The Mogollon Rim is a topographical and geological feature cutting across the northern half of the U.S. state of Arizona. It extends approximately 200 miles (320 km), starting in northern Yavapai County and running eastward, ending near the border with New Mexico. It forms the southern edge of the Colorado Plateau in Arizona.
The Cumberland Plateau is the southern part of the Appalachian Plateau in the Appalachian Mountains of the United States. It includes much of eastern Kentucky and Tennessee, and portions of northern Alabama and northwest Georgia. The terms "Allegheny Plateau" and the "Cumberland Plateau" both refer to the dissected plateau lands lying west of the main Appalachian Mountains. The terms stem from historical usage rather than geological difference, so there is no strict dividing line between the two. Two major rivers share the names of the plateaus, with the Allegheny River rising in the Allegheny Plateau and the Cumberland River rising in the Cumberland Plateau in Harlan County, Kentucky.
The geology of the Grand Canyon area includes one of the most complete and studied sequences of rock on Earth. The nearly 40 major sedimentary rock layers exposed in the Grand Canyon and in the Grand Canyon National Park area range in age from about 200 million to nearly 2 billion years old. Most were deposited in warm, shallow seas and near ancient, long-gone sea shores in western North America. Both marine and terrestrial sediments are represented, including lithified sand dunes from an extinct desert. There are at least 14 known unconformities in the geologic record found in the Grand Canyon.
The geology of the Zion and Kolob canyons area includes nine known exposed formations, all visible in Zion National Park in the U.S. state of Utah. Together, these formations represent about 150 million years of mostly Mesozoic-aged sedimentation in that part of North America. Part of a super-sequence of rock units called the Grand Staircase, the formations exposed in the Zion and Kolob area were deposited in several different environments that range from the warm shallow seas of the Kaibab and Moenkopi formations, streams and lakes of the Chinle, Moenave, and Kayenta formations to the large deserts of the Navajo and Temple Cap formations and dry near shore environments of the Carmel Formation.
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 Highland Rim is a geographic term for the area in Tennessee surrounding the Central Basin. Nashville is largely surrounded by higher terrain in all directions.
Montana State University Billings is a public university in Billings, Montana. It is the state's third largest university. Its campus is located on 110 acres in downtown Billings. Formerly Eastern Montana Normal School at its founding in 1927, the Normal School changed its name to Eastern Montana College of Education in 1949. It was again renamed in 1965 as Eastern Montana College (EMC). It merged into the Montana University System in 1994 under its present name. Currently, the university offers over 100 specialized programs for certificates, associate, bachelor's, and master's degrees through the University's five colleges. The five colleges of Montana State University Billings are Liberal Arts & Social Sciences, Business, Health Professions and Science, Education, and City College.
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.
Rimrock is the sheer rock wall at the upper edge of a plateau, canyon, or geological uplift. It may refer to either the rock formation or to the rock itself. Rimrock may be composed of almost any stone—basalt, gneiss, granite, sandstone, etc.—and is frequently layered. Many times it overlays a softer stone which erodes away underneath. American Indians in the West often used cavities found below rimrock to construct dwellings and granaries.
Gloucestershire is one of the most geologically and scenically diverse counties in England, with rocks from the Precambrian through to the Jurassic represented. These varying rock-types are responsible for the three major areas of the county, each with its own distinctive scenery and land-use - the Forest of Dean in the west, bordering Wales, the Cotswolds in the east, and in between, the Severn Vale.
Interstate 90 (I-90) is an east–west transcontinental Interstate highway across the northern United States, linking Seattle to Boston. The portion in the state of Montana is 554.10 miles (891.74 km) in length, passing through fourteen counties in central and southern Montana. Due to the large size of Montana, it is the longest segment of Interstate 90 within a single state.
The Geology of Yorkshire in northern England shows a very close relationship between the major topographical areas and the geological period in which their rocks were formed. The rocks of the Pennine chain of hills in the west are of Carboniferous origin whilst those of the central vale are Permo-Triassic. The North York Moors in the north-east of the county are Jurassic in age while the Yorkshire Wolds to the south east are Cretaceous chalk uplands. The plain of Holderness and the Humberhead levels both owe their present form to the Quaternary ice ages. The strata become gradually younger from west to east.
Medicine Rocks State Park is a park owned by the state of Montana in the United States. It is located about 25 miles (40 km) west-southwest of Baker, Montana, and 11 miles (18 km) north of Ekalaka, Montana. The park is named for the "Medicine Rocks," a series of sandstone pillars similar to hoodoos some 60 to 80 feet high with eerie undulations, holes, and tunnels in them. The rocks contain numerous examples of Native American rock art and are considered a sacred place by Plains Indians. As a young rancher, future president Theodore Roosevelt said Medicine Rocks was "as fantastically beautiful a place as I have ever seen." The park is 330 acres (130 ha) in size, sits at 3,379 feet (1,030 m) in elevation, and is managed by the Montana Department of Fish, Wildlife and Parks. It was listed on the National Register of Historic Places in 2017 and designated as a certified International Dark Sky Sanctuary in 2020.
A destructive EF2 tornado hit Billings, Montana on Sunday, June 20, 2010. Known as the 2010 Father's Day tornado, the strong tornado was on the ground for about 12 minutes and took the roof off the Rimrock Auto Arena at MetraPark, a 10,000 seat arena, and heavily damaged numerous businesses. The storm was accompanied by high winds and a major hail storm that caused severe damage and flash flooding in the Heights section of the city. It was the first time since 1958 that a significant tornado struck the Downtown Billings area.
The Middle Permian Toroweap Formation is a thin, darker geologic unit, between the brighter colored units of the Kaibab Limestone above, and Coconino Sandstone below. It is a prominent unit in Grand Canyon, Arizona, USA, found through sections of the South Rim, Grand Canyon, and the North Rim, of the Kaibab Plateau; also the Kaibab's southeast extension to Cape Royal, the Walhalla Plateau. The Colorado River of the Grand Canyon makes its excursion from due-south to due-west around the Walhalla Plateau, as it enters the east end of the Grand Canyon's interior, Granite Gorge. The formation is also found in southeast Utah.
Coburn Hill is located 4.2 miles (7 km) southeast of Billings, Montana in Yellowstone County. Its most predominant feature is Sacrifice Cliffs, part of the Rimrocks surrounding the city. Another feature is several radio and television broadcast towers located on the hill.
The Shinarump Conglomerate is a geologic formation found in the Four Corners region of the United States. It was deposited in the early part of the Late Triassic period.
The geology of Norfolk in eastern England largely consists of late Mesozoic and Cenozoic sedimentary rocks of marine origin covered by an extensive spread of unconsolidated recent deposits.
