Gregory Natural Bridge is a typically submerged natural arch that exists at Lake Powell in Utah. Before it was submerged in 1969, it had a span of 127 feet. Due to a long term regional drought, in 2021 the bridge was no longer submerged for the first time since the initial filling of the reservoir. [1]
Powell County is a county located in the U.S. Commonwealth of Kentucky. As of the 2020 census, the population was 13,129. Its county seat is Stanton. The county was formed January 7, 1852, by Kentucky Governor Lazarus W. Powell from parts of Clark, Estill, and Montgomery counties. It is no longer a dry county as of 2018. Powell County is home to Natural Bridge State Resort Park and the Red River Gorge Geologic Area, two of Kentucky's most important natural areas and ecotourism destinations, as well as the Pilot Knob State Nature Preserve.
Blanding is a city in San Juan County, Utah, United States. The population was 3,375 at the 2010 census, making it the most populated city in San Juan County. It was settled in the late 19th century by Mormon settlers, predominantly from the famed Hole-In-The-Rock expedition. Economic contributors include mineral processing, mining, agriculture, local commerce, tourism, and transportation.
Rainbow Bridge National Monument is administered by Glen Canyon National Recreation Area, southern Utah, United States. Rainbow Bridge is often described as the world's highest natural bridge. The span of Rainbow Bridge was reported in 1974 by the Bureau of Reclamation to be 275 feet (84 m). At the top it is 42 feet (13 m) thick and 33 feet (10 m) wide. The bridge, which is of cultural importance to a number of area Native American tribes, has been designated a Traditional Cultural Property by the National Park Service.
Lake Powell is an artificial reservoir on the Colorado River in Utah and Arizona, United States. It is a major vacation destination visited by approximately two million people every year. It is the second largest artificial 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, 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, 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 Dirty Devil River is an 80-mile-long (130 km) tributary of the Colorado River, located in the U.S. state of Utah. It flows through southern Utah from the confluence of the Fremont River and Muddy Creek before emptying into the Colorado River at Lake Powell.
Glen Canyon is a natural canyon carved by a 169.6-mile (272.9 km) length of the Colorado River, mostly in southeastern and south-central Utah, in the United States. Glen Canyon starts where Narrow Canyon ends, at the confluence of the Colorado River and the Dirty Devil River. A small part of the lower end of Glen Canyon extends into northern Arizona and terminates at Lee's Ferry, near the Vermilion Cliffs. Like the Grand Canyon farther downstream, Glen Canyon is part of the immense system of canyons carved by the Colorado River and its tributaries.
Horseshoe Bend is a horseshoe-shaped incised meander of the Colorado River located near the town of Page, Arizona, United States. It is also referred to as the "east rim of the Grand Canyon."
State Route 276 is a state highway in remote portions of San Juan County, eastern Garfield County, and Kane County, in the southeast of the U.S. state of Utah. The route is used as an access to Lake Powell, serving the small resort towns of Ticaboo and Bullfrog. Historically, SR-276 crossed Lake Powell via the Charles Hall Ferry, the only auto ferry in the state of Utah; however, the ferry is currently out of service due to low water levels. The entire route is part of the Trail of the Ancients National Scenic Byway. Lake Powell separates the route into two sections; the eastern section was numbered State Route 263 prior to the existence of the ferry.
Bolshoy Kamenny Bridge is a steel arch bridge spanning Moskva River at the western end of the Moscow Kremlin. Its predecessor was the first permanent stone bridge in Moscow, Russia. The existing bridge was completed in 1938 by engineer Nikolai Kalmykov.
Music Temple is a geological feature near the Colorado River in Glen Canyon, southern Utah, on the Navajo Nation, United States, which consists of a grotto with high, vaulting walls and a deep central pool of water.
Cataract Canyon is a 46-mile-long (74 km) canyon of the Colorado River located within Canyonlands National Park and Glen Canyon National Recreation Area in southern Utah. It begins at Colorado's confluence with the Green River, and its downstream terminus is the confluence with the Dirty Devil River. The lower half of the canyon is submerged beneath Lake Powell when the lake is at its normal high water elevation of 3,700 feet (1,100 m).
The Hite Crossing Bridge is an arch bridge that carries Utah State Route 95 across the Colorado River northwest of Blanding, Utah, United States. The bridge informally marks the upstream limit of Lake Powell and the end of Cataract Canyon of the Colorado River, but when the lake is at normal water elevation, the water can back up over 30 miles (48 km) upstream into Cataract Canyon. The bridge is the only automobile bridge spanning the Colorado River between the Glen Canyon Bridge, 185 miles (298 km) downstream near the Glen Canyon Dam and the U.S. Route 191 bridge 110 miles (180 km) upstream near Moab. The bridge is near Hite Marina on Lake Powell, and a small airstrip is immediately adjacent to the north side of the bridge.
Darwin's Arch was a natural rock arch feature to the south-east of Darwin Island in the Galápagos Archipelago in the Pacific Ocean, and is now a pillar formation. The arch sat on an irregularly shaped, rocky, submerged plateau, nicknamed "the theatre". The arch collapsed into the sea on 17 May 2021 from natural erosion.
Yellowstone Natural Bridge is a natural arch in Yellowstone National Park, Wyoming. The arch is at an elevation of 7,983 feet (2,433 m) and can be reached by hiking a little more than a mile from the Bridge Bay marina parking lot. The arch is 51 feet (16 m) tall and was created as water eroded through the surrounding rhyolite rock.
The Cathedral in the Desert is a natural formation, sometimes referred to as an amphitheater, buried under Lake Powell in Glen Canyon. Due to the Southwestern North American megadrought, the cathedral has been visible in 2005 and 2019. Lake Powell must drop to 3,605 feet for the cathedral floor to be visible.
