utah.
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 expression 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.
Located directly downstream of the Little Colorado River confluence with the Colorado River, the Tanner Graben, in the Grand Canyon, Arizona, USA is a prominence and cliffside rock formation below the East Rim. Tanner Graben is located riverside, on the Colorado River, on a north-northwest bank at Mile 68.5, and lies opposite Tanner Canyon. The Tanner Rapid, created by Tanner Creek lies at the riverside foot of the graben. The graben is a pronounced feature because of the black Cardenas Basalt that forms the middle section of the graben, presumably free of debris accumulation by its cliff face steepness, and winds, and airflow drainage that course through the Colorado River's canyons; unprotected side canyons of Cardenas Basalt show accumulations as a slope-forming geologic unit, with little showing of black basalt.
The Thunder Lake Trail-Bluebird Lake Trail near Allens Park, Colorado was built in 1926. It was designed by National Park Service architects and was built by the Civilian Conservation Corps. It includes Late 19th and Early 20th Century American Movements, Rustic, and other architecture. The trail subsumes or is associated with Ouzel Lake Trail, the Arbuckle Lake(s) Trail, the Wild Basin Trail, and the North St. Vrain Creek Trail.
Bierstadt Lake is located in Larimer County, Colorado and within the Rocky Mountain National Park. Near McHenrys Peak and Longs Peak, there are "spectacular views" of the Continental Divide at the lake. The Bierstadt Lake Trailhead is located about 6.5 miles (10.5 km) from the turn-off at U.S. Route 36 into the Rocky Mountain National Park. During the summer, shuttle buses provide transportation to the trailhead.
The geology of Colorado was assembled from island arcs accreted onto the edge of the ancient Wyoming Craton. The Sonoma orogeny uplifted the ancestral Rocky Mountains in parallel with the diversification of multicellular life. Shallow seas covered the regions, followed by the uplift current Rocky Mountains and intense volcanic activity. Colorado has thick sedimentary sequences with oil, gas and coal deposits, as well as base metals and other minerals.
