Owens Lake is a mostly dry lake in the Owens Valley on the eastern side of the Sierra Nevada in Inyo County, California. It is about 5 miles south of Lone Pine, today, some of the flow of the river has been restored, and the lake now contains some water. Nevertheless, as of 2013, it is the largest single source of dust pollution in the United States, Owens Lake was given that name by the explorer John C. Fremont, in honor of one of his guides, Richard Owens, before the diversion of the Owens River, Owens Lake was up to 12 miles long and 8 miles wide, covering an area of up to 108 square miles. In the last few hundred years the lake had a depth of 23 to 50 feet. In 1905, the water was thought to be “excessively saline. ”It is thought that in the late Pleistocene about 11-12,000 years ago Owens Lake was even larger, covering nearly 200 square miles. Starting in 1913, the river and streams that fed Owens Lake were diverted by Los Angeles Department of Water and Power into the Los Angeles Aqueduct, as the lake dried, soda processing at Keeler switched from relatively cheap chemical methods to more expensive physical ones.
The Natural Soda Products Company sued the city of Los Angeles, a fire destroyed this plant shortly after it was built but the company rebuilt it on the dry lakebed in the 1920s. During the unusually wet winter of 1937, LADWP diverted water from the aqueduct into the lakebed, because of this the courts ordered the city to pay $154,000. After an unsuccessful attempt to the state supreme court in 1941, LADWP built the Long Valley Dam. The lake is currently a salt flat whose surface is made of a mixture of clay, and a variety of minerals including halite, mirabilite, thenardite. In wet years, these form a chemical soup in the form of a small brine pond within the dry lake. When conditions are right, bright pink halophilic archaea spread across the salty lakebed, also, on especially hot summer days when ground temperatures exceed 150° F, water is driven out of the hydrates on the lakebed creating a muddy brine. More commonly, periodic winds stir up noxious alkali dust storms that carry away as much as four million tons of dust from the each year.
The dust includes carcinogens such as cadmium and arsenic, the LADWP and the California State Lands Commission own most of the Owens Lake bed, though a few small parcels along the historic western shoreline are privately owned. In 2004, the California Department of Fish and Wildlife acquired a 218-acre parcel at the foot of Owens Lake, designated the Cartago Wildlife Area in 2007, it is one of the few remaining spring and wetland areas on the shore of Owens Lake. CDFW is using mitigation funds from CalTrans to enhance habitat, as part of an air quality mitigation settlement, LADWP is currently shallow flooding 27 square miles of the salt pan to try to help minimize alkali dust storms and further adverse health effects. There is about 3.5 square miles of managed vegetation being used as a dust control measure, the vegetation consists of saltgrass, which is a native perennial grass highly tolerant of the salt and boron levels in the lake sediments
Pacific Crest Trail
The Pacific Crest Trail is 2,659 mi long and ranges in elevation from just above sea level at the Oregon–Washington border to 13,153 feet at Forester Pass in the Sierra Nevada. The route passes through 25 national forests and 7 national parks and its midpoint is near Chester, where the Sierra and Cascade mountain ranges meet. It was designated a National Scenic Trail in 1968, although it was not officially completed until 1993, the PCT was conceived by Clinton Churchill Clarke in 1932. It received official status under the National Trails System Act of 1968 and it is the westernmost and second longest component of the Triple Crown of Hiking and is part of the 6, 875-mile Great Western Loop. The route is mostly through National Forest and protected wilderness, the trail avoids civilization and covers scenic and pristine mountainous terrain with few roads. A parallel route for bicycles, the Pacific Crest Bicycle Trail is a 2, the PCT and PCBT cross in about 27 places along their routes. The Pacific Crest Trail was first proposed by Clinton C, Clarke, as a trail running from Mexico to Canada along the crest of the mountains in California and Washington.
