Denali is the highest mountain peak in North America, with a summit elevation of 20,310 feet above sea level. With a topographic prominence of 20,156 feet and a topographic isolation of 4,629 miles, Denali is the third most prominent and third most isolated peak on Earth, after Mount Everest and Aconcagua. Located in the Alaska Range in the interior of the U. S. state of Alaska, Denali is the centerpiece of Preserve. The Koyukon people who inhabit the area around the mountain have referred to the peak as "Denali" for centuries. In 1896, a gold prospector named it "Mount McKinley" in support of then-presidential candidate William McKinley. In August 2015, following the 1975 lead of the State of Alaska, the United States Department of the Interior announced the change of the official name of the mountain to Denali. In 1903, James Wickersham recorded the first attempt at climbing Denali, unsuccessful. In 1906, Frederick Cook claimed the first ascent, proven to be false; the first verifiable ascent to Denali's summit was achieved on June 7, 1913, by climbers Hudson Stuck, Harry Karstens, Walter Harper, Robert Tatum, who went by the South Summit.
In 1951, Bradford Washburn pioneered the West Buttress route, considered to be the safest and easiest route, therefore the most popular in use. On September 2, 2015, the U. S. Geological Survey announced that the mountain is 20,310 feet high, not 20,320 feet, as measured in 1952 using photogrammetry. Denali is a granitic pluton lifted by tectonic pressure from the subduction of the Pacific Plate beneath the North American Plate; the forces that lifted Denali cause many deep earthquakes in Alaska and the Aleutian Islands. The Pacific Plate is seismically active beneath Denali, a tectonic region, known as the "McKinley cluster". Denali has a summit elevation of 20,310 feet above sea level, making it the highest peak in North America and the northernmost mountain above 6,000 meters elevation in the world. Measured from base to peak at some 18,000 ft, it is among the largest mountains situated above sea level. Denali rises from a sloping plain with elevations from 1,000 to 3,000 ft, for a base-to-peak height of 17,000 to 19,000 ft.
By comparison, Mount Everest rises from the Tibetan Plateau at a much higher base elevation. Base elevations for Everest range from 13,800 ft on the south side to 17,100 ft on the Tibetan Plateau, for a base-to-peak height in the range of 12,000 to 15,300 ft. Denali's base-to-peak height is little more than half the 33,500 ft of the volcano Mauna Kea, which lies under water. Denali has two significant summits: the South Summit is the higher one, while the North Summit has an elevation of 19,470 ft and a prominence of 1,270 ft; the North Summit is sometimes counted as sometimes not. Five large glaciers flow off the slopes of the mountain; the Peters Glacier lies on the northwest side of the massif, while the Muldrow Glacier falls from its northeast slopes. Just to the east of the Muldrow, abutting the eastern side of the massif, is the Traleika Glacier; the Ruth Glacier lies to the southeast of the mountain, the Kahiltna Glacier leads up to the southwest side of the mountain. With a length of 44 mi, the Kahiltna Glacier is the longest glacier in the Alaska Range.
The Koyukon Athabaskans who inhabit the area around the mountain have for centuries referred to the peak as Dinale or Denali. The name is based on a Koyukon word for "high" or "tall". During the Russian ownership of Alaska, the common name for the mountain was Bolshaya Gora, the Russian translation of Denali, it was called Densmore's Mountain in the late 1880s and early 1890s after Frank Densmore, an Alaskan prospector, the first European to reach the base of the mountain. In 1896, a gold prospector named it McKinley as political support for then-presidential candidate William McKinley, who became president the following year; the United States formally recognized the name Mount McKinley after President Wilson signed the Mount McKinley National Park Act of February 26, 1917. In 1965, Lyndon B. Johnson declared the north and south peaks of the mountain the "Churchill Peaks", in honor of British statesman Winston Churchill; the Alaska Board of Geographic Names changed the name of the mountain to Denali in 1975, how it is called locally.
