The Inland South, Natural Features

Ozark plateau, coniferous trees, Ouachita Mountains, rolling plains, mixed forest

The region consists of rolling plains and hills covered by grassland and mixed forest. It includes the foothills of the Appalachians and the hill lands south of the Ozark plateau and the Ouachita Mountains. Elevations range from 50 feet in the south to 600 feet in the east, west, and north. The underlying rocks near the coast consist of unconsolidated sediments, while the interior has a section of older, crystalline rocks.

Soils of moderate fertility support a fast-growing cover of mainly coniferous trees, such as the southern pine, which is able to reach full growth in 20 years. In some areas, such as the Black Belt of Alabama and Mississippi and the Black Waxy Prairie of central Texas, deep, dark, naturally fertile soils support productive agriculture. Alluvial soils, which are deposited by the area’s many large rivers, are also dark, rich in nutrients, and highly productive.
