Rising abruptly from the flat Kansas prairie, Monument Rocks are towering sedimentary formations of Niobrara chalk. Created over 80 million years ago during the Cretaceous Period when the region lay beneath the Western Interior Seaway, these structures reach up to 70 feet in height.
Also known as the Chalk Pyramids, this site was the first National Natural Landmark designated by the National Park Service in 1968. Visitors can marvel at the rich fossil record embedded in the soft chalk, which includes remnants of ancient marine life.
Despite being located on private ranch land, the landowners graciously permit public access during daylight hours. The stark contrast of these pale monuments against the vast Kansas sky makes it a premier destination for photographers and road-trippers alike.