However, a request in 1975 from the Alaska state legislature to the United States Board on Geographic Names to do the same at the federal level was blocked by Ohio congressman Ralph Regula, whose district included McKinley's hometown of Canton. On August 30, 2015, just ahead of a presidential visit to Alaska, the Barack Obama administration announced the name Denali would be restored in line with the Alaska Geographic Board's designation. U. S. Secretary of the Interior Sally Jewell issued the order changing the name to Denali on August 28, 2015, effective immediately. Jewell said the change had been "a long time coming"; the renaming of the mountain received praise from Alaska's senior U. S. senator, Lisa Murkowski, who had introduced legislation to accomplish the name change, but it drew criticism from several politicians from Pres
Mount Whitney is the tallest mountain in California, as well as the highest summit in the contiguous United States and the Sierra Nevada—with an elevation of 14,505 feet. It is in Central California, on the boundary between California's Inyo and Tulare counties, 84.6 miles west-northwest of the lowest point in North America at Badwater Basin in Death Valley National Park at 282 ft below sea level. The west slope of the mountain is in Sequoia National Park and the summit is the southern terminus of the John Muir Trail which runs 211.9 mi from Happy Isles in Yosemite Valley. The east slope is in the Inyo National Forest in Inyo County; the summit of Mount Whitney is on the Great Basin Divide. It lies near many of the highest peaks of the Sierra Nevada; the peak rises above the Owens Valley, sitting 10,778 feet or just over two miles above the town of Lone Pine 15 miles to the east, in the Owens Valley. It rises more on the west side, lying only about 3,000 feet above the John Muir Trail at Guitar Lake.
The mountain is dome-shaped, with its famously jagged ridges extending to the sides. Mount Whitney has an alpine climate and ecology. Few plants grow near the summit: one example is the sky pilot, a cushion plant that grows low to the ground; the only animals are transient, such as the butterfly Parnassius phoebus and the gray-crowned rosy finch. The mountain is the highest point on the Great Basin Divide. Waterways on the west side of the peak flow into Whitney Creek; the Kern River terminates in the Tulare Basin. During wet years, water overflows from the Tulare Basin into the San Joaquin River which flows to the Pacific Ocean. From the east, water from Mount Whitney flows to Lone Pine Creek, which joins the Owens River, which in turn terminates at Owens Lake, an endorheic lake of the Great Basin; the estimated elevation of the summit of Mount Whitney has changed over the years. The technology of elevation measurement has become more refined and, more the vertical coordinate system has changed.
The peak was said to be at 14,494 ft and this is the elevation stamped on the USGS brass benchmark disk on the summit. An older plaque on the summit reads "elevation 14,496.811 feet" but this was estimated using the older vertical datum from 1929. Since the shape of the Earth has been estimated more accurately. Using a new vertical datum established in 1988 the benchmark is now estimated to be at 14,505 ft; the eastern slope of Whitney is far steeper than its western slope because the entire Sierra Nevada is the result of a fault-block, analogous to a cellar door: the door is hinged on the west and is rising on the east. The rise is caused by a normal fault system that runs along the eastern base of the Sierra, below Mount Whitney. Thus, the granite that forms Mount Whitney is the same as the granite that forms the Alabama Hills, thousands of feet lower down; the raising of Whitney is due to the same geological forces that cause the Basin and Range Province: the crust of much of the intermontane west is being stretched.
The granite that forms Mount Whitney is part of the Sierra Nevada batholith. In Cretaceous time, masses of molten rock that originated from subduction rose underneath what is now Whitney and solidified underground to form large expanses of granite. In the last 2 to 10 million years, the Sierra was pushed up which enabled glacial and river erosion to strip the upper layers of rock to reveal the resistant granite that makes up Mount Whitney today. In July 1864, the members of the California Geological Survey named the peak after Josiah Whitney, the State Geologist of California and benefactor of the survey. During the same expedition, geologist Clarence King attempted to climb Whitney from its west side, but stopped just short. In 1871, King returned to climb what he believed to be Whitney, but having taken a different approach, he summited nearby Mount Langley. Upon learning of his mistake in 1873, King completed his own first ascent of Whitney, but did so a month too late to claim the first recorded ascent.
