Locations were choosen at road and fence intersections, to be easily found on the map. The general hydrology of the area drains from the south to the north, towards the Ninnescah River. The area adjacent the river is being consumed by the river itself through natural migration. The sediments of both the river banks and the overlying surface cover consist mostly of soft loess and alluvial soils. Even the bedrock, Ninnescah Shale, is composed of a soft red and gray shale with occasional thin limestone beds.
Small tributaries reside in the and easily entrench valleys that slope towards the river.
The stream channels have naturally lowered themselves in response to the downcutting of the Ninnescah River. This system in turn is susseptible to frequent flooding. Marsh and wetland habitats litter the area to provide food and shelter for a variety of animal and bird species. Crop growing fields occupied most of the region south of the natural area unitl recently. A new suburban developement has began immediately across the road from the reservation.
