Banff National Park
Banff National Park is Canada's oldest national park, established in 1885 in the Rocky Mountains. The park, located 110–180 kilometres west of Calgary in the province of Alberta, encompasses 6,641 square kilometres of mountainous terrain, with numerous glaciers and ice fields, dense coniferous forest, and alpine landscapes. The mountains are formed from sedimentary rocks which were pushed east and over newer rock strata between 80 and 55 million years ago. Over the past few million years, glaciers have at times covered most of the park, but today are found only on the mountain slopes though they include the Columbia Icefield, the largest uninterrupted glacial mass in the Rockies. Erosion from water and ice have carved the mountains into their current shapes.
