The Central Plains & Prairie Map
The Central Plains region is often characterized as the
"American Heartland”. Interestingly, from Minneapolis to Little Rock and Memphis, and
the Black Hills to Chattanooga, the Central Plains are far from uniform.
The region spans the rainfall gradients that are a fundamental determining fact
of American geography. Chattanooga averages over 60”, the Oklahoma Panhandle
under 20”. The difference reflects the northern reach of the Gulf of Mexico’s
influence in the southern Central Plains; Lansing, Michigan and Rapid City, South Dakota,get
just over 30” and just under 20” respectively.
This map covers the heart of the Central Mississippi Valley, from the Black Hills in the northwest corner to the great bend of the Tennessee River in Alabama. The map includes the southern portions of South Dakota, Minnesota, Wisconsin, and western Michigan; easternmost Colorado and the Texas Panhandle, nearly all of Oklahoma; Northern Arkansas and western Tennessee and Kentucky; and all of Nebraska, Kansas, Iowa, Missouri, Illinois, and Indiana.
