Citadel Peaks
Citadel Peaks is a mountain ridge located in the Goat Haunt area of Glacier National Park, in Glacier County of the U.S. state of Montana. This arête with a row of sharp points is part of the Livingston Range, and is approximately four miles east of the Continental Divide. Neighbors include Olson Mountain, to the north, Mount Cleveland to the east, and Kootenai Peak to the south. Topographic relief is significant as Citadel Peaks rises over above Waterton Lake in less than two miles, and above Lake Janet in one mile. Precipitation runoff from the mountain drains to the south end of Waterton Lake. The first ascent of Citadel Spire, a major pinnacle on the ridge, was made in 1967 by Jerry Kanzler, Jim Kanzler, Ray Martin, and Clare Pogreba. This geographical feature's name was officially adopted in 1929 by the United States Board on Geographic Names. To the Pikuni people, Citadel Peaks is known as "Ataniawxis", meaning "The Needles".Erik Molvar, ''Best Easy Day Hikes Glacie ...

Olson Mountain
Olson Mountain, also known as Mount Olson, is a 7,913-foot-elevation (2,412 m) mountain summit located in the Livingston Range, of Glacier National Park in the U.S. state of Montana. Olson Mountain rises more than above the western shore of Waterton Lake. The mountain was named for a surveyor on the International Boundary Survey, with the name officially adopted in 1929. The nearest higher peak is Campbell Mountain, to the north, and Citadel Peaks is two miles (3.2 km) to the south. Precipitation runoff from the mountain drains into Olson Creek before it empties to Waterton Lake. Climate Based on the Köppen climate classification, Olson Mountain is located in a subarctic climate zone characterized by long, usually very cold winters, and short, cool to mild summers. Temperatures can drop below −10°F with wind chill factors below −30°F. Geology Like other mountains in Glacier National Park, Olson Mountain is composed of sedimentary rock laid down during the Precambrian ...

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] |
Sedimentary Rock
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Piikani Nation
The Piikani Nation (, formerly the Peigan Nation) ( bla, Piikáni) is a First Nation (or an Indian band as defined by the ''Indian Act''), representing the Indigenous people in Canada known as the Northern Piikani ( bla, script=Latn, Aapátohsipikáni) or simply the Peigan ( or ). History Historically speaking the Blackfoot language and members of the Blackfoot Confederacy (), the Peigan people occupied territory before the 1870s on both sides of what is now the Canada–United States border. The Blackfoot Confederacy signed several treaties with the US and received the Great Northern Reservation, an initially vast reservation in present-day Montana. However, 220 Peigans were massacred by the US Army in 1870 and American authorities pressured the Blackfoot to give up more and more lands to settlers ( were ceded in 1887), leading some Peigans to relocate to Canada and sign Treaty 7 with the Canadian government in 1877. The Peigan are now divided between the Blackfeet Nation ( or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Ascent
In mountaineering, a first ascent (abbreviated to FA in guide books) is the first successful, documented attainment of the top of a mountain or the first to follow a particular climbing route. First mountain ascents are notable because they entail genuine exploration, with greater risks, challenges and recognition than climbing a route pioneered by others. The person who performs the first ascent is called the first ascensionist. In free climbing, a first ascent (or first free ascent, abbreviated FFA) of a climbing route is the first successful, documented climb of a route without using equipment such as anchors or ropes for aiding progression or resting. History The details of the first ascents of even many prominent mountains are scanty or unknown; sometimes the only evidence of prior summiting is a cairn, artifacts, or inscriptions at the top. Today, first ascents are generally carefully recorded and usually mentioned in guidebooks. The term is also used when referrin ...

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Waterton Lake
Waterton Lake is a mountain lake in southern Alberta, Canada and northern Montana, United States. The lake is composed of two bodies of water, connected by a shallow channel known locally as the Bosporus. The two parts are referred to as Middle Waterton Lake, and Upper Waterton Lake, the latter of which is divided by the Canada–United States border with Canada containing about two thirds of the lake while the Southern third falls in the United States. The Boundary Commission Trail ends at the lake as the last border marker was placed there on 8 August 1874. The United States Geological Survey gives the geocoordinates of for Upper Waterton Lake. Lower Waterton Lake is north of Middle Waterton Lake and is separated by a channel known as the Dardanelles. The northern, lower end of the main lake lies in Waterton Lakes National Park while the upper, southern part of the lake is located in Glacier National Park. In 1979, UNESCO established the ''Waterton Biosphere Reserve'' to protec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
