<P> Historians David Baird and Danney Goble have searched for the essence of the historical experiences of the people of Oklahoma . They find that, "The shared experiences of Oklahoma's people over time speak of optimism, innovation, perseverance, entrepreneurialism, common sense, collective courage, and simple decency . Those, not victimization, were the core values ." </P> <P> Topographically, Oklahoma is situated between the Great Plains and the Ozark Plateau in the Gulf of Mexico watershed . The western part of the state is subjected to extended periods of drought and high winds in the region may then generate Dust storms . The eastern part of the state is humid subtropical climate zone . The Dry line, an imaginary line that separates moist air from an eastern body of water and dry desert air from the west, usually bisects the state and is arguably an important factor in pre-historic settlement, with agrarian tribes settling in the eastern part of the state and Hunter - gatherer tribes settling in the western part of the state . </P> <P> People have lived in what is now Oklahoma as long as the oldest known documented Paleo - Indian cultures in the field of archaeology / anthropology .
