1. Big Basin Prairie Preserve Marker

Big Basin Prairie Preserve is a 1,818-acre nature preserve managed by the Kansas Department of Wildlife, Parks & Tourism. It is named after the large collapse basin or sink just north of here. This 1-mile diameter, 100-foot deep basin was formed by solution-subsidence, when surface water gains access and dissolves underground deposits of salt, gypsum, or limestone. The overlaying layers of rock and minerals then subside to fill the volume vacated by the water-soluble deposits.

Just east of Big Basin are other collapse features including Little Basin (280 yards diameter, 35 feet deep), and on the side of its rim is a recently-formed deep sinkhole known as St. Jacob's Well, which contains permanent water.

Not Just a Grassland
Big Basin Preserve lies just west of the 100th Meridian, in the zone where tall and mixed grass prairie give way to more drought tolerant short grass prairie. Several mid-grasses predominate the area including little bluestem, buffalo grass and bluegrama. Big bluestem, a characteristic tall grass prairie species, grows in moister areas such as around old sink scars.

Kansas of Really Old

Big Basin Prairie Preserve rest at the western edge of the Red Hills, a region of Kansas with more rugged topography atypical of the Great Plains. Part of the latter Permian Period (~260 million years ago), several thousand feet of brick-red shale, siltstone and sandstones with interbedded layers of gypsum and dolomite were deposited and subsequently exposed through erosion. These iron oxide Permian deposits rust when exposed to oxygen. Look for these bright red soils poking out through the grasses, especially on the sidewalls of the basins.

The Kansas of Recent Old
Big Basin Prairie Preserve is a rocky prairie that appears very similar to how Kansas looked 100 years ago. Bison, a native grassland glazer, range within the Big Basin Prairie Preserve and help to to maintain the natural characteristics of this ecosystem type that has seen dramatic loss in the United States over the past century.

National Distinction
In 1978, the Secretary of the Interior designated this site as the Big Basin Preserve national Natural Landmark (NNL) in recognition of its excellent examples of collapse features, as well as its thriving bluestem-grama (mixed grass) prairie. NNL sites are natural areas that represents the diversity of our nation's natural heritage and are considered the best remaining examples of such features.
