From Mud Springs, Pony Express riders followed a route that passed through Pumpkin Seed Crossing and southwest of the Court House Rock formation, where the Pony Express station was located.  This site is five miles south and one and one-fourth miles west of Bridgeport, Nebraska. Most sources generally agree on its identity as a C.O.C. & P.P. Express Co. station.
