Oklahoma is a land of contrasts; rolling plains, tall grass prairies, heavily wooded hills, and mountains. Eastern Oklahoma is hilly and mountainous with many clear lakes, rivers, and streams. Central Oklahoma is taken over by rolling prairies and red-soil-tinted lakes and streams. Western Oklahoma is a rugged land dotted by state parks with lodges and camping areas in secluded places. The full range of Oklahoma's history can be seen in forts, battlegrounds, log cabins, a homesteader's sod house, capitols of the Indian nations, and mansions of early Oklahoma merchants and oilmen. Modern Oklahoma gives a glimpse of what frontier America was like, yet offers metropolitan advantages in its cities. (Courtesy of Rand McNally http://www.randmcnally.com)
