Oklahoma is a state in the South Central region of the United States. It is bordered by the state of Texas on the south and west, Kansas on the north, Missouri on the northeast, Arkansas on the east, New Mexico on the west, and Colorado on the northwest. The state’s name is derived from the Choctaw words okla and humma, meaning “red people”
About Oklahoma in brief

It has 11 distinct ecological regions, with 11 in its borders—more per square mile than in any other state. Its eastern and eastern halves, are marked by extreme differences in geographical diversity: Eastern Oklahoma touches eight regions and western Oklahoma contains three. Although having fewer ecological regions than western Oklahoma, however, its western half contains fewer rare, relic species. The U.S. Geological Survey classifies Oklahoma as one of the most geographically diverse states, with its borders more than twice as wide as the rest of the country. It was the 46th state to enter the union on November 16, 1907, and is the 20th-most extensive and the 28th- most populous of the 50 United States, with 69,899 square miles of land and 1,304 square miles of water. Its highest and lowest point is on the Little River near the far southeastern boundary near the town of Idabel, which dips to 289 feet above sea level. It’s also known informally by its nickname, \”The Sooner State\”, in reference to the non-Native settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889. Oklahoma later became the de facto name for Oklahoma Territory, and it was officially approved in 1890, two years after the area was opened to white settlers. In the Chickasaw language, the state is known as Oklahomma’, in Arapaho as bo’oobe’, Pawnee: Uukuhuúwa, and Cayuga: Gahnawiyoˀgeh.
