Kansas Prairie

Photo: Bison on a prairie during a storm
A herd of bison (foreground) rests on a Kansas prairie as a thunderstorm looms. The Great Plains run through the heart of North America, from southern Canada through the middle of the United States and just into northern Mexico. The Great Plains are divided into shortgrass regions in the super-dry west, mixed-grass in the middle, and tallgrass regions in the wetter east.
