Rocks at the preserve and in the surrounding Flint Hills were formed from sediment deposited in a fluctuating shallow sea that covered the region during the Permian Period about million years ago. As the sea rose and fell, different types of sediment were deposited on the sea floor and eventually compressed into different layers of rock—mainly limestones and shales —stacked one on top of the other.
Another rock, chert , helped shape the hills once water started to erode through the layers. Harder than limestone, the chert—also called flint—is interspersed in some of the limestone layers and shows the erosional process wherever it was present. That is, flowing water and other erosional forces wear away chert-less limestone faster than chert-filled limestone. As a result, chert caps and protects the hilltops and also helps form hillside benches—long, narrow strips of fairly horizontal strips of rock bounded by steeper slopes above and below.
Shale, more easily eroded than limestone, forms the steep slopes between the benches. Florence limestone, a rubbly rock layer composed of limestone and chert, caps the highest, more-rounded hills at the preserve. The Threemile and Schroyer limestones also contain some fairly thick layers of chert, with the Threemile forming the shorter, flat-topped hills.
Other limestone units in the area include the Funston and the Cottonwood. Formerly enslaved African Americans who had won their liberation moved to the Kansas as a way to escape slavery and have a life of their own. At the time, Kansas was the very edge of the American frontier.
