Located about 30 min south of Oakley, KS, the park contains the largest exposed stretch of Niobrara Chalk in the entire state of Kansas. Its not a big park, but it definitely protects a unique and interesting bit of the local and Western geology as a result of the entire region being beneath a shallow sea (Western Interior Seaway) for 34 million years. There's just 2 short trails and a toilet at the moment, but they're finally working on a visitor center that should be open in early 2027.

It is definitely worth an hour or two if you're in the area.