Just a month earlier, on August 18, 1873, Charles Begole, A. H. Johnson, John Lucas, all of nearby Lone Pine, had become the first to reach the highest summit in the contiguous United States; as they climbed the mountain during a fishing trip to nearby Kern Canyon, they called the mountain Fisherman's Peak. In 1881 Samuel Pierpont Langley, founder of the Smithsonian Astrophysical Observatory remained for some time on the summit, making daily observations on the solar heat. Accompanying Langley in 1881 was another party consisting of Judge William B. Wallace of Visalia, W. A. Wright and Reverend Frederick Wales. Wallace wrote in his memoirs that "The Pi Ute Indians called Mt. Whitney "Too-man-i-goo-yah," which means "the old man." They believe that the Great Spirit who presides over the destiny of their people once had his home in that mountain." The spelling Too-man-i-goo-yah is a transliteration from the indigenous Paiute Mono language. Other variations are Tumanguya. In 1891, the United States Geological Survey's Board on Geographic Names decided to recognize the earlier name Mount Whitney.
Despite losing out on their preferred name, residents of Lone Pine financed the first trail to the summit, engineered by Gustave Marsh, completed on July 22, 1904. Just four days the new trail enabled the first recorded death on Whitney. Having hiked the trail, U. S. Bureau of Fisheries employee Byrd Surby was struck and killed by lightning while eating lunch
A gendarme is a pinnacle of rock on a mountain ridge. They are typical of alpine areas. Gendarmes form on the intersection of two ridges due to the lower erosion of glaciers here; the name originates from the French Alps, where they were seen as resembling the gendarmerie police
Canada is a country in the northern part of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering 9.98 million square kilometres, making it the world's second-largest country by total area. Canada's southern border with the United States is the world's longest bi-national land border, its capital is Ottawa, its three largest metropolitan areas are Toronto and Vancouver. As a whole, Canada is sparsely populated, the majority of its land area being dominated by forest and tundra, its population is urbanized, with over 80 percent of its inhabitants concentrated in large and medium-sized cities, many near the southern border. Canada's climate varies across its vast area, ranging from arctic weather in the north, to hot summers in the southern regions, with four distinct seasons. Various indigenous peoples have inhabited what is now Canada for thousands of years prior to European colonization. Beginning in the 16th century and French expeditions explored, settled, along the Atlantic coast.
As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces; this began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom. This widening autonomy was highlighted by the Statute of Westminster of 1931 and culminated in the Canada Act of 1982, which severed the vestiges of legal dependence on the British parliament. Canada is a parliamentary democracy and a constitutional monarchy in the Westminster tradition, with Elizabeth II as its queen and a prime minister who serves as the chair of the federal cabinet and head of government; the country is a realm within the Commonwealth of Nations, a member of the Francophonie and bilingual at the federal level. It ranks among the highest in international measurements of government transparency, civil liberties, quality of life, economic freedom, education.
It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many other countries. Canada's long and complex relationship with the United States has had a significant impact on its economy and culture. A developed country, Canada has the sixteenth-highest nominal per capita income globally as well as the twelfth-highest ranking in the Human Development Index, its advanced economy is the tenth-largest in the world, relying chiefly upon its abundant natural resources and well-developed international trade networks. Canada is part of several major international and intergovernmental institutions or groupings including the United Nations, the North Atlantic Treaty Organization, the G7, the Group of Ten, the G20, the North American Free Trade Agreement and the Asia-Pacific Economic Cooperation forum. While a variety of theories have been postulated for the etymological origins of Canada, the name is now accepted as coming from the St. Lawrence Iroquoian word kanata, meaning "village" or "settlement".