The original proposal was to link the John Muir Trail, the Tahoe-Yosemite Trail, the Skyline Trail, the Pacific Crest Trail System Conference was formed by Clarke to both plan the trail and to lobby the federal government to protect the trail. The conference was founded by Clarke, the Boy Scouts, the YMCA, from 1935 through 1938, YMCA groups explored the 2000 miles of potential trail and planned a route, which has been closely followed by the modern PCT route. In 1968, President Lyndon B. Johnson defined the PCT, the PCT was constructed through cooperation between the federal government and volunteers organized by the Pacific Crest Trail Association. In 1993, the PCT was officially declared finished, thru hiking is a term used in referring to hikers who complete long-distance trails from end to end in a single trip. The Pacific Crest Trail, Appalachian Trail, and Continental Divide Trail were the first three long-distance trails in the U. S, successfully thru-hiking all of these three trails is known as the Triple Crown of Hiking.
Thru-hiking is a commitment, usually taking between four and six months, that requires thorough preparation and dedication. The Pacific Crest Trail Association estimates that it takes most hikers between six and eight months to plan their trip, while most hikers travel from the Southern Terminus at the Mexico–US border northward to Manning Park, British Columbia, some hikers prefer a southbound route. In a normal year, northbound hikes are most practical due to snow. If snowpack in the Sierra Nevada is high in early June and low in the Northern Cascades, however, it is not currently possible to legally enter the United States from Canada by using the Pacific Crest Trail. Hikers have to determine their resupply points, resupply points are towns or post offices where hikers replenish food and other supplies such as cooking fuel. Hikers can ship packages to themselves at the U. S, post Offices along the trail, resupply at general and grocery stores along the trail, or any combination of the two
Tulare County, California
Tulare County is a county in the U. S. state of California. As of the 2010 census, the population was 442,179, the county is named for Tulare Lake, once the largest freshwater lake west of the Great Lakes. Drained for agricultural development, the site is now in Kings County, Tulare County comprises the Visalia-Porterville, CA Metropolitan Statistical Area. The county is located south of Fresno, spanning from the San Joaquin Valley east to the Sierra Nevada. Sequoia National Park is located in the county, as are part of Kings Canyon National Park, in its northeast corner, as of the 2010 census, the population was 442,179, up from 368,021 at the 2000 census. The land was occupied for thousands of years by varying cultures of indigenous peoples, beginning in the eighteenth century, Spain established missions to colonize California and convert the American Indians to Christianity. Comandante Pedro Fages, while hunting for deserters in the Central Valley in 1772, discovered a lake surrounded by marshes and filled with rushes.
It is from this lake that the county derives its name, the root of the name Tulare is found in the Nahuatl word tullin, designating cattail or similar reeds. After Mexico achieved independence, it continued to rule California, after the Mexican Cession and the Treaty of Guadalupe Hidalgo in 1848, the area became part of the United States. Tulare County was soon formed from parts of Mariposa County only 4 years in 1852, there were two early attempts to split off a new Buena Vista County in 1855, and Coso County in 1864, but both failed. Parts of the territory were given to Fresno County in 1856, to Kern County and to Inyo County in 1866. The infectious disease Tularemia caused by the bacterium Francisella tularensis is named after Tulare County, in 1908 Colonel Allen Allensworth and associates founded Allensworth as a black farming community. They intended to develop a place where African Americans could thrive free of white discrimination and it was the only community in California founded and governed by African Americans.
While its first years were successful, the community encountered environmental problems from dropping water tables which eventually caused it to fail. Today the historic area is preserved as the Colonel Allensworth State Historic Park, which is listed on the National Register of Historic Places. According to the U. S. Census Bureau, the county has an area of 4,839 square miles. It was established in 1890 as the second U. S. national park, the park is south of and contiguous with Kings Canyon National Park, the two are administered by the National Park Service as one unit, called Sequoia and Kings Canyon National Parks. State Route 43 State Route 63 State Route 65 State Route 99 State Route 180 State Route 190 State Route 198 Tulare County Transit provides a bus service linking the population centers
Rock climbing is an activity in which participants climb up, down or across natural rock formations or artificial rock walls. The goal is to reach the summit of a formation or the endpoint of a usually pre-defined route without falling. Due to the length and extended endurance required and because accidents are likely to happen on descent than ascent. It is very rare for a climber to downclimb, especially on the larger multiple pitches, professional Rock climbing competitions have the objectives of either completing the route in the quickest possible time or attaining the farthest point on an increasingly difficult route. Scrambling, another activity involving the scaling of hills and similar formations, is similar to rock climbing, rock climbing is generally differentiated by its sustained use of hands to support the climbers weight as well as to provide balance. Rock climbing is a physically and mentally demanding sport, one that often tests a climbers strength, agility and it can be a dangerous activity and knowledge of proper climbing techniques and usage of specialized climbing equipment is crucial for the safe completion of routes.
