Chester Butte Unit
At 2,206 acres the Chester Butte unit is located in the middle of Douglas County 7 miles southeast of Mansfield and 13 miles northwest of Coulee City. Elevation ranges from 2,394 feet to 2,070 feet. Shrubsteppe dependent wildlife such as sage thrashers, Brewer’s sparrows, sage sparrows, white-tailed jackrabbits and Washington ground squirrels use the area throughout the year. Greater sage grouse are often seen on the area. In years of high precipitation, there are seasonal ponds and wet meadows that provide habitat for migrating waterfowl. Long-term management objectives are to restore old agricultural fields to native vegetation.

    Unique Features
    The Chester Butte and Dormaier units are located in an area of Douglas County that was extensively affected by glaciation 15,000 years ago. The result is a landscape that features many examples of glacial deposition including eskers, kames, drumlins, erratics (haystack rocks) and a terminal moraine. This moraine, known as the Withrow Moriane, extends across the width of Douglas County from the Columbia River east to Coulee City. So unique are these features within the Columbia Plateau that the National Park Service designated several sites within the county as National Natural Landmarks. The Chester Butte unit and the nearby Dormaier unit are part of the Withrow Moraine and Jameson Lake Drumlin Field National Natural Landmark. Chester Butte is one of the most prominent features within this area.

    For more information on the Withrow Moraine and Jameson Lake Drumlin Field see the following links:
