The following is a partial list of rock formations in the United States, organized by state.
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.
A monolith is a geological feature consisting of a single massive stone or rock, such as some mountains. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous or metamorphic rock. Some monoliths are volcanic plugs, solidified lava filling the vent of an extinct volcano.
In geomorphology, a butte is an isolated hill with steep, often vertical sides and a small, relatively flat top; buttes are smaller landforms than mesas, plateaus, and tablelands. The word butte comes from the French word butte, meaning knoll ; its use is prevalent in the Western United States, including the southwest where mesa is used for the larger landform. Due to their distinctive shapes, buttes are frequently landmarks in plains and mountainous areas. To differentiate the two landforms, geographers use the rule of thumb that a mesa has a top that is wider than its height, while a butte has a top that is narrower than its height.
Rainbow Bridge is a natural arch in southern Utah, United States. With a span of 275 feet (84 m), as reported in 1974 by the Bureau of Reclamation, and height of 290 feet (88 m), it is one of the largest natural arches in the world. 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. Rainbow Bridge National Monument was protected in 1910, and it is administered by Glen Canyon National Recreation 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 San Rafael Swell is a large geologic feature located in south-central Utah, United States 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.
Northern Arizona is an unofficial, colloquially-defined region of the U.S. state of Arizona. Generally consisting of Apache, Coconino, Mohave, Navajo, and Yavapai counties, the region is geographically dominated by the Colorado Plateau, the southern border of which in Arizona is called the Mogollon Rim.
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
Areas of Critical Environmental Concern (ACEC) is a conservation ecology program in the Western United States, managed by the Bureau of Land Management (BLM). The ACEC program was conceived in the 1976 Federal Lands Policy and Management Act (FLPMA), which established the first conservation ecology mandate for the BLM. The FLPMA mandate directs the BLM to protect important riparian corridors, threatened and endangered species habitats, cultural and archeological resources, as well as unique scenic landscapes that the agency assesses as in need of special management attention.
Arches National Park is a national park in eastern Utah, United States. The park is adjacent to the Colorado River, 4 mi (6 km) north of Moab, Utah. The park contains more than 2,000 natural sandstone arches, including the well-known Delicate Arch, which constitute the highest density of natural arches in the world. It also contains a variety of other unique geological resources and formations. The national park lies above an underground evaporite layer or salt bed, which is the main cause of the formation of the arches, spires, balanced rocks, sandstone fins, and eroded monoliths in the area.
Missouri Buttes or Little Missouri Buttes are located in Crook County in northeast Wyoming on the northwest flank of the Black Hills Uplift. The buttes are 3.5 miles (5.6 km) northwest (N60°W) of Devils Tower between the Little Missouri and the Belle Fourche rivers.
Windows Spotlight is a feature included with Windows 10 and Windows 11 which downloads images and advertisements from Bing and displays them as background wallpapers on the lock screen. In 2017, Microsoft began adding location information for many of the photographs.
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.
