LeFlore County is mainly in the Arkansas Valley and the Ouachita Mountains physiographic sections. Topography differences range from the nearly level flood plains of the Arkansas, Poteau, and Kiamichi rivers and major creeks to the steep mountainous areas in the southern part of the county. Most of the drainage is into the Poteau and Kiamichi Rivers by way of creeks and streams.
Soil, water, timber, coal, natural gas, stone and gravel, fish, wild game, and scenic beauty are the main natural resources of the county.
Soil, the most important natural resource in the county, produces pasture and hay, timber, and crops. Farm ponds are a source of water for livestock and are used for fish production. Sandstone is the most common surface rock in the area (it is excavated and used in building construction). Fishes, wildlife, and game are abundant. Crappie, bass, and catfish are the most common fishes in lakes and rivers. The habitat has abundant cover and food for deer, dove, turkey, quail, squirrel, and duck and for fur-bearing animals such as mink, beaver, fox, and bobcat.
