A canyon or gorge is a deep cleft between escarpments or cliffs resulting from weathering and the erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering.
Moab is the largest city of, and the county seat on the southern edge of, Grand County in eastern Utah in the western United States, known for its dramatic scenery. The population was 5,046 at the 2010 census, and in 2018 the population was estimated to be 5,322. Moab attracts many tourists annually, mostly visitors to the nearby Arches and Canyonlands national parks. The town is a popular base for mountain bikers who ride the extensive network of trails including the Slickrock Trail, and for off-roaders who come for the annual Moab Jeep Safari.
The Grand Staircase–Escalante National Monument (GSENM) is a United States national monument originally designated in 1996 as 1,880,461 acres (7,610 km2) of protected land in southern Utah. In 2017, the monument's size was reduced by half in a succeeding presidential proclamation. The land is among the most remote in the country; it was the last to be mapped in the contiguous United States.
Canyoning is travelling in canyons using a variety of techniques that may include other outdoor activities such as walking, scrambling, climbing, jumping, abseiling (rappelling), and swimming.
Canyonlands National Park is an American national park located in southeastern Utah near the town of Moab.

The San Rafael Swell is a large geologic feature located in south-central Utah, USA about 16 miles (26 km) west of Green River. The San Rafael Swell, measuring approximately 75 by 40 miles, consists of a giant dome-shaped anticline of sandstone, shale, and limestone that was pushed up during the Paleocene Laramide Orogeny 60–40 million years ago. Since that time, infrequent but powerful flash floods have eroded the sedimentary rocks into numerous valleys, canyons, gorges, mesas, buttes, and badlands.
Between a Rock and a Hard Place is a 2004 autobiographical book by American mountain climber Aron Ralston. It details an incident that occurred in 2003 when Ralston was canyoneering in Bluejohn Canyon in the Utah desert, where he became trapped for five days.

Horseshoe Canyon, formerly known as Barrier Canyon, is in a remote area west of the Green River and north of the Canyonlands National Park Maze District in Utah, United States. It is known for its collection of Barrier Canyon Style (BCS) rock art, including both pictographs and petroglyphs, which was first recognized as a unique style here. A portion of Horseshoe Canyon containing The Great Gallery is part of a detached unit of Canyonlands National Park. The Horseshoe Canyon Unit was added to the park in 1971 in an attempt to preserve and protect the rock art found along much of its length.

Westbound traffic is charged a state park entrance fee at the park boundary.
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 Owyhee River Wilderness is located on the high basalt plateaus of Owyhee County in southwestern Idaho in the western United States. The wilderness area is named after and protects the upper Owyhee River, its tributaries, and the surrounding desert canyon landscape. Whitewater rafting is a popular recreational activity in this wilderness area. Managed by the Bureau of Land Management, it is the second-largest U.S. Wilderness Area that is not located within a National Forest, National Park, or National Wildlife Refuge. The BLM's Black Rock Desert Wilderness, located within Black Rock Desert – High Rock Canyon Emigrant Trails National Conservation Area, is larger. About 67.3 miles (108.3 km) of the Owyhee River is classified as a wild river.

Ekker Butte is a 6,260-foot (1,910-meter) elevation summit located in the northern reach of Glen Canyon National Recreation Area, in Wayne County of Utah, United States. It is situated seven miles southeast of Buttes of the Cross, six miles northeast of Elaterite Butte, and less than two miles outside the boundary of Canyonlands National Park, where it towers over 1,400 feet above the surrounding terrain. Distant views of this remote butte can be seen from the Grand View Point and Green River Overlooks at Island in the Sky of Canyonlands National Park. This geological landmark is named for the pioneering Art Ekker family which operated the nearby Robbers Roost Ranch and grazed cattle on land adjacent to the nearby Maze. Arthur Benjamin Ekker (1911–1978) took Robert Redford on a tour of nearby Robbers Roost, the hideout of outlaw Butch Cassidy and the Wild Bunch.