Because of the range and variety of rock formations around the world. Paintings dating from 200 BC show Chinese men rock climbing China woop woop, in early America, the cliff-dwelling Anasazi in the 12th century were thought to be excellent climbers. Early European climbers used rock climbing techniques as a required to reach the summit in their mountaineering exploits. In the 1880s, European rock climbing become an independent pursuit outside of mountain climbing, Rock climbing evolved gradually from an alpine necessity to a distinct athletic activity. However, climbing techniques and ethical considerations have evolved steadily, free climbing, climbing using holds made entirely of natural rock while using gear solely for protection and not for upward movement, is the most popular form of the sport. Free climbing has since divided into several sub-styles of climbing dependent on belay configuration. Over time, grading systems have created in order to compare more accurately the relative difficulties of the rock climbs.
In How to Rock Climb, John Long notes that for moderately skilled climbers simply getting to the top of a route is not enough, in rock climbing, style refers to the method of ascending the cliff. There are three styles of climbing, on-sight and redpoint. To on-sight a route is to ascend the wall without aid or any foreknowledge and it is considered the way to climb with the most style. Flashing is similar to on-sighting, except that the climber has previous information about the route including talking about the beta with other climbers, redpointing means to make a free ascent of the route after having first tried it. Free climbing is typically divided into styles that differ from one another depending on the choice of equipment used
Fishing is the activity of trying to catch fish. Fish are normally caught in the wild, techniques for catching fish include hand gathering, netting and trapping. Fishing may include catching aquatic animals other than fish, such as molluscs, crustaceans, the term is not normally applied to catching farmed fish, or to aquatic mammals, such as whales where the term whaling is more appropriate. According to United Nations FAO statistics, the number of commercial fishermen. Fisheries and aquaculture provide direct and indirect employment to over 500 million people in developing countries, in 2005, the worldwide per capita consumption of fish captured from wild fisheries was 14.4 kilograms, with an additional 7.4 kilograms harvested from fish farms. In addition to providing food, modern fishing is a recreational pastime, Fishing is an ancient practice that dates back to at least the beginning of the Upper Paleolithic period about 40,000 years ago. Isotopic analysis of the remains of Tianyuan man, a 40.
Archaeology features such as middens, discarded fish bones, and cave paintings show that sea foods were important for survival. During this period, most people lived a lifestyle and were, of necessity. However, where there are examples of permanent settlements such as those at Lepenski Vir. The British dogger was a type of sailing trawler from the 17th century. The Brixham trawler that evolved there was of a build and had a tall gaff rig. They were sufficiently robust to be able to tow large trawls in deep water, the great trawling fleet that built up at Brixham, earned the village the title of Mother of Deep-Sea Fisheries. The small village of Grimsby grew to become the largest fishing port in the world by the mid 19th century, an Act of Parliament was first obtained in 1796, which authorised the construction of new quays and dredging of the Haven to make it deeper. It was only in the 1846, with the expansion in the fishing industry. The foundation stone for the Royal Dock was laid by Albert the Prince consort in 1849, the dock covered 25 acres and was formally opened by Queen Victoria in 1854 as the first modern fishing port.
The elegant Brixham trawler spread across the world, influencing fishing fleets everywhere, by the end of the 19th century, there were over 3,000 fishing trawlers in commission in Britain, with almost 1,000 at Grimsby. These trawlers were sold to fishermen around Europe, including from the Netherlands, twelve trawlers went on to form the nucleus of the German fishing fleet
Skiing is a mode of transport, recreational activity and competitive winter sport in which the participant uses skis to glide on snow. Many types of skiing events are recognized by the International Olympic Committee. Skiing has a history of almost five millennia, although modern skiing has evolved from beginnings in Scandinavia, it may have been practiced as early as 600 BC in what is now China. The word ski is one of a handful of words Norway has exported to the international community and it comes from the Old Norse word skíð which means split piece of wood or firewood. Asymmetrical skis were used at least in northern Finland and Sweden until the late 19th century, on one leg the skier wore a long straight non-arching ski for sliding, and on the other a shorter ski for kicking. Early skiers used one long pole or spear, the first depiction of a skier with two ski poles dates to 1741. Until the mid-19th century skiing was primarily used for transport, and since has become a recreation, military ski races were held in Norway during the 18th century, and ski warfare was studied in the late 18th century.
