Many of the nation's greatest Native American tribes made a living on the Great Plains.  The Great Plains of the United States are located between the Rocky mountains and the Ozarks of the Southeast.  The Plains stretch from the Canadien province of Manitoba to Texas.  They are bordered by the Canadien Shield and the Central Lowlands of the U.S to the East and the Rockies to the West.
     The Great Plains produce tons a grain, lots of livestock and millions of gallons of petroleum a year.  The coal deposits are also very abundant around Texas and northern Mexico.  Some animals that are found on the Great Plains are cobras and bison.  The Great Plains also run through the "4 Corner" states, such as New Mexico and Arizona.
