The Horse Creek Station site is most likely located on the west bank of Horse Creek, about two miles northeast of Lyman, in Scotts Bluff County. The station served as a stop for the Pony Express.  Several sources identify Horse Creek as a station, which, according to Mattes, possibly also served at one time as the site of Joseph Robidoux's second trading post.