As equipment evolved and ski lifts were developed skiing evolved into two main genres during the late 19th and early 20th century and Nordic, called downhill skiing, alpine skiing typically takes place on a piste at a ski resort. It is characterized by fixed-heel bindings that attach at both the toe and the heel of the skiers boot, because alpine equipment is somewhat difficult to walk in, ski lifts, including chairlifts, bring skiers up the slope. Backcountry skiing can be accessed by helicopter, hiking, facilities at resorts can include night skiing, après-ski, and glade skiing under the supervision of the ski patrol and the ski school. Alpine skiing branched off from the older Nordic skiing around the 1920s, Alpine equipment specialized to where it can only be used with the help of lifts. The Nordic disciplines include cross-country skiing and ski jumping, which share in common the use of binding that attach at the toes of the skiers boots, cross-country skiing may be practiced on groomed trails or in undeveloped backcountry areas.
Ski jumping skiing is practiced at certain areas that are deemed for ski jumping only, Telemark skiing is a ski turning technique and FIS-sanctioned discipline. It is named after the Telemark region of Norway, using equipment similar to nordic skiing, the ski bindings having the ski boot attached only at the toe. This allows the skier to raise his/her heel throughout the turn, the following disciplines are sanctioned by the FIS and USSA. Many have their own cups and are in the Winter Olympic Games. Cross-country, The sport encompasses a variety of formats for cross-country skiing races over courses of varying lengths, such races occur over homologated, groomed courses designed to support classic and free-style events, where the skiers may employ skate skiing. Alpine skiing discliplines include combined, slalom, giant slalom, Super-G, one run of each even like one run of Super-G and one run of Slalom skiing this is called a Super Combined
Sierra Nevada (U.S.)
The Sierra Nevada is a mountain range in the Western United States, between the Central Valley of California and the Basin and Range Province. The vast majority of the lies in the state of California. The Sierra runs 400 miles north-to-south, and is approximately 70 miles across east-to-west, the Sierra is home to three national parks, twenty wilderness areas, and two national monuments. These areas include Yosemite and Kings Canyon National Parks, the character of the range is shaped by its geology and ecology. More than one hundred years ago during the Nevadan orogeny. The range started to uplift four M. A. ago, the uplift caused a wide range of elevations and climates in the Sierra Nevada, which are reflected by the presence of five life zones. Uplift continues due to faulting caused by forces, creating spectacular fault block escarpments along the eastern edge of the southern Sierra. The Sierra Nevada has a significant history, the California Gold Rush occurred in the western foothills from 1848 through 1855.
Due to inaccessibility, the range was not fully explored until 1912, the Sierra Nevada lies in Central and Eastern California, with a very small but historically important spur extending into Nevada. West-to-east, the Sierra Nevadas elevation increases gradually from 1,000 feet in the Central Valley to an height of about 10,500 feet at its crest only 50–75 miles to the east. The east slope forms the steep Sierra Escarpment, unlike its surroundings, the range receives a substantial amount of snowfall and precipitation due to orographic lift. The Sierra Nevada stretches from the Susan River and Fredonyer Pass in the north to Tehachapi Pass in the south and it is bounded on the west by Californias Central Valley and on the east by the Basin and Range Province. The geographical boundary between the Sierra and the Cascades is virtually indistinguishable, with the Fredonyer Pass designation being traditional, physiographically, the Sierra is a section of the Cascade-Sierra Mountains province, which in turn is part of the larger Pacific Mountain System physiographic division.
