The Smoky Hills are an upland region of hills in the central Great Plains of North America. They are located in the central United States encompassing north-central Kansas and a small portion of south-central Nebraska. The hills are a dissected plain covered by tallgrass and mixed-grass prairie. The Smoky Hills were formed by sedimentary deposits during the Cretaceous period and consist of chalk limestone and sandstone rock outcroppings.
