Must see · Geologic Formation · Nature / Park
Monument Rocks (also Chalk Pyramids) are a series of large chalk formations in Gove County, Kansas, rich in fossils. The formations were the first landmark chosen by the US Department of the Interior as a National Natural Landmark. The chalk formations reach a height of up to 70 ft (21 m) and include formations such as buttes and arches. The carbonate deposits were laid down during the Cretaceous Period in what was then the Western Interior Seaway, which split the continent of North America into two landmasses. They are estimated to have been formed 80 million years ago.

  • Stark and beautiful. Very peaceful and accessible. You can drive right up to the rocks, park and walk around the rocks and get a close-up view. Also very nice views of the rocks as you approach. Dirt road and lots of cows, but doable in a regular car. Visit this and skip Castle Rock (in the vicinity, but not as accessible or as safe to get to).
  • Stunning views. We made quick stop on our way to Colorado. Amazing rocks formation. Historic site. Keep that in mind there’s no bathroom or visitor center. You will pass through kissing tree. Truly magnificent
