Oklahoma Online Masters
Oklahoma, constituent state of the United States of America. It borders Colorado and Kansas to the north, Missouri, and Arkansas to the east, Texas to the south and west, and New Mexico to the west of its Panhandle region. In its land and its people, Oklahoma is a state of contrast and the unexpected. The terrain varies from the rolling, timbered hills of the east to the treeless high plains that extend from the Panhandle region into Texas and New Mexico. Oklahoma’s east-central region is dominated by the lowlands of the Arkansas River, sweeping in from Colorado and Kansas, and by the Red River, which forms nearly all its southern border with Texas. The capital is Oklahoma City, near the center of the state. Since its admission in 1907 Oklahoma became the 46th state of the union.
