I had the joy of attending a cousin's graduation from my alma mater, Kansas State University. The landscape that surrounds Manhattan, KS is one of the most beautiful I've ever experienced. The Flint Hills are an incredible landscape that changes drastically throughout the seasons.

The flat top, rolling hills formed when water began to erode the ancient limestone seabeds, leaving behind the flat deposits of flint that gave the hills their name. Check out National Geographic Photographer Jim Richardson's images to see how it changes through the seasons.
