Monument Rocks

50 feet chalk formations with fossils


Yes, In Kansas!

"Chalk" full of fossils and rising up to 50 feet above ground, and descending 300 feet below, this natural formation was created during the late Cretaceous Period of geologic history. The area was covered by the Western Interior Seaway which extended from the present day Gulf of Mexico north through Canada. When the sea receded, it left behind these magnificent marine sedimentary deposits that have eroded over time. Every inch represents 700 years of history!  

In 1968 Monument Rocks was designated as the first National Natural Landmark in Kansas and in 2006 was voted one of the 8 Wonders of Kansas


Monument Rocks plays an important role in the history of the Smoky Hill Valley area.  In the 1860's, The Butterfield Overland Despatch (BOD) trail, also known as the Smoky Hill Trail, used these rocks as a landmark to guide travelers through the region along the trail.  Fort Monument (1865-1868) was established about one mile southwest to protect the trail, but there are no remains of the "fort" today.
