Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Powderville, Montana
Powderville, also Elkhorn Crossing is an unincorporated community in northeastern Powder River County, Montana, United States, along the Powder River. It is a small cluster of buildings that lies along local roads northeast of the town of Broadus, the county seat of Powder River County. Its elevation is 2,828 feet (862 m). History On September 7, 1865, the right and middle columns of the Powder River Expedition crossed the future site of Powderville while traveling south upriver. That evening, the columns camped several miles to the south and buried three soldiers who had died during the day. The Powder River Telegraph Station was a U.S. Army telegraph repair station that existed from 1878 until 1883 along the Powder River in southeastern Montana Territory. Today the site is within Powder River County. The Powder River Telegraph Repair Station was established on November 1, 1878 by soldiers of the 9th U.S. Infantry from Camp Devin on the right bank of the Powd ...

Carter County, Montana
Carter County is a County (United States), county located in the U.S. state of Montana. As of the 2020 United States census, 2020 census, the population was 1,415, making it the seventh-least populous county in Montana. The county seat is Ekalaka, Montana, Ekalaka. History Carter County was named for Thomas H. Carter, Thomas Henry Carter, the state's first congressman (representative in Congress from the Montana Territory, followed by first representative from the state of Montana to the US House of Representatives). Prior to settlement the land of Carter County was occupied by the Sioux Indians, Sioux tribe. Geography According to the United States Census Bureau, the county has a total area of , of which is land and (0.2%) is water. Medicine Rocks State Park is located 14 miles north of Ekalaka. Weathering has given the rocks an unusual texture. The site was used by Indian hunting parties. Adjacent counties * Powder River County, Montana, Powder River County - west * Cust ...

List Of Mountain Ranges In Montana
This is a list of mountain ranges in the state of Montana. Montana is the fourth largest state in the United States and is well known for its mountains. The name "Montana" means "mountainous" in Latin. Representative James Mitchell Ashley ( R-Ohio), suggested the name when legislation organizing the territory was passed by the United States Congress in 1864. Ashley noted that a mining camp in the Colorado Territory had already used the name, and Congress agreed to use the name for the new territory. According to the United States Board on Geographic Names, there are at least 100 named mountain ranges and sub-ranges in Montana. However, mountain ranges have no official boundaries, and there is no official list of mountain ranges in the state. List of mountain ranges The mountain ranges below are listed by name, county, coordinates, and average elevation as recorded by the U.S. Geological Survey. Sub-ranges are indented below the name of the primary range. Some of these ranges exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Island Range
An island range is a mountain range that exists in total or almost total isolation from a larger chain of ranges and sub-ranges. From a distance on the plains, these ranges appear as "islands" of higher ground. They are often described as islands of mountainous land because they exist in the "sea" of lower elevation and flatter prairie country; many examples are found in the northern Rocky Mountains of the United States. Island ranges include the Big Snowy Mountains of east-central Montana, the Crazy Mountains of south-central Montana, or the Wichita Mountains of southwestern Oklahoma. Island ranges, due to their isolation, often have animal and/or plant species or subspecies found nowhere else. See also *Island biogeography *Sky island Sky islands are topographic isolation, isolated mountains surrounded by radically different lowland environments. The term originally referred to those found on the Mexican Plateau, and has extended to similarly isolated montane ecosystems, ...

Sky Island
Sky islands are topographic isolation, isolated mountains surrounded by radically different lowland environments. The term originally referred to those found on the Mexican Plateau, and has extended to similarly isolated montane ecosystems, high-elevation forests. The isolation has significant implications for these natural habitats. The Southwestern United States, American Southwest region began warming up between and 10,000 years Before Present, BP and atmospheric temperatures increased substantially, resulting in the formation of vast deserts that isolated the sky islands. Endemism, altitudinal migration, and Relict (biology), relict populations are some of the natural phenomena to be found on sky islands. The complex dynamics of species richness on sky islands draws attention from the discipline of biogeography, and likewise the biodiversity is of concern to conservation biology. One of the key elements of a sky island is separation by physical distance from the other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Ranges Of Montana
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
