Geography

Alberta, with an area of 661,848 km2 (255,500 sq mi) is the fourth largest province after Quebec, Ontario, and British Columbia. To the south, the province borders on the 49th parallel north, separating it from the U.S. state of Montana, while on the north the 60th parallel north divides it from the Northwest Territories. To the east the 110th meridian west separates it from the province of Saskatchewan, while on the west its boundary with British Columbia follows the 120th meridian west south from the Northwest Territories at 60°N until it reaches the Continental Divide at the Rocky Mountains, and from that point follows the line of peaks marking the Continental Divide in a generally southeasterly direction until it reaches the Montana border at 49°N.

The province extends 1,223 km (760 mi) north to south and 660 km (410 mi) east to west at its maximum width. Its highest point is 3,747 m (12,293 ft) at the summit of Mount Columbia in the Rocky Mountains along the southwest border, while its lowest point is 152 m (499 ft) on the Slave River in Wood Buffalo National Park in the northeast.

With the exception of the semi-arid steppe of the southeastern section, the province has adequate water resources. There are numerous rivers and lakes used for swimming, fishing and a range of water sports. There are three large lakes, Lake Claire (1,436 km2 (554 sq mi)) in Wood Buffalo National Park, Lesser Slave Lake (1,168 km2 (451 sq mi)), and Lake Athabasca (7,898 square kilometres (3,049 sq mi)) which lies in both Alberta and Saskatchewan. The longest river in the province is the Athabasca River which travels 1,538 km (956 mi) from the Columbia Icefield in the Rocky Mountains to Lake Athabasca. The largest river is the Peace River with an average flow of 2161 m3/s. The Peace River originates in the Rocky Mountains of northern British Columbia and flows through northern Alberta and into the Slave River, a tributary of the Mackenzie River.

Alberta's capital city, Edmonton, is located approximately in the geographic centre of the province. It is the most northerly major city in Canada, and serves as a gateway and hub for resource development in northern Canada. The region, with its proximity to Canada's largest oil fields, has most of western Canada's oil refinery capacity. Calgary is located approximately 280 km (170 mi) south of Edmonton and 240 km (150 mi) north of Montana, surrounded by extensive ranching country. Almost 75% of the province's population lives in the Calgary–Edmonton Corridor.

Most of the northern half of the province is boreal forest, while the Rocky Mountains along the southwestern boundary are largely forested (see Alberta Mountain forests and Alberta-British Columbia foothills forests). The southern quarter of the province is prairie, ranging from shortgrass prairie in the southeastern corner to mixed grass prairie in an arc to the west and north of it. The central aspen parkland region extending in a broad arc between the prairies and the forests, from Calgary, north to Edmonton, and then east to Lloydminster, contains the most fertile soil in the province and most of the population. Much of the unforested part of Alberta is given over either to grain or to dairy farming, with mixed farming more common in the north and centre, while ranching and irrigated agriculture predominate in the south.

The Alberta badlands are located in southeastern Alberta, where the Red Deer River crosses the flat prairie and farmland, and features deep canyons and striking landforms. Dinosaur Provincial Park, near Brooks, Alberta, showcases the badlands terrain, desert flora, and remnants from Alberta's past when dinosaurs roamed the then lush landscape.
