The breaks are located on the extreme northern edge of Cheyenne County. This area of extremely rough terrain, with its deep ravines and gullies is a marked contrast to the plains generally associated with the area. The breaks were formed by wind deposited sand, silt, and clay particles, called loess.The breaks are 36 miles long and approximately two to three miles wide. They extend into Rawlins County and several miles into Colorado. There are several public roads through the breaks, giving visitors some outstanding viewing sites of this rugged wonder. Visitors are asked to please respect the land owners by remaining on the public roads. Location: Head north from the Benton and Washington intersection in St. Francis, cross the Republican River bridge, and turn right at the first fork. Watch for the numbered red-disk signs as you head north into Nebraska on Road 15 (unpaved). In Nebraska, go west on U.S. 34 to Haigler and turn south to K-27. One of the most outstanding views is about 14 miles north of St. Francis. Copies of the Self-Guided Driving Tour can be picked up at the St. Francis Information Kiosk at the Rest Area on US Highway 36 in St. Francis.
