The only time we’re grateful for erosion is when we gaze upon the Chalk Pyramids, also known as Monument Rocks. It’s situated west of the Castle Rock area in Gove County and is the only remnant of the vast inland sea that existed some 80 million years ago. Today, it’s the first natural landmark in Kansas, designated in 1968. Even though it’s located on private range-land, the owners have been kind enough to share it with the public.

Once existing as limestone on the floors of an inland sea, various elements of nature and the erosion of the sea bed, carved these sedimentary formations as the sea dried away.

You can only visit Chalk Pyramids during the day. Since it’s on private property, it’s crucial to adhere to the rules.
Jason McDonald/Alltrails
Visiting the site after dark is prohibited. Flying drones, digging, and carving into the rocks are also strictly prohibited. You have to be careful not to do anything to harm the rocks. It’s also important to refrain from littering; if you can, pick any trash lying around.

We can assure you that the formations are incredible, a true wonder of beauty in the open plains. At sunrise, they’re even more spectacular as the sun hits rocks. But please remember to adhere to the rules and read the signs to keep Chalk Pyramids open to the public.
