Banff National Park is Canada’s oldest national park, established in 1885 in the Rocky Mountains.
The park, located 110–180 kilometres (68–112 mi) west of Calgary in the province of Alberta, encompasses 6,641 square kilometres (2,564 sq mi) of mountainous terrain, with numerous glaciers and ice fields, dense coniferous forest, and alpine landscapes. The Icefields Parkway extends from Lake Louise, connecting to Jasper National Park in the north. Provincial forests and Yoho National Park are neighbours to the west, while Kootenay National Park is located to the south and Kananaskis Country to the southeast.
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.
Johnston Creek is a tributary of the Bow River in Canada’s Rocky Mountains. The creek is located in Banff National Park.
Johnston Creek originates north of Castle Mountain in a glacial valley southwest of Badger Pass and south of Pulsatilla Pass, at an elevation of 2,500 meters (8,200 ft). The creek flows southeast between Helena Ridge and the Sawback Range, and then south through a gorge known as Johnston Canyon. The stream empties into the Bow River, south of Castle Mountain, between Banff and Lake Louise, at an elevation of 1,440 meters (4,720 ft).
As Johnston Creek approaches the Bow River, it flows through a large canyon formed by erosion over thousands of years. The creek has cut through the limestone rock to form sheer canyon walls, as well as waterfalls, tunnels, and pools.
A popular hiking trail follows the canyon and leads to a meadow within the Johnston Valley above the canyon. The first part of the trail consists of a constructed walkway with safety rails and bridges, while the last part of the trail is natural and more rugged. Within the meadow are the Ink Pots, which are six blue-green spring-fed pools.
Ice climbing is a popular activity on the frozen waterfalls in winter. (Description from Wikipedia).
