found: Wikipedia, Sept. 19, 2013(Great Plains; The Great Plains are a broad expanse of flat land, much of it covered in prairie, steppe and grassland, which lies west of the Mississippi River and east of the Rocky Mountains in the United States and Canada. This area covers parts of the U.S. states of Colorado, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas, and Wyoming, and the Canadian provinces of Alberta, Manitoba and Saskatchewan. The Canadian portion of the Plains is known as the Prairies. Some geographers include some territory of Mexico in the Plains, but many stop at the Rio Grande.)
