| Monument Rocks, near Oakley, Kansas © Doug Hickok All Rights Reserved (Click on image for larger view) Looking a bit like a geological tea pot, a butte of chalk rises above the High Plains of Kansas at Monument Rocks. In 1968 these rocky outcrops became the first designated National Natural Landmark in the U.S. Their origins however are much older... This outcrop brews a mixture of 80 million year old fossils with multiple layers of sediment from an ancient inland sea. |
