Simms was once a cattlemen's town but now is dominated by farmers. Nearby Crown Butte Preserve is reached by taking the county road between Simms and Cascade. This makes a great day trip. Except for an occasional hiker, the ecosystem sits undisturbed about 1,000 feet above the surrounding northern great plains. Although the most striking features of Crown Butte are the rising columns of rock and the wild grasses, the preserve also provides a rich habitat for wildlife.
