The Flint Hills Geology
Except for catastrophic events such as volcanoes, floods, and earthquakes, much of the Earth’s geology has been created at an imperceptibly slow pace. Millions of years are often required to produce the landscapes we see today throughout the world.
It can be difficult to imagine that the prairie grass was once the mucky bottom of a vast inland sea. If Kansas appeared today as it did 250 million years ago, things would be very different. We would need boats rather than automobiles to get around. Instead of agriculture, fishing might be the main economic industry. In fact most of Kansas would be under water! No reason to build these beautiful limestone buildings. Tallgrass Prairie National Preserve offers us all an opportunity to study this amazing prehistoric past up close, (and on dry land).
Did You Know?
Kansas was once the bed of a vast inland sea. The unique, stairstep landscape of the Flint Hills was formed through a process of differential erosion. Erosion washed away the soft shale layers and left the tougher layers of limestone and flint to form the hilltops and prominent benches.