The range is drained on its western slope by the Central Valley watershed, the northern third of the western Sierra is part of the Sacramento River watershed, and the middle third is drained by the San Joaquin River. The eastern slope watershed of the Sierra is much narrower, its rivers flow out into the endorheic Great Basin of eastern California and western Nevada. Although none of the eastern rivers reach the sea, many of the streams from Mono Lake southwards are diverted into the Los Angeles Aqueduct which provides water to Southern California, the height of the mountains in the Sierra Nevada increases gradually from north to south. Between Fredonyer Pass and Lake Tahoe, the range from 5,000 feet to more than 9,000 feet. The crest near Lake Tahoe is roughly 9,000 feet high, farther south, the highest peak in Yosemite National Park is Mount Lyell
United States Congress
The United States Congress is the bicameral legislature of the federal government of the United States consisting of two chambers, the Senate and the House of Representatives. The Congress meets in the Capitol in Washington, D. C, both senators and representatives are chosen through direct election, though vacancies in the Senate may be filled by a gubernatorial appointment. Members are usually affiliated to the Republican Party or to the Democratic Party, Congress has 535 voting members,435 Representatives and 100 Senators. The House of Representatives has six non-voting members in addition to its 435 voting members and these members can, sit on congressional committees and introduce legislation. Puerto Rico, American Samoa, the Northern Mariana Islands, the members of the House of Representatives serve two-year terms representing the people of a single constituency, known as a district. Congressional districts are apportioned to states by using the United States Census results. Each state, regardless of population or size, has two senators, there are 100 senators representing the 50 states.
Each senator is elected at-large in their state for a term, with terms staggered. The House and Senate are equal partners in the legislative process—legislation cannot be enacted without the consent of both chambers, the Constitution grants each chamber some unique powers. The Senate ratifies treaties and approves presidential appointments while the House initiates revenue-raising bills, the House initiates impeachment cases, while the Senate decides impeachment cases. A two-thirds vote of the Senate is required before a person can be forcibly removed from office. The term Congress can refer to a meeting of the legislature. A Congress covers two years, the current one, the 115th Congress, began on January 3,2017, the Congress starts and ends on the third day of January of every odd-numbered year. Members of the Senate are referred to as senators, members of the House of Representatives are referred to as representatives, congressmen, or congresswomen. One analyst argues that it is not a solely reactive institution but has played a role in shaping government policy and is extraordinarily sensitive to public pressure.
Several academics described Congress, Congress reflects us in all our strengths, Congress is the governments most representative body. Congress is essentially charged with reconciling our many points of view on the public policy issues of the day. —Smith and Wielen Congress is constantly changing and is constantly in flux, most incumbents seek re-election, and their historical likelihood of winning subsequent elections exceeds 90 percent
United States Forest Service
The United States Forest Service is an agency of the U. S. Department of Agriculture that administers the nations 154 national forests and 20 national grasslands, which encompass 193 million acres. Major divisions of the include the National Forest System and Private Forestry, Business Operations. Managing approximately 25% of federal lands, it is the major national land agency that is outside the U. S. Department of the Interior. The concept of the National Forests was born from Theodore Roosevelt’s conservation group and Crockett Club, in 1876, Congress created the office of Special Agent in the Department of Agriculture to assess the quality and conditions of forests in the United States. Hough was appointed the head of the office, in 1881, the office was expanded into the newly formed Division of Forestry. The Forest Reserve Act of 1891 authorized withdrawing land from the domain as forest reserves. In 1901, the Division of Forestry was renamed the Bureau of Forestry, gifford Pinchot was the first United States Chief Forester in the Presidency of Theodore Roosevelt.
As of 2009, the Forest Service has a budget authority of $5.5 billion. The Forest Service employs 34,250 employees in 750 locations, including 10,050 firefighters,737 law enforcement personnel, and 500 scientists. The mission of the Forest Service is To sustain the health and its motto is Caring for the land and serving people. As the lead agency in natural resource conservation, the US Forest Service provides leadership in the protection and use of the nations forest, rangeland. The agencys ecosystem approach to management integrates ecological and social factors to maintain and enhance the quality of the environment to meet current, the everyday work of the Forest Service balances resource extraction, resource protection, and providing recreation.5 billion trees per year. Further, the Forest Service fought fires on 2,996,000 acres of land in 2007, the Forest Service organization includes ranger districts, national forests, research stations and research work units and the Northeastern Area Office for State and Private Forestry.
