Cypress Hills (Canada) in the context of "Alberta"

The Wisconsin glaciation, also called the Wisconsin glacial episode, was the most recent glacial period of the North American ice sheet complex, peaking more than 20,000 years ago. This advance included the Cordilleran Ice Sheet, which nucleated in the northern North American Cordillera; the Innuitian ice sheet, which extended across the Canadian Arctic Archipelago; the Greenland ice sheet; and the massive Laurentide Ice Sheet, which covered the high latitudes of central and eastern North America. This advance was synchronous with global glaciation during the last glacial period, including the North American alpine glacier advance, known as the Pinedale glaciation. The Wisconsin glaciation extended from about 75,000 to 11,000 years ago, between the Sangamonian Stage and the current interglacial, the Holocene. The maximum ice extent occurred about 25,000–21,000 years ago during the last glacial maximum, also known as the Late Wisconsin in North America.

This glaciation radically altered the geography north of the Ohio River, creating the Great Lakes. At the height of the Wisconsin Episode glaciation, the ice sheet covered most of Canada, the Upper Midwest, and New England, as well as parts of Idaho, Montana, and Washington. On Kelleys Island in Lake Erie, northern New Jersey and in New York City's Central Park, the grooves left in rock by these glaciers can be easily observed. In southwestern Saskatchewan and southeastern Alberta a suture zone between the Laurentide and Cordilleran ice sheets formed the Cypress Hills, North America's northernmost point that remained south of the continental ice sheets. During much of the glaciation, sea level was low enough to permit land animals, including humans, to occupy Beringia (the Bering Land Bridge) and move between North America and Siberia. As the glaciers retreated, glacial lakes were breached in great glacial lake outburst floods such as the Kankakee Torrent, which reshaped the landscape south of modern Chicago as far as the Ohio and Mississippi Rivers.

Medicine Hat is a city in southeast Alberta, Canada. It is located along the South Saskatchewan River, west of the Saskatchewan border. It is approximately 169 km (105 mi) east of Lethbridge, and 295 km (183 mi) southeast of Calgary. The city and the adjacent Town of Redcliff to the northwest are within Cypress County. Medicine Hat was the eighth-largest city in Alberta in 2021 with a population of 63,271. It is also the sunniest place in Canada according to Environment and Climate Change Canada, averaging 2,544 hours of sunshine a year.

Started as a railway town, today, Medicine Hat is served by the Trans-Canada Highway (Highway 1) and the eastern terminus of the Crowsnest Highway (Highway 3). Nearby communities considered part of the Medicine Hat area include the Town of Redcliff (abutting the city's northwest boundary) and the hamlets of Desert Blume, Dunmore, Irvine, Seven Persons, and Veinerville. The Cypress Hills (including Cypress Hills Interprovincial Park) are a relatively short distance (by car) to the southeast of the city.

Cypress Hills Interprovincial Park is a natural park in Canada straddling the Alberta / Saskatchewan boundary and jointly administered by the two provinces. Located south-east of Medicine Hat in the Cypress Hills, it became Canada's first interprovincial park in 1989.

The park consists of two protected areas, the 345 km (133 sq mi) West Block, that straddles the Alberta / Saskatchewan boundary between Alberta Highway 41, the townsite of Elkwater, Saskatchewan Highway 615, Saskatchewan Highway 271, and Fort Walsh, and the Centre Block, an additional area of 58 km (22 sq mi) in Saskatchewan, west of Saskatchewan Highway 21.
