Glacier National Park spans one million acres of protected mountains, glaciers, and lakes. It forms part of the Continental Divide. On Triple Divide Peak, the Continental Divide meets the Northern Divide. Here, water can flow to the Atlantic, Pacific, or Arctic Oceans. Fortunately, people have left the park almost unchanged. The different plants, rare and endangered species, and vast water resources of Glacier National Park make its protection a top priority. In 1932, Rotary Clubs from Canada and the United States worked together to protect Glacier National Park and Canada's Waterton Lakes National Park. Combined, the parks form the first international peace park in the world. Glacier is also designated by UNESCO as a biosphere reserve and world heritage site. Glacier National Park experiences extreme weather changes. Conditions alter as the elevation increases. The warm air of the Pacific Ocean brings precipitation to the western part of the park. In contrast, the Arctic Ocean's cold air makes the northeastern side drier. The air from the Pacific Ocean and Arctic Ocean can collide on the Continental Divide. A blizzard can develop. As a result, these mountains can have 100 inches of annual snowfall. The clashing winds also contribute to extreme temperature changes. A nearby town holds the world record for temperature change. In 1916, Browning's temperature decreased by 100 degrees Fahrenheit in one day! Glacier National Park is indeed a place of contrasts. Glacier National Park's unique combination of lush vegetation, endangered wildlife, and splendid natural landscapes attracts diverse people. Scientists research the impact of global warming on the shrinking glaciers. Interested people learn about Native American traditions. Many visitors drive the popular Going-to-the-Sun Road or take a boat tour to experience a land carved by glaciers. Outdoor enthusiasts can bike, hike, horseback ride, fish, snowshoe, cross-country ski, or go white-water rafting. No matter the season, this vast land of majestic mountains an
