Little Jerusalem Badlands State Park showcases a mile-long stretch of 100-foot-tall spires and cliffs of eroded Niobrara Chalk, a layer of rock deposited about 85 million years ago. Niobrara Chalk was formed by sediment that settled at the bottom of an inland ocean called the Western Interior Seaway which covered most of central North America roughly 140 to 70 million years ago. The sediment became compressed over time, and the seaway floor was lifted by the same tectonic shifting that formed the Rocky Mountains. 

Little Jerusalem Badlands State Park was established by the Kansas Legislature in 2018 and opened to visitation in 2019. The 332-acre park encompasses 220 acres of badlands – fragile, but ruggedly spectacular geologic formations--owned by The Nature Conservancy (TNC) and adjacent to TNC's 18,000-acre Smoky Valley Ranch. The Nature Conservancy will continue to own Little Jerusalem with the Kansas Department of Wildlife and Parks partnering to manage visitor access and use.

The park is the largest expanse of exposed Niobrara Chalk formation in Kansas. Smaller Niobrara Chalk outcrops are commonly seen along U.S. 83 Highway between Oakley and Historic Lake Scott State Park. Monument Rocks is a well-known Niobrara Chalk landmark east of Little Jerusalem.

Little Jerusalem Badlands State Park is a unique, vital habitat for a variety of wildlife and plants. Ferruginous hawks nest here and rock wrens and Says’ phoebes, common in arid parts of the western U.S., keep an eye out for insects. Sharp-eyed visitors will occasionally spot small mammals, bats, lizards, snakes, toads and a variety of insects. Great Plains wild buckwheat grows only in the chalk prairies of western Kansas and the single largest population of this endemic plant is found at Little Jerusalem.

Little Jerusalem Badlands State Park is a day-use park only, open from sunrise to sunset daily, all year round. 

Little Jerusalem Badlands State Park is a fragile landscape. The Niobrara Chalk formations are soft and easily damaged by the weather and by climbing and walking on them. As a result, KDWP and The Nature Conservancy are managing visitor access to avoid harming the delicate environment. Enjoy the landscape, but leave no trace behind of your time in the park.
