The western boundary of the plains is usually well-defined by the abrupt ascent of the mountains.The eastern boundary of the plains is more climatic than topographic. of annual rainfall trends a little east of northward near the 97th meridian.It has an area of approximately 500,000 sq mi (1,300,000 km The term "Great Plains", for the region west of about the 96th and east of the Rocky Mountains, was not generally used before the early 20th century.Nevin Fenneman's 1916 study Physiographic Subdivision of the United States Today the term "High Plains" is used for a subregion of the Great Plains.It covers much of Alberta and southern Saskatchewan, and a narrow band of southern Manitoba.Despite covering a relatively small geographic area, the Prairies are nevertheless home to the majority of each of the three provinces' respective populations.A significant exception to the rule of mature valleys occurs, however, in the case of the Missouri, the largest river, which is broken by several falls on hard sandstones about 50 miles (80 km) east of the mountains.This peculiar feature is explained as the result of displacement of the river from a better graded preglacial valley by the Pleistocene ice sheet.

The present altitude of the plains near the mountain base is 4,000 ft (1,200 m).The term "Great Plains" is used in the United States to describe a sub-section of the even more vast Interior Plains physiographic division, which covers much of the interior of North America.It also has currency as a region of human geography, referring to the Plains Indians or the Plains States.It extends northward from the Mexican boundary far into Canada.Although the altitude of the plains increases gradually from 600 or 1,200 ft (370 m) on the east to 4,000–5,000 or 6,000 feet (1,800 m) near the mountains, the local relief is generally small.
