Niobrara Formation. Argillaceous chalk, limestone and shale. Chalk is medium gray to white, interbedded with thin layers of chalky shale; contains many fossil clams, oysters, and formanifera. Limestone is light gray to medium gray and yellowish gray, interbedded with medium-gray chalky shale; also contains fossil clams, oysters, and formanifera. These badlands are Kansas’ most dramatic Niobrara chalk formation. They provide unique and important habitat for many plants and wildlife. Native amphibians, reptiles and birds such as ferruginous hawks and cliff swallows live here. Little Jerusalem is also home to the largest population of Great Plains wild buckwheat.