In 1535, indigenous inhabitants of the present-day Quebec City region used the word to direct French explorer Jacques Cartier to the village of Stadacona. Cartier used the word Canada to refer not only to that particular village but to the entire area subject to Donnacona. From the 16th to the early 18th century "Canada" referred to the part of New France that lay along the Saint Lawrence River. In 1791, the area became two British colonies called Upper Canada and Lower Canada collectively named the Canadas. Upon Confederation in 1867, Canada was adopted as the legal name for the new country at the London Conference, the word Dominion was conferred as the country's title. By the 1950s, the term Dominion of Canada was no longer used by the United Kingdom, which considered Canada a "Realm of the Commonwealth"; the government of Louis St. Laurent ended the practice of using'Dominion' in the Statutes of Canada in 1951. In 1982, the passage of the Canada Act, bringing the Constitution of Canada under Canadian control, referred only to Canada, that year the name of the national holiday was changed from Dominion Day to Canada Day.
The term Dominion was used to distinguish the federal government from the provinces, though after the Second World War the term federal had replaced dominion. Indigenous peoples in present-day Canada include the First Nations, Métis, the last being a mixed-blood people who originated in the mid-17th century when First Nations and Inuit people married European settlers; the term "Aboriginal" as a collective noun is a specific term of art used in some legal documents, including the Constitution Act 1982. The first inhabitants of North America are hypothesized to have migrated from Siberia by way of the Bering land bridge and arrived at least 14,000 years ago; the Paleo-Indian archeological sites at Old Crow Flats and Bluefish Caves are two of the oldest sites of human habitation in Canada. The characteristics of Canadian indigenous societies included permanent settlements, complex societal hierarchies, trading networks; some of these cultures had collapsed by the time European explorers arrived in the late 15th and early 16th centuries and have only been discovered through archeological investigations.
The indigenous population at the time of the first European settlements is estimated to have been between 200,000
A mountain is a large landform that rises above the surrounding land in a limited area in the form of a peak. A mountain is steeper than a hill. Mountains are formed through tectonic forces or volcanism; these forces can locally raise the surface of the earth. Mountains erode through the action of rivers, weather conditions, glaciers. A few mountains are isolated summits. High elevations on mountains produce colder climates than at sea level; these colder climates affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, such as mountain climbing; the highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m. There is no universally accepted definition of a mountain.
Elevation, relief, steepness and continuity have been used as criteria for defining a mountain. In the Oxford English Dictionary a mountain is defined as "a natural elevation of the earth surface rising more or less abruptly from the surrounding level and attaining an altitude which to the adjacent elevation, is impressive or notable."Whether a landform is called a mountain may depend on local usage. Mount Scott outside Lawton, Oklahoma, USA, is only 251 m from its base to its highest point. Whittow's Dictionary of Physical Geography states "Some authorities regard eminences above 600 metres as mountains, those below being referred to as hills." In the United Kingdom and the Republic of Ireland, a mountain is defined as any summit at least 2,000 feet high, whilst the official UK government's definition of a mountain, for the purposes of access, is a summit of 600 metres or higher. In addition, some definitions include a topographical prominence requirement 100 or 500 feet. At one time the U.
S. Board on Geographic Names defined a mountain as being 1,000 feet or taller, but has abandoned the definition since the 1970s. Any similar landform lower. However, the United States Geological Survey concludes that these terms do not have technical definitions in the US; the UN Environmental Programme's definition of "mountainous environment" includes any of the following: Elevation of at least 2,500 m. Using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, 14% of Africa; as a whole, 24% of the Earth's land mass is mountainous. There are three main types of mountains: volcanic and block. All three types are formed from plate tectonics: when portions of the Earth's crust move and dive. Compressional forces, isostatic uplift and intrusion of igneous matter forces surface rock upward, creating a landform higher than the surrounding features; the height of the feature makes it either a hill or, if steeper, a mountain. Major mountains tend to occur in long linear arcs, indicating tectonic plate boundaries and activity.