Each level has responsibility for a variety of functions, the Chief of the Forest Service is a career federal employee who oversees the entire agency. The Chief reports to the Under Secretary for Natural Resources and Environment in the U. S. Department of Agriculture, there are five deputy chiefs for the following areas, National Forest System and Private Forestry and Development, Business Operations, and Finance. The Forest Service Research and Development deputy area includes five stations, the Forest Products Laboratory. Station directors, like regional foresters, report to the Chief, Research stations include Northern, Pacific Northwest, Pacific Southwest, Rocky Mountain, and Southern. There are 92 research work units located at 67 sites throughout the United States, there are 80 Experimental Forests and Ranges that have been established progressively since 1908, many sites are more than 50 years old
Hiking is the preferred term, in Canada and the United States, for a long, vigorous walk, usually on trails, in the countryside, while the word walking is used for shorter, particularly urban walks. On the other hand, in the United Kingdom, and the Republic of Ireland, the word hiking is often used in the UK, along with rambling and fell walking. The term bushwalking is endemic to Australia, having been adopted by the Sydney Bush Walkers club in 1927, in New Zealand a long, vigorous walk or hike is called tramping. It is an activity with numerous hiking organizations worldwide. In the United States, the Republic of Ireland, a day hike refers to a hike that can be completed in a single day. However, in the United Kingdom, the walking is used, as well as rambling. In Northern England, Including the Lake District and Yorkshire Dales, fellwalking describes hill or mountain walks, hiking sometimes involves bushwhacking and is sometimes referred to as such. This specifically refers to walking through dense forest, undergrowth, or bushes.
In extreme cases of bushwhacking, where the vegetation is so dense that human passage is impeded, the Australian term bushwalking refers to both on and off-trail hiking. Common terms for hiking used by New Zealanders are tramping, walking or bushwalking, trekking is the preferred word used to describe multi-day hiking in the mountainous regions of India, Nepal, North America, South America, Iran and in the highlands of East Africa. Hiking a long-distance trail from end-to-end is referred to as trekking, in North America, multi-day hikes, usually with camping, are referred to as backpacking. The idea of taking a walk in the countryside for pleasure developed in the 18th-century, in earlier times walking generally indicated poverty and was associated with vagrancy. Thomas West, an English priest, popularized the idea of walking for pleasure in his guide to the Lake District of 1778. To this end he included various stations or viewpoints around the lakes, published in 1778 the book was a major success.
Another famous early exponent of walking for pleasure, was the English poet William Wordsworth, in 1790 he embarked on an extended tour of France and Germany, a journey subsequently recorded in his long autobiographical poem The Prelude. His famous poem Tintern Abbey was inspired by a visit to the Wye Valley made during a tour of Wales in 1798 with his sister Dorothy Wordsworth. Wordsworths friend Coleridge was another keen walker and in the autumn of 1799, he and Wordsworth undertook a three weeks tour of the Lake District. John Keats, who belonged to the generation of Romantic poets began, in June 1818, a walking tour of Scotland, Ireland
Death Valley National Park
Death Valley National Park is a national park in the United States. Straddling the border of California and Nevada, located east of the Sierra Nevada, the park protects the northwest corner of the Mojave Desert and contains a diverse desert environment of salt-flats, sand dunes, valleys and mountains. It is the largest national park in the lower 48 states and has declared an International Biosphere Reserve. Approximately 91% of the park is a wilderness area. It is the hottest and lowest of the parks in the United States. The second-lowest point in the Western Hemisphere is in Badwater Basin, the park is home to many species of plants and animals that have adapted to this harsh desert environment. Some examples include creosote bush, bighorn sheep and the Death Valley pupfish, several short-lived boom towns sprang up during the late 19th and early 20th centuries to mine gold and silver. The only long-term profitable ore to be mined was borax, which was transported out of the valley with twenty-mule teams, the valley became the subject of books, radio programs, television series, and movies.
