Natural Bridges National Monument is a U.S. National Monument located about 50 miles (80 km) northwest of the Four Corners boundary of southeast Utah, in the western United States, at the junction of White Canyon and Armstrong Canyon, part of the Colorado River drainage. It features the thirteenth largest natural bridge in the world, carved from the white Permian sandstone of the Cedar Mesa Formation that gives White Canyon its name.
Canyonlands National Park is an American national park located in southeastern Utah near the town of Moab. The park preserves a colorful landscape eroded into countless canyons, mesas, and buttes by the Colorado River, the Green River, and their respective tributaries. Legislation creating the park was signed into law by President Lyndon Johnson on September 12, 1964.
Lake Powell is a reservoir on the Colorado River, straddling the border between Utah and Arizona, United States. Most of Lake Powell, along with Rainbow Bridge National Monument, is located in Utah. It is a major vacation spot that around two million people visit every year. It is the second largest man-made reservoir by maximum water capacity in the United States behind Lake Mead, storing 24,322,000 acre feet (3.0001×1010 m3) of water when full. However, due to high water withdrawals for human and agricultural consumption, and because of subsequent droughts in the area, Lake Mead has fallen below Lake Powell in size several times during the 21st century in terms of volume of water, depth and surface area.
The Colorado Plateau, also known as the Colorado Plateau Province, is a physiographic and desert region of the Intermontane Plateaus, roughly centered on the Four Corners region of the southwestern United States. This province covers an area of 336, 700 km2 (130,000 mi2) within western Colorado, northwestern New Mexico, southern and eastern Utah, and northern Arizona. About 90% of the area is drained by the Colorado River and its main tributaries: the Green, San Juan, and Little Colorado. Most of the remainder of the plateau is drained by the Rio Grande and its tributaries.
Wrather Arch is a cave type natural arch in the Paria Canyon-Vermilion Cliffs Wilderness, in Coconino County, northern Arizona.
Glenwood Canyon is a rugged scenic 12.5 mi (20 km) canyon on the Colorado River in western Colorado in the United States. Its walls climb as high as 1,300 feet (400 m) above the Colorado River. It is the largest such canyon on the Upper Colorado. The canyon, which has historically provided the routes of railroads and highways through western Colorado, currently furnishes the routes of Interstate 70 and the Central Corridor between Denver and Grand Junction. The canyon stretches from near Dotsero, where the Colorado receives the Eagle River, downstream in a west-southwest direction to just east of Glenwood Springs, on the mouth of the Roaring Fork. Most of the canyon is in Garfield County, with the upper portion near Dotsero lying in Eagle County.
The Dolores River Canyon is located in southwestern Colorado, USA, west of the town of Naturita and north of the town of Dove Creek.
Rattlesnake Canyon is a scenic area within the Black Ridge Canyons Wilderness which in turn forms the core of the Bureau of Land Management administered McInnis Canyons National Conservation Area in west central Colorado. The canyon contains nine natural arches, the second highest concentration of such arches in the United States, after the much better known Arches National Park.
Ruby Canyon is a roughly 25 mile (40 km) long canyon on the Colorado River located on the Colorado-Utah border in the western United States, and is a popular destination for rafting. The canyon takes its name from the red sandstone cliffs which line the canyon walls.
Westwater Canyon is a canyon located on the Colorado River in Eastern Utah between the Utah/Colorado state line and Cisco, Utah. The inner gorge of the canyon is made up of black Precambrian rock and contains class III and IV rapids which are sought after by whitewater enthusiasts. The most notable rapid, called "Skull", is the most significant.
The Sierra Ancha is a mountain range in Gila County, in central Arizona. 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).
Navajo Sandstone is a geological formation in the Glen Canyon Group that is spread across the U.S. states of southern Nevada, northern Arizona, northwest Colorado, and Utah as part of the Colorado Plateau province of the United States.
Dark Canyon Wilderness is a designated Wilderness Area in the heart of southeast Utah's canyon country, part of the Bears Ears National Monument. The wilderness is named for its high steep walls that narrow in the lower section so that they block the light in the morning and late afternoon. The roughly horseshoe-shaped wilderness is made up of the upper part of 40-mile-long (64 km) Dark Canyon and two major tributaries, Woodenshoe Canyon and Peavine Canyon in the Manti-La Sal National Forest. These canyons all descend from pine-covered Elk Ridge northeast of Natural Bridges National Monument. Dark Canyon continues west within a U.S. Bureau of Land Management primitive area that is recommended for wilderness designation. The last four miles (6.4 km) of the main canyon drop steeply through Glen Canyon National Recreation Area into Lake Powell.
The Canyons of the Escalante is a collective name for the erosional landforms created by the Escalante River and its tributaries—the Escalante River Basin. Located in southern Utah in the western United States, these sandstone features include high vertical canyon walls, numerous slot canyons, waterpockets, domes, hoodoos, natural arches and bridges. This area—extending over 1,500 square miles (3,885 km2) and rising in elevation from 3,600 ft (1,097 m) to over 11,000 ft (3,353 m)—is one of the three main sections of the Grand Staircase-Escalante National Monument, and also a part of the Glen Canyon National Recreation Area, with Capitol Reef National Park being adjacent to the east.
Coyote Gulch is a tributary of the Escalante River, located in Garfield and Kane Counties in southern Utah, in the western United States. Over 25 mi (40 km) long, Coyote Gulch exhibits many of the geologic features found in the Canyons of the Escalante, including high vertical canyon walls, narrow slot canyons, domes, arches, and natural bridges. The upper sections of Coyote Gulch are located within the Grand Staircase-Escalante National Monument while its lower sections are located in the Glen Canyon National Recreation Area.
The Canyon Lands Section of the Colorado Plateau is a physiographic section of the larger Colorado Plateaus province, which in turn is part of the larger Intermontane Plateaus physiographic division in the Western United States
The Devils Garden of the Grand Staircase-Escalante National Monument (GSENM) in south central Utah, United States, is a protected area featuring hoodoos, natural arches and other sandstone formations. The United States Geological Survey (USGS) designated the name Devils Garden—without an apostrophe according to USGS naming conventions—on December 31, 1979. The area is also known as the Devils Garden Outstanding Natural Area within the National Landscape Conservation System.
Cebolla Wilderness is a 61,600-acre (24,900 ha) Wilderness area located within the El Malpais National Conservation Area in New Mexico. The area was added to the National Wilderness Preservation System on December 31, 1987 by Public Law 100-225. The area is a bordered by the Acoma Pueblo to the east and the El Malpais National Monument and New Mexico Highway 117 to the west. Elevations range from 7,000 feet (2,100 m) to 8,200 feet (2,500 m). The sandstone canyons and mesas of this rimrock area include features such as La Ventana natural arch.
