Monument Rocks & Castle Rock Badlands, Gove County, Kansas

Castle Rock is about 12 miles south of I-70 between Quinter and Collyer, Kansas.

Monument Rocks are names for the same group of rock outcroppings, near US-83 in western Kansas.

Castle Rock Badlands and Monument Rocks are on private range land, but thanks to the owners, open to the public. The United States Department of the Interior has designated the Chalk Pyramids as a National Natural Landmark.
