Several sources identify Cottonwood as a station between Nine Mile Station (Ward's) and Horseshoe Creek.  However, Helen Henderson asserts that there were two Cottonwood Stations in the area. According to Henderson, the oldest of the two stations, which was one-half mile from the Badger railroad station, served as the Pony Express station. Cottonwood Creek is often mentioned in diaries and journals of pioneers and military men, as well as the itineraries of stage and Pony Express routes.