Tourism blossomed in the 1920s, when resorts were built around Stovepipe Wells, Death Valley National Monument was declared in 1933 and the park was substantially expanded and became a national park in 1994. The natural environment of the area has been shaped largely by its geology, the valley itself is actually a graben. The oldest rocks are metamorphosed and at least 1.7 billion years old. Ancient, shallow seas deposited marine sediments until rifting opened the Pacific Ocean, additional sedimentation occurred until a subduction zone formed off the coast. This uplifted the region out of the sea and created a line of volcanoes, the crust started to pull apart, creating the current Basin and Range landform. Valleys filled with sediment and, during the wet times of glacial periods, with lakes, in 2013, Death Valley National Park was designated as a dark sky park by the International Dark-Sky Association. There are two valleys in the park, Death Valley and Panamint Valley. Both of these valleys were formed within the last few million years, the result of this shearing action is additional extension in the central part of Death Valley which causes a slight widening and more subsidence there.
Uplift of surrounding mountain ranges and subsidence of the floor are both occurring. The uplift on the Black Mountains is so fast that the fans there are small
The term mountaineering describes the sport of mountain climbing, including ski mountaineering. Hiking in the mountains can be a form of mountaineering when it involves scrambling, or short stretches of the more basic grades of rock climbing. All require experience, athletic ability, and technical knowledge to maintain safety, mountaineering is often called Alpinism, especially in European languages, which implies climbing with difficulty such high and often snow and ice-covered mountains as the Alps. A mountaineer with such great skill is called an Alpinist, many cultures have harbored superstitions about mountains, which they often regarded as sacred due to their proximity with heaven, such as Mount Olympus for the Ancient Greeks. In 1492 Antoine de Ville, lord of Domjulien and Beaupré, was the first to ascend the Mont Aiguille, in France, with a team, using ladders. It appears to be the first recorded climb of any technical difficulty, in 1573 Francesco De Marchi and Francesco Di Domenico ascended Corno Grande, the highest peak in the Apennine Mountains.
During the Enlightenment, as a product of the new spirit of curiosity for the natural world, in 1741 Richard Pococke and William Windham made a historic visit to Chamonix. By the early 19th century many of the peaks were reached, including the Grossglockner in 1800, the Ortler in 1804, the Jungfrau in 1811, the Finsteraarhorn in 1812. In 1808 Marie Paradis became the first female to climb Mont Blanc and this inaugurated what became known as the Golden age of alpinism, with the first mountaineering club - the Alpine Club - being founded in 1857. Well-known guides of the era include Christian Almer, Jakob Anderegg, Melchior Anderegg, J. J. Bennen, Michel Croz, in the early years of the golden age, scientific pursuits were intermixed with the sport, such as by the physicist John Tyndall. In the years, it shifted to a more competitive orientation as pure sportsmen came to dominate the London-based Alpine Club and this ascent is generally regarded as marking the end of the mountaineering golden age.
By this point the sport of mountaineering had largely reached its modern form, with a body of professional guides, mountaineering in the Americas became popular in the 1800s. In North America, Pikes Peak in the Colorado Rockies was first climbed by Edwin James, though lower than Pikes Peak, the heavily glaciated Fremont Peak in Wyoming was thought to be the tallest mountain in the Rockies when it was first climbed by John C. Frémont and two others in 1842, pico de Orizaba, the tallest peak in Mexico and third tallest in North America, was first climbed by U. S. military personnel which included William F. Raynolds and a half dozen other climbers in 1848. Heavily glaciated and more technical climbs in North American were not achieved until the late 19th, in 1897 Mount Saint Elias on the Alaska-Yukon border was summitted by the Duke of the Abruzzi and party. But it was not until 1913 that Mount Mckinley, the tallest peak in North America was successfully climbed by Hudson Stuck, Mount Logan, the tallest peak in Canada was first summitted by a half dozen climbers in 1925 in an expedition that took more than two months.
In 1879-1880 the exploration of the highest Andes in South America began when English mountaineer Edward Whymper climbed Chimborazo, the summit of Aconcagua was finally reached on January 14,1897 by Swiss mountaineer Matthias Zurbriggen during an expedition led by Edward FitzGerald that began in December 1896. The Andes of Bolivia were first explored by Sir William Martin Conway in 1898 and it took until the late 19th century for European explorers to penetrate Africa
