Sentinel Mountain (Montana)
Sentinel Mountain is an 8,245-foot-elevation (2,513 meter) summit in Glacier County, Montana, United States. Description Sentinel Mountain is located south of the Canada–United States border in the Belly River area of Glacier National Park. It is situated in the Lewis Range, seven miles northwest of landmark Chief Mountain, and approximately 15 miles east of the Continental Divide. Precipitation runoff from the mountain drains into tributaries of the Belly River. Topographic relief is significant as the summit rises nearly above the North Fork Belly River in one mile. The mountain's toponym was officially adopted in 1929 by the United States Board on Geographic Names. Geology Like other mountains in Glacier National Park, Sentinel Mountain is composed of sedimentary rock laid down during the Precambrian to Jurassic periods. Formed in shallow seas, this sedimentary rock was initially uplifted beginning 170 million years ago when the Lewis Overthrust fault pus ...

Jurassic
The Jurassic ( ) is a Geological period, geologic period and System (stratigraphy), stratigraphic system that spanned from the end of the Triassic Period million years ago (Mya) to the beginning of the Cretaceous Period, approximately Mya. The Jurassic constitutes the middle period of the Mesozoic, Mesozoic Era and is named after the Jura Mountains, where limestone strata from the period were first identified. The start of the Jurassic was marked by the major Triassic–Jurassic extinction event, associated with the eruption of the Central Atlantic magmatic province, Central Atlantic Magmatic Province. The beginning of the Toarcian Stage started around 183 million years ago and is marked by an extinction event associated with widespread Anoxic event, oceanic anoxia, ocean acidification, and elevated temperatures likely caused by the eruption of the Karoo-Ferrar, Karoo-Ferrar large igneous provinces. The end of the Jurassic, however, has no clear boundary with the Cretaceous and i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Glacier National Park (U
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 ...

Sofa Mountain
Sofa Mountain is a 2,515-meter (8,251-foot) summit located in Waterton Lakes National Park, in Alberta, Canada. It is part of the Lewis Range which is a subset of the Canadian Rockies, and is the easternmost mountain in the Canadian Rockies, as well as the park. It is situated east of Vimy Peak, and the nearest higher neighbor is Crypt Peak, to the southwest. Topographic relief is significant as the north aspect rises over 1,220 meters (4,000 feet) above Middle Waterton Lake in approximately six kilometers (3.7 mi). History The mountain was named in 1865 by Kootenay Brown who wrote: "Coming down from the mountain, where we got our first glimpse of the buffalo, we soon reached the prairie shore of a large lake at the further side of which a mountain rose to a sofa-like peak among the clouds. This mountain was afterwards called Sofa Mountain."Dave Birrell, ''50 Roadside Panoramas in the Canadian Rockies'', Rocky Mountain Books, 2000, , page 151. This mountain's name w ...

Chief Mountain Border Crossing
The Chief Mountain Border Crossing connects the town of Babb, Montana with Pincher Creek, Alberta on the Canada–US border. Montana Highway 17 on the American side joins Alberta Highway 6 on the Canadian side, creating the only road border crossing within the Waterton-Glacier International Peace Park. Poker Creek–Little Gold Creek and this crossing are the only ones closed in winter. Canadian side The idea for this road link, which would reduce the connection between Waterton Lakes National Park and Glacier National Park (U.S.) by about , was suggested as early as 1915. To provide employment during the Great Depression, relief work camps operated from late 1932 to 1935, by which time the highway was almost complete. Called the Kennedy Creek Cut Off or Kennedy Creek-Belly River Road during construction, the agreed name of The Chief Mountain International Highway was suggested by Herbert Legg of Canada Customs. No formal ceremony marked the opening in June 1936. When Legg had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of The Rocky Mountains
The geology of the Rocky Mountains is that of a discontinuous series of mountain ranges with distinct geological origins. Collectively these make up the Rocky Mountains, a mountain system that stretches from Northern British Columbia through central New Mexico and which is part of the great mountain system known as the North American Cordillera. The rocky cores of the mountain ranges are, in most places, formed of pieces of continental crust that are over one billion years old. In the south, an older mountain range was formed 300 million years ago, then eroded away. The rocks of that older range were reformed into the Rocky Mountains. The Rocky Mountains took shape during an intense period of plate tectonic activity that resulted in much of the rugged landscape of the western North America. The Laramide orogeny, about 80–55 million years ago, was the last of the three episodes and was responsible for raising the Rocky Mountains. Subsequent erosion by glaciers has created the ...

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should ave ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
