Glacier National Park, Montana,USA:

Glacier National Park is a national park located in the U.S. state of Montana, on the Canada–United States border with the Canadian provinces of Alberta and British Columbia. The park encompasses over 1,000,000 acres and includes parts of two mountain ranges, over 130 named lakes, more than 1,000 different species of plants and hundreds of species of animals. This vast pristine ecosystem is the centerpiece of what has been referred to as the "Crown of the Continent Ecosystem", a region of protected land encompassing 16,000 square miles.The region that became Glacier National Park was first inhabited by Native Americans and upon the arrival of European explorers, was dominated by the Blackfeet in the east and the Flathead in the western regions. Soon after the establishment of the park on May 11, 1910, a number of hotels and chalets were constructed by the Great Northern Railway. These historic hotels and chalets are listed as National Historic Landmarks, and a total of 350 locations are on the National Register of Historic Places. By 1932, work was completed on the Going-to-the-Sun Road, later designated a National Historic Civil Engineering Landmark, which provided greater accessibility for automobiles into the heart of the park.The mountains of Glacier National Park began forming 170 million years ago when ancient rocks were forced eastward up and over much younger rock strata. Known as the Lewis Overthrust, these sedimentary rocks are considered to have some of the finest fossilized examples of extremely early life found anywhere on Earth. The current shapes of the Lewis and Livingston mountain ranges and positioning and size of the lakes show the telltale evidence of massive glacial action, which carved U-shaped valleys and left behind moraines which impounded water creating lakes. Of the estimated 150 glaciers which existed in the park in the mid-19th century, only 25 active glaciers remained by 2010.Scientists studying the glaciers in the park have estimated that all the glaciers may disappear by 2020 if the current climate patterns persist.Glacier National Park has almost all its original native plant and animal species. Large mammals such as the grizzly, moose and mountain goat, as well as rare or endangered species like the wolverine and Canadian lynx inhabit the park. Hundreds of species of birds, more than a dozen fish species and a few reptile and amphibian species have been documented. The park has numerous ecosystems ranging from prairie to tundra. Notably, the easternmost forests of red cedar and hemlock grow in the southwest portion of the park. Large forest fires are uncommon in the park. However, in 2003, over 13% of the park burned.Glacier National Park borders Waterton Lakes National Park in Canada—the two parks are known as the Waterton-Glacier International Peace Park, and were designated as the world's first International Peace Park in 1932. Both parks were designated by the United Nations as Biosphere Reserves in 1976, and in 1995 as World Heritage sites.According to archeological evidence, Native Americans first arrived in the Glacier area some 10,000 years ago. The earliest occupants with lineage to current tribes were the Salish, Flathead, Shoshone and Cheyenne. The Blackfeet arrived around the beginning of the 18th century and soon dominated the eastern slopes of what later became the park, as well as the Great Plains immediately to the east.The park region provided the Blackfeet shelter from the harsh winter winds of the plains, and allowed them to supplement their traditional bison hunts with other game meat. Today, the Blackfeet Indian Reservation borders the park in the east, while the Flathead Indian Reservation is located west and south of the park. When the Blackfeet Reservation was first established in 1855 by the Lame Bull Treaty, it included the eastern area of the current park up to the Continental Divide.To the Blackfeet, the mountains of this area, especially Chief Mountain and the region in the southeast at Two Medicine, were considered the "Backbone of the World" and were frequented during vision quests.In 1895, Chief White Calf of the Blackfeet authorized the sale of the mountain area, some 800,000 acres, to the U.S. government for $1.5 million with the understanding that they would maintain usage rights to the land for hunting as long as the ceded stripe will be public land of the United States.This established the current boundary between the park and the reservation.
