- Low open valleys parallel to narrow ridges
- Elevations ranges from 700 to 1600 feet above sea level
- Forests and pastures dominate the region
- Limestone and clay soils in the valley
- Shale and sandstone on the ridges
- Northeastern part of state

- Gently sloping hills in north, flatlands in the south
- Hardwood timber, pine, and agriculture
- Red clay and granite base
- Chattahoochee, Flint, Ocmulgee, and Oconee rivers