Volcanoes are formed when a plate is pushed at a mid-ocean ridge or hotspot. At a depth of around 100 km, melting occurs in rock above the slab, forms magma that reaches the surface; when the magma reaches the surface, it builds a volcanic mountain, such as a shield volcano or a stratovolcano. Examples of volcanoes include Mount Pinatubo in the Philippines; the magma does not have to reach the surface in order to create a mountain: magma that solidifies below ground can still form dome mountains, such as Navajo Mountain in the US. Fold mountains occur when two plates collide: shortening occurs along thrust faults and the crust is overthickened. Since the less dense continental crust "floats" on the denser mantle rocks beneath, the weight of any crustal material forced upward to form hills, plateaus or mountains must be balanced by the buoyancy force of a much greater volume forced downward into the mantle, thus the continental crust is much thicker under mountains, compared to lower lying areas.
Rock can fold either asymmetrically. The upfolds are anticlines and the downfolds are synclines: in asymmetric folding there may be recumbent and overturned folds; the Balkan Mountains and the Jura Mountains are examples of fold mountains. Block mountains are caused by faults in the crust: a plane; when rocks on one side of a fault rise relative to the other, it can form a mountain. The uplifted blocks are block horsts; the intervening dropped blocks are termed graben: these can be small or form extensive rift valley systems. This form of landscape can be seen in East Africa, the Vosges, the Basin and Range Province of Western North America and the Rhine valley; these areas occur when the regional stress is extensional and the crust is thinned. During and following uplift, mountains are subjected to the agents of erosion which wear the uplifted area down. Erosion causes the surface of mountains to be younger than the rocks that form the mountains themselves. Glacial processes produce characteristic landforms, such as pyramidal peaks, knife-edge arêtes, bowl-shaped cirques that can contai
Mount Fairweather, is the highest mountain in the Canadian province of British Columbia, with an elevation of 4,671 metres. It is located 20 km east of the Pacific Ocean on the border of Alaska, United States and western British Columbia, Canada. Most of the mountain lies within Glacier Bay National Park and Preserve in the City and Borough of Yakutat, though the summit borders Tatshenshini-Alsek Provincial Park, British Columbia, it is designated as Boundary Peak 164 or as US/Canada Boundary Point #164. The mountain was named on May 3, 1778 by Captain James Cook for the unusually good weather encountered at the time; the name has been translated into many languages. It was called "Mt. Beautemps" by La Perouse, "Mte. Buen-tiempo" by Galiano, "Gor-Khoroshy-pogody" on Russian Hydrographic Dept. Chart 1378 in 1847, "G Fayerveder" by Captain Tebenkov, Imperial Russian Navy, it was called "Schönwetterberg" by Constantin Grewingk in 1850 and "Schönwetter Berg" by Justus Perthes in 1882. Fairweather was first climbed in 1931 by Allen Carpé and Terris Moore.
Mount Fairweather is located right above Glacier Bay in the Fairweather Range of the Saint Elias Mountains. Mount Fairweather marks the northwest extremity of the Alaska Panhandle. Like many peaks in the St. Elias Mountains, Mount Fairweather has great vertical relief due to its dramatic rise from Glacier Bay. However, due to poor weather in the area, this effect is obscured with the clouds which hides the summit from view. Known in the Tlingit language as Tsalxhaan, it is said this mountain and Yaas'éit'aa Shaa were next to each other but had an argument and separated, their children, the mountains in between the two peaks, are called Tsalxhaan Yatx'i Despite its name, Mount Fairweather has harsh weather conditions. It receives over 100 inches of precipitation each year and sees temperatures of around -50 °F. 1926 Allen Carpe, Andy Taylor and W. S. Ladd reached 2,890 m on the West Ridge, but were forced back due to a steep notch in the ridge that made ferrying supplies difficult. 1930 Bradford Washburn made an attempt on the West Ridge but traveling conditions forced a retreat at 2,040 metres.
