'''Tatshenshini-Alsek Park''' or '''Tatshenshini-Alsek Provincial Wilderness Park''' is a [[List of British Columbia provincial parks|provincial park]] in [[British Columbia, Canada]] (9,580&nbsp;km²). It was established in 1993 after an intensive campaign by Canadian and American conservation organizations to halt mining exploration and development in the area, and protect the area for its strong natural heritage and biodiversity values.
'''Tatshenshini-Alsek Park''' or '''Tatshenshini-Alsek Provincial Wilderness Park''' is a [[List of British Columbia provincial parks|provincial park]] in [[British Columbia]], Canada. The park is {{convert|9,580|km2|sqmi|abbr=on}} in size. It was established in 1993 after an intensive campaign by Canadian and American conservation organizations to halt mining exploration and development in the area, and protect the area for its strong natural heritage and biodiversity values.
 
The park is situatedlocated in the very northwestern corner of British Columbia, bordering the American state of [[Alaska]] and the Canadian [[Yukon Territory]]. It nestlesNestled between the Yukon's [[Kluane National Park and Reserve]] in the Yukon and [[Glacier Bay National Park and Preserve|Glacier Bay]] &and Alaska's [[Wrangell-StWrangell–St. Elias National Park and Preserve|Wrangell-StWrangell–St. Elias]] [[National Park]]s and Preserves, the park includes all land in AlaskaBritish Columbia west of the [[Haines Highway]]. It is part of the [[Kluane-Wrangell-St. Elias-Glacier Bay-Tatshenshini-Alsek]] park system, and in 1994 was designated as a [[UNESCO]] [[World Heritage Site]].
 
==History==
Over the centuries, numerous indigenous peoples lived in this area, including the historic [[Tlingit people|Tlingit]] and [[Southern Tutchone]], who built fishing villages along the rivers. The eastern edge of the park follows an ancient trade route used by the [[Chilkat]] tribe(a Tlingit people) to barter with the [[Tutchone]].
 
In the mid-19th century, the sudden breakup of a natural dam on the [[Alsek River]] caused a severe flood. The dam had been formed by the advance of a glacier across the entire Alsek River channel; the obstructed river formed a large temporary lake upstream of the blockage. A wall of water {{convert|7 metres |m|ft|abbr=on}}&nbsp;high and {{convert|15 metres |m|ft|abbr=on}}&nbsp;wide swept an entire Tutchone village into the sea at Dry Bay, killing all the inhabitants.
 
Tatshenshini-Alsek was one of the last areas of British Columbia to be mapped and explored. In the 1960s the first geological exploration for minerals took place in the area. Significant copper deposits were found in the vicinity of Windy Craggy Mountain, in the middle of the Tatshenshini region. In the mid-1970s two companies began rafting the [[Tatshenshini River|Tatshenshini]] (aka "the Tat", a term also used to refer to the region) and Alsek rivers for the first time. In the mid-1980s a proposal surfaced to develop Windy Craggy peak into a huge open-pit mine.

In 1991 Tatshenshini International was established, linking together the top 50 conservation organisations in North America. An extremely intensive campaign followed in Canada and in the United States, particularly the [[U.S. Congress]] and eventually the [[White House]], when the active involvement of then Vice-President [[Al Gore]] was enlisted. Eventually, BC Premier [[Mike Harcourt]] responded by undertaking a review of the issues surrounding Tatshenshini-Alsek by the Commission on Resources and the Environment (CORE). BC government under Premier Harcourt decided in June 1993 to protect Tatshenshini-Alsek as a Class A park. The owners of the Windy-Craggy mineral claims were given a $103.8 million settlement.
 
In combination with the adjoining national parks, this completed protection of the world's largest international park complex. The International Union for the Conservation of Nature ([[IUCN]]) proposed the area for protection as a UNESCO World Heritage Site. The [[Kluane-Wrangell-St. Elias-Glacier Bay-Tatshenshini-Alsek]] transfrontaliertransborder park system comprising [[Kluane National Park and Reserve|Kluane]], [[Wrangell-StWrangell–St. Elias National Park and Preserve|Wrangell-StWrangell–St. Elias]], [[Glacier Bay National Park and Preserve|Glacier Bay]] and [[Tatshenshini-Alsek Park|Tatshenshini-Alsek]] parks, was declared a [[UNESCO]] [[World Heritage Site]] in 1994 for the spectacular glacier and icefield landscapes, in addition to the importance of its habitat for [[Grizzly Bear|grizzly bearsbear]]s, [[Reindeer|caribou]] and [[Dall Sheep|Dall sheep]].
 
In 1999, a party of sheep hunters found artifacts and remains of a young male at the foot of a glacier in the park; he was later called [[Kwäday Dän Ts’ìnchi]], or "Long Ago Man Found". The well-preserved frozen body turned out to be between 300 and 550 years old.

== Geography and geology ==
==Wildlife==
The [[Alsek River|Alsek]] and [[Tatshenshini River|Tatshenshi]] rivers flow through the park in glacier-carved U-shaped valleys. These valleys through the coastal mountains allow cool, moist ocean air into the cold interior. The quick change from ocean to interior environment, frequent floods, landslides and avalanches, a varied geology and great elevation changes have together created an exceptionally diverse range of habitat conditions for the local flora and fauna.
 
The [[Alsek Ranges]] intersect the park, and [[Mount Fairweather]], at {{convert|4,671|m|ft}}, is the province's highest peak. The Tatshenshini-Alsek area lies in a region of high earthquake activity. Slippages along the [[Fairweather Fault|Fairweather]] and Hubbard/Border [[Geologic fault|Faults]] to the west and the [[Denali Fault]] to the north cause regular earthquakes.

The quick change from ocean to interior environment, frequent floods, landslides and avalanches, a varied geology and great elevation changes have together created an exceptionally diverse range of habitat conditions.
Tatshenshini-Alsek Park supports a large [[grizzly bear]] population. A green area that cuts through a barrier of mountain and ice connects coastal and interior grizzly bear populations and provides valuable habitat. The park is the only Canadian home of the [[glacier bear]]. This extremely rare blue-grey colour phase of the [[American black bear|black bear]] is found only within the park and just over the border into the United States.
 
As well as bears, Tatshenshini-Alsek Park also supports [[Dall's sheep]], and exceptional numbers of [[mountain goat]]s, Kenai [[moose]], grey [[wolf|wolves]], eagles ([[Bald eagle|bald]] and [[Golden eagle|golden]]), [[falcon]]s ([[peregrine falcon|peregrine]] and [[Gyrfalcon|gyr]]), and [[trumpeter swan]]s. Along the coastline, [[sea lion]]s and [[humpback whale]]s can be seen.

[[Pleasant Camp, British Columbia]] is on the southeastern edge of Tatshenshini-Alsek Provincial Park, near the Alaskan border. Pleasant Camp has a dry-summer [[subarctic climate]] ([[Köppen climate classification]]: '''Dsc''').
Alsek Ranges are situated there and [[Mount Fairweather]], at 4,663 metres is the province’s highest peak. The Tatshenshini-Alsek area lies in a region of high earthquake activity. Slippages along the Fairweather and Hubbard/Boarder [[Geologic fault|Faults]] to the west and the [[Denali Fault]] to the north cause regular quakes.
