The distance from North Jefferson to Tebbetts is 12 miles. The trail passes through Wainwright at milepost 137.6, which was named after a St. Louis financier who helped establish the Missouri, Kansas and Eastern Railroad, later part of the Katy. Although the trail still parallels the Missouri River, it is closer to another mode of transportation, Missouri Highway 94. Bluffs are on the left, and a variety of habitats are on the right. Côte Sans Dessein at milepost 134, or "hill without design (purpose)," runs parallel to the Missouri River. It is about a mile from the trail on the right and is a mile-long ridge, 200 yards wide at the base and 150 feet high. Côte Hill, as it is known locally, is composed of dolomite. One theory suggests that at one time, Côte Sans Dessein was on the south side of the Missouri River. French Canadians settled the Côte Sans Dessein area in 1808, and at that time it was the westernmost settlement in the United States.