1931 Allen Carpe and Terris Moore summited via the Southeast Ridge on June 8, 1931 1958 Paddy Sherman and 7 other Canadians reached the summit via the SE Ridge on June 26, 1958. 1968 West Ridge, Loren Adkins, Walter Gove, Paul Myhre, John Neal and Kent Stokes - summit reached June 12, 1968 1973 Southwest Ridge, Peter Metcalf, Henry Florschutz, Toby O'Brien and Lincoln Stoller. Summit reached on July 10, 1973. After failing to reach the summit in 1926 due to terrain difficulty on their chosen route, Allen Carpe, W. S. Ladd, Andy Taylor returned in 1931 along with a new member Terry Moore. In early April the group began their approach by boat but stormy weather delayed them rounding Cape Fairweather until April 17, they unloaded their supplies on the beach. Backtracking 21 kilometres along the coast, they made their way to the Fairweather Glacier. From base camp in a spot they called Paradise Valley, they decided to attempt the mountain from the south rather than via the west ridge. Due to deep snow, they realized that skis and snowshoes would be of great help so Carpe and Moore made the 80 km round trip to fetch them from Lituya Bay.
They ascended the glacier from base setup camp at 1,520 m on the mountain's south face. On May 25, they established high camp at 2,740 m after making significant progress up a ridge on a rare day of good weather. However, the weather turned and they were forced to descend after an overnight coating of snow. After waiting out the snowstorm for six days at lower camp, they made their way back up to high camp on June 2, they left for the summit at 1:30 am on June 3 and having reached the southeast shoulder by mid-morning, they were feeling so confident that they left the willow wands behind. However, higher altitude and the weeks of hard effort slowed their progress and the weather changed. By 1 pm not far from the summit, they decided to retreat and had to descend without the wands to guide them, they managed to reach the tents by 4 pm. Ladd and Taylor volunteered to descend due to dwindling supplies at high camp with the hope that Carpe and Moore would be able to make another attempt in good weather.
The storm raged for four days before it cleared in the evening on June 7. At 10 pm, Carpe and Moore set out for the summit and with no further difficulties made it to the top.

In mountaineering, a first ascent 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 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 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; the details of the first ascents of many prominent mountains are scanty or unknown. Today, first ascents are carefully recorded and mentioned in guidebooks. Overwhelmingly, the idea of a "first ascent" is a modern one in places such as Africa and the Americas with a history of colonialism. There may be little or no physical evidence or documentation about the climbing activities of indigenous peoples living near the mountain.
For example, the volcano Llullaillaco on the border of Argentina and Chile is known to have been climbed in the prehistoric period due to the presence of Incan artifacts at the summit, yet credit for the first recorded ascent is given to Chilean climbers Bión González and Juan Harseim, who summited in 1952. The term is used when referring to ascents made using a specific technique or taking a specific route, such as via the North Face, without ropes or without oxygen. In rock climbing, some of the earlier first ascents for difficult routes, involved a mix of free and aid climbing; as a result, purist free climbers have developed the designation first free ascent to acknowledge ascents intentionally made more challenging by using equipment for protection only. Second ascents are noteworthy in climbing circles involving improving on a pioneering route through lessons learned from it, experience which may span from technical improvements to having a better understanding of how much gear and provisions to take.
Some other "first ascents" could be recorded for particular routes. One is the First Winter Ascent, which is, as the name suggests, the first ascent made during winter season; this is most important where the climate of winter is a factor in increasing the difficulty grade of the route. In the Northern Hemisphere conventional winter ascents are made between December 21 and March 21 and are not related to the conditions. In the Himalayan area, although Nepal and China's winter season permits start on December 1, the conventional winter ascents begin on December 21. Another is the First Solo Ascent, the first ascent made by a single climber; this is most important on high-level rock climbing, when the climber has to provide his own security or when climbing without any protection at all. Another type of ascent known as FFA is the first female ascent. While not considered as important, this designation remains significant on some difficult, limit-pushing climbs, where the first female ascent may not happen until well after the FA, due to possible difficulties encountered by female physicality.
The term last ascent has been used to refer to an ascent of a mountain or face that has subsequently changed to such an extent – because of rockfall – that the route no longer exists. It can be used facetiously to refer to a climb, so unpleasant or unaesthetic that no one would willingly repeat the first ascent party's ordeal.
