Physical Features
Norman is situated within the Great Plains physiographic region, characterized by rolling hills and flat to gently sloping terrain. The city lies on the floodplain of the South Canadian River, which meanders through the area creating fertile bottomlands and several prominent floodplains. The river basin provides irrigation for nearby agricultural lands. The highest point in Norman is approximately 1,300 feet above sea level, while the lowest point is around 1,100 feet, with gentle slopes connecting these areas.
Geological History
The topography of Norman is the result of millions of years of geological processes. During the Permian era, shallow seas covered the region, depositing limestone and sandstone formations. Subsequent uplift and erosion shaped the current landscape. The Great Plains were formed during the Ice Age when glaciers scraped away loose topsoil, leaving behind the rolling hills and valleys that are characteristic of the region. The South Canadian River has played a significant role in shaping Norman’s topography, carving out the river valley and creating the fertile bottomlands. The river’s meandering pattern is indicative of the soft sedimentary rock substrate it has eroded over time.
