Relief map of Manitoba
Manitoba is bordered by the provinces of Ontario to the east and Saskatchewan to the west, the territory of Nunavut to the north, Northwest Territories at a quadripoint to the northwest, and the US states of North Dakota and Minnesota to the south. Manitoba is at the centre of the Hudson Bay drainage basin, with a high volume of the water draining into Lake Winnipeg and then north down the Nelson River into Hudson Bay. This basin's rivers reach far west to the mountains, far south into the United States, and east into Ontario. Major watercourses include the Red, Assiniboine, Nelson, Winnipeg, Hayes, Whiteshell and Churchill rivers. Most of Manitoba's inhabited south has developed in the prehistoric bed of Glacial Lake Agassiz. This region, particularly the Red River Valley, is flat and fertile; receding glaciers left hilly and rocky areas throughout the province.
The province has a saltwater coastline bordering Hudson Bay and more than 110,000 lakes, covering approximately 15.6 percent or 101,593 square kilometres (39,225 sq mi) of its surface area. Manitoba's major lakes are Lake Manitoba, Lake Winnipegosis, and Lake Winnipeg, the tenth-largest freshwater lake in the world. A total of 29,000 square kilometres (11,000 sq mi) of traditional First Nations lands and boreal forest on Lake Winnipeg's east side were officially designated as a UNESCO World Heritage Site known as Pimachiowin Aki in 2018.
Baldy Mountain is the province's highest point at 832 metres (2,730 ft) above sea level, and the Hudson Bay coast is the lowest at sea level. Riding Mountain, the Pembina Hills, Sandilands Provincial Forest, and the Canadian Shield are also upland regions. Much of the province's sparsely inhabited north and east lie on the irregular granite Canadian Shield, including Whiteshell, Atikaki, and Nopiming Provincial Parks.
Extensive agriculture is found only in the province's southern areas, although there is grain farming in the Carrot Valley Region (near The Pas). Around 11 per cent of Canada's farmland is in Manitoba.
Climate[edit]

Deep Lake at Riding Mountain National Park
Manitoba has an extreme continental climate. Temperatures and precipitation generally decrease from south to north and increase from east to west. Manitoba is far from the moderating influences of mountain ranges or large bodies of water. Because of the generally flat landscape, it is exposed to cold Arctic high-pressure air masses from the northwest during January and February. In the summer, air masses sometimes come out of the Southern United States, as warm humid air is drawn northward from the Gulf of Mexico. Temperatures exceed 30 °C (86 °F) numerous times each summer, and the combination of heat and humidity can bring the humidex value to the mid-40s. Carman, Manitoba, recorded the second-highest humidex ever in Canada in 2007, with 53.0. According to Environment Canada, Manitoba ranked first for clearest skies year round and ranked second for clearest skies in the summer and for the sunniest province in the winter and spring.
Southern Manitoba (including the city of Winnipeg), falls into the humid continental climate zone (Köppen Dfb). This area is cold and windy in the winter and often has blizzards because of the open landscape. Summers are warm with a moderate length. This region is the most humid area in the prairie provinces, with moderate precipitation. Southwestern Manitoba, though under the same climate classification as the rest of Southern Manitoba, is closer to the semi-arid interior of Palliser's Triangle. The area is drier and more prone to droughts than other parts of southern Manitoba. This area is cold and windy in the winter and has frequent blizzards due to the openness of the Canadian Prairie landscape. Summers are generally warm to hot, with low to moderate humidity.
Southern parts of the province, just north of Tornado Alley, experience tornadoes, with 16 confirmed touchdowns in 2016. In 2007, on 22 and 23 June, numerous tornadoes touched down, the largest an F5 tornado that devastated parts of Elie (the strongest recorded tornado in Canada).
Köppen climate types of Manitoba
The province's northern sections (including the city of Thompson) fall in the subarctic climate zone (Köppen climate classification Dfc). This region features long and extremely cold winters and brief, warm summers with little precipitation. Overnight temperatures as low as −40 °C (−40 °F) occur on several days each winter.

Flora and fauna[edit]
Polar bears are common in northern Manitoba.
Manitoba natural communities may be grouped within five ecozones: boreal plains, prairie, taiga shield, boreal shield and Hudson plains. Three of these—taiga shield, boreal shield and Hudson plain—contain part of the boreal forest of Canada, which covers the province's eastern, southeastern, and northern reaches.
Forests make up about 263,000 square kilometres (102,000 sq mi), or 48 percent, of the province's land area. The forests consist of pines (jack, red, eastern white), spruces (white, black), balsam fir, tamarack, poplars (balsam, trembling aspen), birches (white, swamp), and small pockets of eastern white cedar.
Two sections of the province are not dominated by forest. The province's northeast corner bordering Hudson Bay is above the treeline and considered tundra. The tallgrass prairie once dominated the south-central and southeastern regions, including the Red River Valley. Mixed grass prairie is found in the southwestern region. Agriculture has replaced much of the natural vegetation, but prairie can still be found in parks and protected areas; some are notable for the presence of the endangered western prairie fringed orchid.
Manitoba is especially noted for its northern polar bear population; Churchill is commonly referred to as the "Polar Bear Capital". In the waters off the northern coast of the province are numerous marine species, including the beluga whale. Other populations of animals, including moose, white-tailed deer, mule deer, black and brown bears, coyote, cougar, red fox, Canada lynx, and grey wolf, are distributed throughout the province, especially in the provincial and national parks.
There is a large population of red-sided garter snakes near Narcisse; the overwintering dens there are seasonally home to the world's largest concentration of snakes.
Manitoba's bird diversity is enhanced by its position on two major migration routes, with 391 confirmed identified species; 287 of these nest within the province. These include the great grey owl, the province's official bird, and the endangered peregrine falcon.
Manitoba's lakes host 18 species of game fish, particularly species of trout, pike, and goldeye, as well as many smaller fish.
