Alberta is bordered by British Columbia to the west, Saskatchewan to the east, the Northwest Territories to the north, and the U.S. state of Montana to the south. This guide explains Alberta’s regions, landforms, climate, and key geographic facts to support long-term understanding of the area of Alberta.
Defining the area of Alberta
The area of Alberta refers to the province’s total surface area measured in square kilometers, including all land and inland water within its boundaries. Geography and natural features shape Alberta’s character, from the Rocky Mountains in the west to vast prairies in the east. Alberta covers about 661,848 square kilometers, with diverse ecosystems, climate zones, and economic regions. Understanding the area of Alberta involves examining its regions, major rivers, mountain systems, and how these features influence settlement, industry, and environment.
Regions of Alberta
Within the area of Alberta, several geographic and cultural regions help organize the province’s communities and economies. These regions reflect differences in landforms, climate, industry, and lifestyle. Alberta is commonly divided into regions such as Northern Alberta, Central Alberta, Southern Alberta, and the Mountain and Foothill regions associated with the Rockies. Each region contributes uniquely to the province’s identity and resource base.
Northern Alberta
Northern Alberta lies below the boreal forest and contains some of the province’s largest lakes, including Lake Athabasca and Lesser Slave Lake. This region covers a significant portion of the area of Alberta and is important for forestry, oil and gas, and Indigenous communities. Major rivers such as the Athabasca River flow through this area, supporting transportation and natural resource extraction.
Central Alberta
Central Alberta features parkland, farmland, and mixed forest, forming a transition between the northern boreal and southern prairie. It is part of the broader area of Alberta and supports agriculture, energy production, and diverse wildlife. Cities such as Red Deer act as service and transportation hubs within this region.
Southern Alberta
Southern Alberta is known for drier conditions, extensive prairie, and a strong agricultural economy. Within the area of Alberta, this region includes major urban centers like Calgary and is influenced by the Rocky Mountains, which affect weather patterns and water resources. The southern part of the province plays a key role in energy, farming, and trade.
Mountain and Foothill regions
The western portion of the area of Alberta includes the Rocky Mountains and their foothills, characterized by high peaks, valleys, and significant scenic and ecological value. These areas attract tourism and outdoor recreation while also influencing Alberta’s climate, watersheds, and biodiversity.
Geography and landforms
The geography within the area of Alberta ranges from high mountain summits to broad plains and boreal forest. The Rocky Mountains define the western edge, with peaks such as Mount Columbia and numerous provincial parks protecting significant landscapes. East of the mountains, foothills give way to prairie, while in the north, boreal forest and wetlands dominate. Rivers like the Peace, Athabasca, and Saskatchewan flow through Alberta, draining into larger systems and supporting ecosystems and industry.
Climate across Alberta
Climate varies across the area of Alberta due to latitude, elevation, and proximity to mountain barriers. In general, Alberta experiences cold winters and warm to hot summers, with more precipitation in the west and drier conditions in the east. Mountain regions have lower temperatures and higher snowfall, while prairie areas can see wide temperature swings. Understanding local climate patterns is essential for planning, agriculture, and infrastructure within the area of Alberta.
