Bow River in the context of "Canadian Rockies"

The Blackfoot Confederacy, Niitsítapi, or Siksikáí'tsitapi (ᖹᒧᐧᒣᑯ, meaning "the people" or "Blackfoot-speaking real people"), is a historic collective name for linguistically related groups that make up the Blackfoot or Blackfeet people: the Siksika ("Blackfoot"), the Kainai ("Many Chiefs") or Blood, and two sections of the Peigan or Piegan or Piikani ("Splotchy Robe") – the Northern Piikani (Aapátohsipikáni) and the Southern Piikani (Amskapi Piikani or Pikuni). Broader definitions include groups such as the Tsúùtínà (Sarcee) and A'aninin (Gros Ventre) who spoke quite different languages but allied with or joined the Blackfoot Confederacy.

Historically, the member peoples of the Confederacy were nomadic bison hunters and trout fishermen, who ranged across large areas of the northern Great Plains of western North America, specifically the semi-arid shortgrass prairie ecological region. They followed the bison herds as they migrated between what are now the United States and Canada, as far north as the Bow River. In the first half of the 18th century, they acquired horses and firearms from white traders and their Cree and Assiniboine go-betweens. The Blackfoot used these to expand their territory at the expense of neighboring tribes.

Calgary (/ˈkælɡəri/) is the largest city in the Canadian province of Alberta. As of 2021, the city proper had a population of 1,306,784 and a metropolitan population of 1,481,806, making Calgary the third-largest city and fifth-largest metropolitan area in Canada.

Calgary is at the confluence of the Bow River and the Elbow River in the southwestern portion of Alberta, in the transitional area between the Rocky Mountain Foothills and the Canadian Prairies, about 80 km (50 mi) east of the front ranges of the Canadian Rockies, roughly 299 km (186 mi) south of the provincial capital, Edmonton, and approximately 240 km (150 mi) north of the Canada–United States border. The city anchors the south end of the Statistics Canada-defined urban area, the Calgary–Edmonton Corridor.

Banff National Park is Canada's first national park, established in 1885 as Rocky Mountains Park. Located in Alberta's Rocky Mountains, 110–180 kilometres (68–112 mi) west of Calgary, Banff encompasses 6,641 square kilometres (2,564 sq mi) of mountainous terrain, with many glaciers and ice fields, dense coniferous forest, and alpine landscapes. 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. The main commercial centre of the park is the town of Banff, in the Bow River valley.

The mountains were formed from sedimentary rocks that were pushed east over newer rock strata, between 80 million and 55 million years ago. Over the past few million years, glaciers have at times covered most of the park; today they 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. Archaeological evidence at Vermilion Lakes indicates presence of Indigenous peoples for more than 10,000 years in the Banff area.

The Nelson River is a river of north-central North America, in the Canadian province of Manitoba. The river drains Lake Winnipeg and runs 644 kilometres (400 mi) before it ends in Hudson Bay near Port Nelson. Its full length (including the Saskatchewan River and Bow River) is 2,575 kilometres (1,600 mi), it has mean discharge of 2,370 cubic metres per second (84,000 cu ft/s), and has a drainage basin of 1,072,300 square kilometres (414,000 sq mi), of which 180,000 square kilometres (69,000 sq mi) is in the United States.

The Elbow River is a river in southern Alberta, Canada. It flows from the Canadian Rockies to the city of Calgary, where it merges into the Bow River. Its name is derived from the elbow-like turn the river takes before it joins the Bow.
