Angel Arch is the largest natural arch located within Canyonlands National Park, in San Juan County, Utah. [1] [2] Some consider it the most beautiful and spectacular arch in the park, if not the entire canyon country. [3] It is situated in a side canyon of Salt Creek Canyon, in the Needles District of the park. Precipitation runoff from Angel Arch drains north into the nearby Colorado River via Salt Creek. A 29-mile round-trip hike to Angel Arch leads to a viewpoint, and an additional 0.75-mile trail scrambles up into the arch opening. The arch's descriptive name comes from its resemblance to an angel with wings folded, and standing with its back to the arch opening. [4] Before this feature's name was officially adopted in 1963 by the U.S. Board on Geographic Names, it was called Pegasus Arch. [1] The first ascent was made in June 1993, by John Markel and Kevin Chase. [5]
This geological formation is an eroded fin composed of Cedar Mesa Sandstone, which is the remains of coastal sand dunes deposited about 245–286 million years ago, during the early Permian period. [6] The top of the formation rises 450 feet (140 m) above the canyon floor, and the opening has a height of 135 feet (41 m), and a width of 120 feet (37 m). [7]
Spring and fall are the most favorable seasons to visit Angel Arch. According to the Köppen climate classification system, it is located in a Cold semi-arid climate zone, which is defined by the coldest month having an average mean temperature below −0 °C (32 °F) and at least 50% of the total annual precipitation being received during the spring and summer. This desert climate receives less than 10 inches (250 millimeters) of annual rainfall, and snowfall is generally light during the winter.
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 numerous 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 B. Johnson on September 12, 1964.
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, northern Arizona, and a tiny fraction in the extreme southeast of Nevada. 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.
The exposed geology of the Canyonlands area is complex and diverse; 12 formations are exposed in Canyonlands National Park that range in age from Pennsylvanian to Cretaceous. The oldest and perhaps most interesting was created from evaporites deposited from evaporating seawater. Various fossil-rich limestones, sandstones, and shales were deposited by advancing and retreating warm shallow seas through much of the remaining Paleozoic.
The exposed geology of the Capitol Reef area presents a record of mostly Mesozoic-aged sedimentation in an area of North America in and around Capitol Reef National Park, on the Colorado Plateau in southeastern Utah.
The 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.
The Cutler Formation or Cutler Group is a rock unit that is exposed across the U.S. states of Arizona, northwest New Mexico, southeast Utah and southwest Colorado. It was laid down in the Early Permian during the Wolfcampian epoch.
The Moenkopi Formation is a geological formation that is spread across the U.S. states of New Mexico, northern Arizona, Nevada, southeastern California, eastern Utah and western Colorado. This unit is considered to be a group in Arizona. Part of the Colorado Plateau and Basin and Range, this red sandstone was laid down in the Lower Triassic and possibly part of the Middle Triassic, around 240 million years ago.
Cedar Mesa Sandstone is a sandstone member of the Cutler Formation, found in southeast Utah, southwest Colorado, northwest New Mexico, and northeast Arizona.
In geology, the Paradox Formation Is a Pennsylvanian age formation which consists of abundant evaporites with lesser interbedded shale, sandstone, and limestone. The evaporites are largely composed of gypsum, anhydrite, and halite. The formation is found mostly in the subsurface, but there are scattered exposures in anticlines in eastern Utah and western Colorado. These surface exposures occur in the Black Mesa, San Juan and Paradox Basins and the formation is found in the subsurface in southwestern Colorado, southeastern Utah, northeastern Arizona and northeastern New Mexico.
The White Rim Sandstone is a sandstone geologic formation located in southeastern Utah. It is the last member of the Permian Cutler Group, and overlies the major Organ Rock Formation and Cedar Mesa Sandstone; and again overlies thinner units of the Elephant Canyon and Halgaito Formations.
Druid Arch is an iconic 150-foot tall Cedar Mesa Sandstone arch located within the Needles District of Canyonlands National Park, in San Juan County, Utah. It is situated at the head of Elephant Canyon, and precipitation runoff from Druid Arch drains north into the nearby Colorado River via Elephant Canyon. Druid Arch is one of the most popular hiking destinations in the Needles district. A 5.4 mile hike to Druid Arch starts at the Elephant Hill Trailhead, and the final quarter-mile is steep with some scrambling and one ladder. The name comes from its resemblance to the Stonehenge monument in England, which is believed to be a Druid temple. This feature's name was officially adopted in 1963 by the U.S. Board on Geographic Names.
Monster Tower is a 600-foot (180-meter) tall sandstone tower located in the Island in the Sky District of Canyonlands National Park, in San Juan County, Utah, United States.
Washer Woman is a 500-foot (150-meter) tall sandstone arch and tower located in the Island in the Sky District of Canyonlands National Park, in San Juan County, Utah. It is situated 300 feet northwest of the slightly higher Monster Tower. Washer Woman is so named because the feature gives the appearance of a washerwoman bent over a washtub. This geographical feature's name was officially adopted in 1986 by the U.S. Board on Geographic Names after previously having similar names such as Washer-Woman Arch and The Washer Woman. Washer Woman and Monster Tower are an eroded fin composed of Wingate Sandstone, which is the remains of wind-borne sand dunes deposited approximately 200 million years ago in the Late Triassic. Airport Tower is set 1.6 mi (2.6 km) to the east, and Mesa Arch is situated 1.5 mi (2.4 km) to the west. A short hike to Mesa Arch provides the easiest view of Washer Woman. Access to this formation is via the four-wheel drive White Rim Road, which is the other option to see it. The top of this geological formation rises 1,300 feet above the road in approximately one mile. Precipitation runoff from Washer Woman drains southeast into the nearby Colorado River via Buck Canyon.
