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] |
Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...

Marten River
The Marten River is a short river in central Alberta. The Marten is one of the major inflows of Lesser Slave Lake, which drains through the Lesser Slave River, a major tributary of the Athabasca River. Significant debate exists regarding the origin of the river's name. One theory suggests the river, as well as nearby Marten Mountain were named for a local trapper. The other theory suggests the river and mountain were named for martens, a weasel that inhabits the region. The Geological Survey of Canada used the name ''Martin River'' on an 1892 map. The river forms to the north of Marten Mountain at the outlet of the westernmost Marten Lake. It flows southwest before passing under Alberta Highway 88. It enters Lesser Slave Lake at the northern tip of Lesser Slave Lake Provincial ParkMussio Ventures.''South Peace Alberta Mapbook.'' Burnaby: Backroad Mapbooks, 2004.

Boundary Ranges
The Boundary Ranges, also known in the singular and as the Alaska Boundary Range, are the largest and most northerly subrange of the Coast Mountains. They begin at the Nass River, near the southern end of the Alaska Panhandle in the Canadian province of British Columbia and run to the Kelsall River, near the Chilkoot Pass, beyond which are the Alsek Ranges of the Saint Elias Mountains, and northwards into the Yukon Territory flanking the west side of the Yukon River drainage as far as Champagne Pass, north of which being the Yukon Ranges. To their east are the Skeena Mountains and Stikine Plateau of the Interior Mountains complex that lies northwest of the Interior Plateau; the immediately adjoining subregion of the Stikine Plateau is the Tahltan Highland. To their northeast is the Tagish Highland, which is a subregion of the Yukon Plateau. Both highlands are considered in some descriptions as included in the Coast Mountains. The Alexander Archipelago lies offshore and is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coast Mountains
The Coast Mountains (french: La chaîne Côtière) are a major mountain range in the Pacific Coast Ranges of western North America, extending from southwestern Yukon through the Alaska Panhandle and virtually all of the Coast of British Columbia south to the Fraser River. The mountain range's name derives from its proximity to the sea coast, and it is often referred to as the Coast Range. The range includes volcanic and non-volcanic mountains and the extensive ice fields of the Pacific and Boundary Ranges, and the northern end of the volcanic system known as the Cascade Volcanoes. The Coast Mountains are part of a larger mountain system called the Pacific Coast Ranges or the Pacific Mountain System, which includes the Cascade Range, the Insular Mountains, the Olympic Mountains, the Oregon Coast Range, the California Coast Ranges, the Saint Elias Mountains and the Chugach Mountains. The Coast Mountains are also part of the American Cordilleraa Spanish term for an extensive chain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Misty Fjords National Monument
Misty Fjords National Monument (or Misty Fiords National Monument) is a national monument and wilderness area administered by the U.S. Forest Service as part of the Tongass National Forest. Misty Fiords is about east of Ketchikan, Alaska, along the Inside Passage coast in extreme southeastern Alaska, comprising of Tongass National Forest in Alaska's Panhandle. All but are designated as wilderness. Congress reserved the remainder for the Quartz Hill molybdenum deposit, possibly the largest such mineral deposit in the world. The national monument was originally proclaimed by President Jimmy Carter in December 1978 as ''Misty Fiords National Monument'', using the authorization of the Antiquities Act and became a part of an ongoing political struggle between the federal government and the State of Alaska over land use policy and authority that finally led to the Alaska National Interest Lands Conservation Act in 1980. In that law, it was statutorily established as ''Misty Fjords N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada–United States Border
The border between Canada and the United States is the longest international border in the world. The terrestrial boundary (including boundaries in the Great Lakes, Atlantic, and Pacific coasts) is long. The land border has two sections: Canada's border with the contiguous United States to its south, and with the U.S. state of Alaska to its west. The bi-national International Boundary Commission deals with matters relating to marking and maintaining the boundary, and the International Joint Commission deals with issues concerning boundary waters. The agencies currently responsible for facilitating legal passage through the international boundary are the Canada Border Services Agency (CBSA) and U.S. Customs and Border Protection (CBP). History 18th century The Treaty of Paris of 1783 ended the American Revolutionary War between Great Britain and the United States. In the second article of the Treaty, the parties agreed on all boundaries of the United States, including, but ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Mountain Ranges
This is a list of mountain ranges on Earth and a few other astronomical bodies. First, the highest and longest mountain ranges on Earth are listed, followed by more comprehensive alphabetical lists organized by continent. Ranges in the oceans and on other celestial bodies are listed afterwards. Mountain ranges on planet Earth By size Note 1: A peak included in the "Eastern Pamirs" more often than in the Kunlun Mountains, as Kongur Tagh and the Kunlun range are ''separated'' by the large Yarkand River valley; no valley of such significance separates the Pamirs and Kongur Tagh, just political boundaries. Note 2: Part of Hindu Kush-Himalayas region All of the Asian ranges above have been formed in part over the past 35 to 55 million years by the collision between the Indian Plate and Eurasian Plate. The Indian Plate is still particularly mobile and these mountain ranges continue to rise in elevation every year and this page may need to be updated in a few years; of these th ...
