Precipitation depends on elevation with lower areas in the Big Horn Basin averaging 5–8 inches (130–200 mm), making the area nearly a true desert . The lower areas in the North and on the eastern plains typically average around 10–12 inches (250–300 mm), making the climate there semi-arid . Some mountain areas do receive
1728-610: Is generally semi-arid and continental ( Köppen climate classification BSk ) and is drier and windier in comparison to most of the United States with greater temperature extremes. Much of this is due to the topography of the state. Summers in Wyoming are warm with July high temperatures averaging between 80 and 90 °F (27 and 32 °C) in most of the state. With increasing elevation, however, this average drops rapidly with locations above 9,000 feet (2,700 m) averaging around 70 °F (21 °C). Summer nights throughout

Other more northerly mountain ranges of the eastern Canadian Cordillera continue beyond the Liard River valley, including
3780-508: The North American plate . The angle of subduction was shallow, resulting in a broad belt of mountains running down western North America. Since then, further tectonic activity and erosion by glaciers have sculpted the Rockies into dramatic peaks and valleys. At the end of the last ice age , humans began inhabiting the mountain range. After explorations of the range by Europeans, such as Sir Alexander Mackenzie , and Anglo-Americans, such as
3888-621: The Paleozoic , western North America lay underneath a shallow sea, which deposited many kilometers of limestone and dolomite . In the southern Rockies, near present-day Colorado, these ancestral rocks were disturbed by mountain building approximately 300 Ma , during the Pennsylvanian . This mountain-building produced the Ancestral Rocky Mountains. They consisted largely of Precambrian metamorphic rock forced upward through layers of

Non-denominational Protestants had an adherence rate of 40.58 per 1,000 people; these trends reflected
8208-474: The forty years 1972–2012. Jackson, Wyoming , increased 260%, from 1,244 to 4,472 residents, in those forty years. The rocks in the Rocky Mountains were formed before the mountains were raised by tectonic forces. The oldest rock is Precambrian metamorphic rock that forms the core of the North American continent. There is also Precambrian sedimentary argillite , dating back to 1.7 billion years ago. During
8316-584: The last sixty million years, erosion stripped away the high rocks, revealing the ancestral rocks beneath, and forming the current landscape of the Rockies. Periods of glaciation occurred from the Pleistocene Epoch (1.8 million – 70,000 years ago) to the Holocene Epoch (fewer than 11,000 years ago). These ice ages left their mark on the Rockies, forming extensive glacial landforms, such as U-shaped valleys and cirques . Recent glacial episodes included
8424-509: The limestone laid down in the shallow sea. The mountains eroded throughout the late Paleozoic and early Mesozoic , leaving extensive deposits of sedimentary rock . Terranes began colliding with the western edge of North America in the Mississippian (approximately 350 million years ago), causing the Antler orogeny . For 270 million years, the focus of the effects of plate collisions were near
8532-524: The loss of recreational opportunities. The analysis also revealed that cleanup of the river could yield $ 2.3 million in additional revenue from recreation. In 1983, the former owner of the zinc mine was sued by the Colorado Attorney General for the $ 4.8 million cleanup costs; five years later, ecological recovery was considerable. The Rocky Mountains contain several sedimentary basins that are rich in coalbed methane . Coalbed methane

The name of the mountains is a calque of an Algonquian name, specifically Plains Cree ᐊᓯᓃᐘᒋᐩ asinîwaciy (originally transcribed as-sin-wati ), literally "rocky mountain / alp". The first mention of their present name by
8964-450: The normal 300 to 500 kilometres (200 to 300 mi). Scientists hypothesize that the shallow angle of the subducting plate increased the friction and other interactions with the thick continental mass above it. Tremendous thrusts piled sheets of crust on top of each other, building the broad, high Rocky Mountain range. The current southern Rockies were forced upwards through the layers of Pennsylvanian and Permian sedimentary remnants of
9072-638: The northern peaks. Average January temperatures can range from −7 °C (20 °F) in Prince George, British Columbia, to 6 °C (43 °F) in Trinidad, Colorado . Therefore, there is no single monolithic ecosystem for the entire Rocky Mountain Range. Instead, ecologists divide the Rockies into a number of biotic zones . Each zone is defined by whether it can support trees and the presence of one or more indicator species . Two zones that do not support trees are

In Colorado, along with the crest of the Continental Divide, rock walls that Native Americans built for driving game date back 5,400–5,800 years. A growing body of scientific evidence indicates that indigenous people had significant effects on mammal populations by hunting and on vegetation patterns through deliberate burning. Recent human history of

Economic resources of the Rocky Mountains are varied and abundant. Minerals found in the Rocky Mountains include significant deposits of copper, gold, lead, molybdenum , silver, tungsten , and zinc . The Wyoming Basin and several smaller areas contain significant reserves of coal, natural gas, oil shale , and petroleum. For example,
9828-977: The soil and eventually evaporates. Several rivers begin in or flow through the state, including the Yellowstone River, Bighorn River, Green River, and the Snake River. Much of Wyoming is covered with large basins containing different eco-regions, from shrublands to smaller patches of desert. Regions of the state classified as basins contain everything from large geologic formations to sand dunes and vast unpopulated spaces. Basin landscapes are typically at lower elevations and include rolling hills, valleys, mesas, terraces and other rugged terrain, but also include natural springs as well as rivers and artificial reservoirs. They have common plant species such as various subspecies of sagebrush , juniper and grasses such as wheatgrass , but basins are known for their diversity of plant and animal species. Wyoming has 32 named islands;

Sparsely populated, Wyoming is the least populous state of the United States. Wyoming has the second-lowest population density in
10800-632: The terranes and subduction are the foot pushing the rug, the ancestral rocks are the rug, and the Canadian Shield in the middle of the continent is the hardwood floor. Further south, an unusual subduction may have caused the growth of the Rocky Mountains in the United States, where the Farallon Plate dove at a shallow angle below the North American Plate . This low angle moved the focus of melting and mountain building much farther inland than
10908-798: The territory protected by the Yellowstone Timberland Reserve . President Grover Cleveland 's 1897 proclamation established a protected area encompassing the northern end of Jackson Hole , extending from the south boundary of the Yellowstone Forest Reserve south to the area of the Gros Ventre River , and from the Idaho border in the west to the area of the Continental Divide in the east.