Airport Tower is a 700-foot (210-meter) tall sandstone butte located in the Island in the Sky District of Canyonlands National Park, in San Juan County, Utah. It is situated 1.64 mile east of Washer Woman, which is a towering arch similar in height. Each are composed of Wingate Sandstone, which is the remains of wind-borne sand dunes deposited approximately 200 million years ago in the Late Triassic. The nearest higher neighbor is Monster Tower, 1.6 mi (2.6 km) to the west, Tiki Tower is one-half mile northwest, and Mesa Arch is situated 3.2 mi (5.1 km) to the west. A short hike to Mesa Arch provides the easiest view of Airport Tower. Access to this tower is via the four-wheel drive White Rim Road, which is another option to see Airport Tower. The top of this geological formation rises 1,400 feet above the road in less than one mile. Precipitation runoff from Airport Tower drains southeast into the nearby Colorado River via Buck and Lathrop Canyons. This geographical feature's name was officially adopted in 1986 by the U.S. Board on Geographic Names. It was so named because the rock formation resembles the appearance of an airport control tower.
Zeus and Moses are a pair of 500-foot-tall (150 m) sandstone formations located in the Island in the Sky District of Canyonlands National Park, in San Juan County, Utah, United States. These rock towers' names refer to Zeus, a god in Greek mythology, and Moses, an important prophet in several religious traditions. Zeus and Moses are composed of Wingate Sandstone, which is the remains of wind-borne sand dunes deposited approximately 200 million years ago in the Late Triassic. This formation is situated in Taylor Canyon, 3 mi (4.8 km) north-northeast of Upheaval Dome. Access to the towers is via the four-wheel-drive White Rim Road, and a spur road into Taylor Canyon. The top of this geological formation rises 900 feet above the canyon floor at road's end, approximately one-half mile away. Precipitation runoff from Zeus and Moses drains into the nearby Green River via Taylor Canyon.
Aztec Butte is a sandstone summit, elevation 6,312 feet, located in the Island in the Sky District of Canyonlands National Park, in San Juan County, Utah. Aztec Butte is composed of white cross-bedded Navajo Sandstone, which is the remains of wind-borne sand dunes deposited approximately 170 million years ago during the Jurassic Period. It resembles the Pyramid of the Sun in Mexico, which was built by the Aztecs.
Buttes of the Cross is two sandstone summits located in the northern reach of Glen Canyon National Recreation Area, in Wayne County of Utah, United States. The larger and higher south butte reaches an elevation of 5,642 feet, whereas the north butte rises to 5,569 feet, with approximately 0.6 miles (0.97 km) separation between them. When viewed from the north-northeast near Labyrinth Canyon, they align to form the shape of a cross, creating the appearance of a single butte. The name "Butte of the Cross" was first applied by John Wesley Powell during the Powell Geographic Expedition of 1869. A few miles further down the Green River, Powell finds that this geographical feature is two buttes when viewed from the east, so it was renamed Buttes of the Cross. Buttes of the Cross towers over 1,400 feet above its surrounding terrain. It is situated 6.8 miles west of Candlestick Tower, and one-half mile outside the boundary of Canyonlands National Park.
The Sixshooter Peaks are two iconic sandstone summits located in Bears Ears National Monument in San Juan County, Utah, United States. The larger and higher North Sixshooter Peak rises to an elevation of 6,379 feet, whereas South Sixshooter Peak rises to 6,154 feet, with approximately 1.5 miles (2.4 km) separation between the two. These buttes tower nearly 1,400 feet above the surrounding terrain, and are historic landmarks visible from State Route 211 between Newspaper Rock and the Needles District of Canyonlands National Park. They are situated 1.5 mile outside the boundary of the park, and four miles northwest of Bridger Jack Butte. Variant names for the peaks include "North Six-Shooter Peak", "South Six-shooter Peak", "Six Shooter Peaks", and "Six-shooter Peak". They are so named because of their resemblance to a pair of revolvers pointing skyward.
Bridger Jack Butte is a sandstone butte located in Bears Ears National Monument, in San Juan County, Utah, United States. Set at the northern tip of Bridger Jack Mesa and above the confluence of Indian and Lavender Creeks, the summit rises to an elevation of 5,890 feet, and towers over 700 feet above the surrounding terrain and floor of Lavender Canyon to its west. This landmark is situated four miles southeast of the Sixshooter Peaks, and is visible from State Route 211 between Newspaper Rock and the Needles District of Canyonlands National Park. "Bridger Jack" was a Paiute medicine man.
Kissing Couple is a 5,815-foot-elevation (1,772-meter) sandstone pillar located in Colorado National Monument, in Mesa County of western Colorado, United States. This iconic 400-foot-high tower is situated on the west side of Monument Canyon, 1.5 mile southeast of the monument's visitor center, and 9 miles (14 km) west of the community of Grand Junction. It is also a half-mile south-southeast of another popular climbing destination, Independence Monument, and both can be seen from viewpoints along Rim Rock Drive. It is so named because it resembles an embracing couple. This geographical feature's name was officially adopted in 1982 by the United States Board on Geographic Names. Older USGS maps have the feature's name misplaced by about one-half mile to the southeast. The first ascent of the summit was made May 4, 1960, by Layton Kor, Harvey Carter, and John Auld via the five pitch, class 5.11a route named Long Dong Wall. The first free ascent was made in 1977 by Andy Petefish, Tom Stubbs, and Jim Pearson. Some climbers alternatively refer to Kissing Couple as "Bell Tower."
