History.
Humans have inhabited the area since prehistoric times. According to the "Encyclopedia of Oklahoma History and Culture", the earliest inhabitants were Hunter-Gatherers and Foragers,
peaks of the Sans Bois Mountains are above sea level. Robbers Cave State Park is in the middle of the mountains.
The Poteau River drains the area, and one of its tributaries, Sans Bois Creek, was the namesake for the mountains. Although the mountains have relatively light forests, they do have deposits of coal and natural gas, which provided the basis for economic development in the late 19th and early 20th Centuries.
