This is a smallish state park (330 acres) in western Kansas that protects (via the Nature Conservancy) dramatic Niobrara chalk formations and Great Plains wild buckwheat — which is found only among these formations and nowhere else in the world. A short mile-long trail takes you close to the nearly hundred foot towers and the Smoky Hill River. This is also a rich paleontology area, as many fossilized remains of marine and flying reptiles have been discovered here. The park gets its name because early visitors thought it looked like the ancient walled city of Jerusalem from a distance.
