This Ecoregion is located almost entirely within the western and central portions of the US state of Wyoming, but does extend minimally into southeastern Idaho, south-central Montana, north-central Utah and northwestern Colorado. It is located within multiple high altitude intermontane basins largely surrounded by various subranges of the Rocky Mountains | Wyoming Basin shrub steppe |
3,781 | The Y P Desert is a desert and ecoregion, within the deserts and xeric shrublands biome, in Owyhee County, Idaho, and Elko County, Nevada in the northwestern United States.
The Y P Desert lies at the eastern edges of the Owyhee Desert, and is home to the South Fork Owyhee River Recreation Area.
Josephine Reservoir, a small reservoir, Hat Peak, and the Duck Valley Indian Reservation are at the eastern perimeter of the Y P Desert | Y P Desert |
3,782 | The Yuma Desert is a lower-elevation section of the Sonoran Desert in the southwestern United States and the northwest of Mexico. It lies in the Salton basin. The desert contains areas of sparse vegetation and has notable areas of sand dunes | Yuma Desert |

3,784 | The richly textured landscape of the United States is a product of the dueling forces of plate tectonics, weathering and erosion. Over the 4. 5 billion-year history of the Earth, tectonic upheavals and colliding plates have raised great mountain ranges while the forces of erosion and weathering worked to tear them down | Geology of the United States |
3,785 | The Geology of Washington, D. C. , is broadly divisible into two regions | Geology of Washington, D.C. |
3,786 | The geology of American Samoa is part of the broader geology of the Samoan island chain.
Geologic History & Origins
Except for Rose Atoll, the islands in the chain are geologically young, having formed within the last few million years, likely in the Pliocene or Quaternary. Preliminary mapping took place in the 1940s and 1950s, with a hiatus until the 1980s | Geology of American Samoa |
3,787 | The geology of Guam formed as a result of mafic, felsic and intermediate composition volcanic rocks erupting below the ocean, building up the base of the island in the Eocene, between 33. 9 and 56 million years ago. The island emerged above the water in the Eocene, although the volcanic crater collapsed | Geology of Guam |
3,788 | The geology of the Northern Mariana Islands began to form with undersea volcanic eruptions in the Eocene. Islands such as Saipan show a variety of rock types including volcanic rocks, breccia, tuff, conglomerate, sandstone, clay and extensive limestones.
Geologic History, Stratigraphy & Tectonics
The bulk of geological research in the Northern Mariana Islands has focused on the large, populous island of Saipan | Geology of the Northern Mariana Islands |
3,789 | The geology of the U. S. Virgin Islands includes mafic volcanic rocks, with complex mineralogy that first began to erupt in the Mesozoic overlain and interspersed with carbonate and conglomerate units | Geology of the United States Virgin Islands |
3,790 | The Absaroka sequence was a cratonic sequence that extended from the end of the Mississippian through the Permian periods. It is the unconformity between this sequence and the preceding Kaskaskia that divides the Carboniferous into the Mississippian and Pennsylvanian periods in North America.
Like the Kaskaskia sequence, Absaroka sedimentary deposits were dominated by detrital or siliclastic rocks | Absaroka sequence |
3,791 | The Bone Wars, also known as the Great Dinosaur Rush, was a period of intense and ruthlessly competitive fossil hunting and discovery during the Gilded Age of American history, marked by a heated rivalry between Edward Drinker Cope (of the Academy of Natural Sciences of Philadelphia) and Othniel Charles Marsh (of the Peabody Museum of Natural History at Yale). Each of the two paleontologists used underhanded methods to try to outdo the other in the field, resorting to bribery, theft, and the destruction of bones. Each scientist also sought to ruin his rival's reputation and cut off his funding, using attacks in scientific publications | Bone Wars |
3,792 | Cameron's Line is an Ordovician suture fault in the northeast United States which formed as part of the continental collision known as the Taconic orogeny around 450 mya. Named after Eugene N. Cameron, who first described it in the 1950s, it ties together the North American continental craton, the prehistoric Taconic Island volcanic arc, and the bottom of the ancient Iapetus Ocean | Cameron's Line |
3,793 | The Canadian Shield (French: Bouclier canadien [buklje kanadjɛ̃]), also called the Laurentian Plateau, is a geologic shield, a large area of exposed Precambrian igneous and high-grade metamorphic rocks. It forms the North American Craton (or Laurentia), the ancient geologic core of the North American continent. Glaciation has left the area with only a thin layer of soil, through which exposures of igneous bedrock resulting from its long volcanic history are frequently visible | Canadian Shield |
3,794 | Carolina bays are elliptical to circular depressions concentrated along the East Coast of the United States within coastal New York, New Jersey, Delaware, Maryland, Virginia, North Carolina, South Carolina, Georgia, and north Florida. In Maryland, they are called Maryland basins. Within the Delmarva Peninsula, they and other coastal ponds are also called Delmarva bays | Carolina bays |
3,795 | Chernozem (from Russian: чернозём, tr. chernozyom, IPA: [tɕɪrnɐˈzʲɵm]; "black ground"), also called black soil, is a black-colored soil containing a high percentage of humus (4% to 16%) and high percentages of phosphorus and ammonia compounds. Chernozem is very fertile soil and can produce high agricultural yields with its high moisture storage capacity | Chernozem |
3,796 | The Deicke and Millbrig bentonite layers, specifically the potassium bentonite layer, K-bentonite, were formed from a volcanic eruption during the Taconic orogeny during the Late Ordovician on Laurentia, the craton of North America. Researchers are very interested in the eruptions that formed these bentonite layers because they are thought to be some of the largest volcanic eruptions in the last 600 million years of Earth history, and the resulting ash layer for each eruption individually was greater in volume than the Toba eruption. Bentonite is a type of clay that is formed from the weathering of volcanic ash deposits | Deicke and Millbrig bentonite layers |
3,797 | The Interior Plains is a vast physiographic region that spreads across the Laurentian craton of central North America, extending along the east flank of the Rocky Mountains from the Gulf Coast region to the Arctic Beaufort Sea. In Canada, it encompasses the Canadian Prairies separating the Canadian Rockies from the Canadian Shield, as well as the Boreal Plains and Taiga Plains east of the Mackenzie and Richardson Mountains; while in the United States, it includes the Great Plains of the West/Midwest and the tallgrass prairie region to the south of the Great Lakes extending east to the Appalachian Plateau region.
Geologic history
A series of tectonic plate collisions in the crust that formed the center of the North American continent laid the groundwork for the modern-day interior plains | Interior Plains |
3,798 | The Niagara Escarpment is a long escarpment, or cuesta, in Canada and the United States that starts from the south shore of Lake Ontario westward, circumscribes the top of the Great Lakes Basin running from New York through Ontario, Michigan, and Wisconsin. The escarpment is the cliff over which the Niagara River plunges at Niagara Falls, for which it is named.
The escarpment is a UNESCO World Biosphere Reserve | Niagara Escarpment |
3,799 | Within the petroleum industry, proven crude oil reserves in the United States was 44. 4 billion barrels (7. 06×109 m3) of crude oil as of the end of 2021, excluding the Strategic Petroleum Reserve | Oil reserves in the United States |
