Chalk Pyramids in Kansas

By Linda Tancs

The first landmark in Kansas chosen by the U.S. Department of the Interior as a National Natural Landmark, Monument Rocks are a series of large chalk formations in Gove County, Kansas. Voted one of the eight wonders of Kansas, these natural formations were created during the Late Cretaceous Period of geologic history and are rich in fossils. About 20 miles south of Oakley, they rise up to 50 feet above ground and descend 300 feet below. Note that this natural wonder is located on private property made accessible to the public.
