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 region of human geography, referring to the Plains Indians or the Plains States.

Climate In general, the Great Plains have a wide variety of weather through the year, with very cold winters and very hot summers. Wind speeds are often very high. The prairies support an abundant wildlife in undisturbed settings. Humans have converted much of the prairies for agricultural purposes or to create pastures.

The 100th meridian roughly corresponds with the line that divides the Great Plains into an area that receive 20 inches or more of rainfall per year and an area that receives less than 20 in. In this context, the High Plains, as well as Southern Alberta, south-western Saskatchewan and Eastern Montana are mainly semi hot steppe land and are generally characterized by rangeland or marginal farmland.

It is bound on the east by the Mississippi River Valley and on the west by the Rocky Mountains, an area almost five times as large as the state of Texas.

The Rocky Mountains (or the Rockies) are a major mountain range in western North America. The Rocky Mountains stretch more than 3,000 miles (4,830 km) . The Rocky Mountains were formed from 80 million to 55 million years ago by the Laramie progeny. Since then, erosion by water and glaciers have sculpted the mountain range into dramatic valleys and peaks. At the end of the last ice age, humans started to inhabit the mountain range.

Currently, much of the mountain range is protected by public parks and forest lands, and is a popular tourist destination, especially for hiking, camping, mountaineering, fishing, hunting, skiing, and snowboarding.

Mississippi River is the largest river system in North America. Flowing entirely in the United States, it rises in western Minnesota and meanders slowly southwards for 2,530 miles (4,070 km) to the Mississippi River Delta at the Gulf of Mexico. With its many tributaries, the Mississippis watershed drains all or parts of 31 U.S. states between the Rocky and Appalachian Mountains and even reaches into southern Canada. The Mississippi ranks fourth longest and tenth largest among the worlds rivers.

In the immense region , there are main geographic environments – the more fertile tall grass areas of Missouri and Arkansas, and the arid short grassland regions of Texas, Kansas and Colorado.

Kansas is a U.S. state located in the Midwestern United States. It is named after the Kansas River which flows through it, which in turn was named after the Kansa Native American tribe, which inhabited the area. Kansas is the 15th most extensive and the 33rd most populous of the 50 United States

Colorado is a U.S. state that encompasses most of the Southern Rocky Mountains as well as the northeastern portion of the Colorado Plateau and the western edge of the Great Plains. Colorado is part of the Western United States, Southwestern United States, and the Mountain States.

Texas is the second most populous and the second most extensive of the 50 United States, and the most extensive state of the 48 contiguous United States. The name, based on the Caddo word Texas meaning friends or allies, was applied by the Spanish to the Caddo themselves and to the region of their settlement in East Texas. Located in the South Central United States.

Before Europeans arrived in the area, Native people were primarily agricultural and the region was probably sparsely populated.

The buffalo was not the mainstay of life.

After the introduction of horses and guns, the buffalo became the dominant leans of subsistence and populations living on or near the Plains borders moved out onto the Plains to hunt.

Buffalo numbered more than 25 million during much of the nineteenth century and they migrated annually to the West and North in the spring, and to the East and South in the fall Many Native people followed the herds.

Numerous other animal species shared their way of life – antelopes, pronghorns, deer, bears, and all sorts of small animals and birds.

There is evidence of a drought occurring during 1500 A.D. when many changes in life occurred.

Great Plains of North America has always been and will be the place attracts many tourists. This is an unforgettable place for its surprising beauty.
