Point plotted approximately 2 miles SW of Paxton  

Many historical resources link Alkali Lake Station with the Pony Express. The Alkali Lake Station site is possibly two miles southwest of Paxton, in Keith County, Nebraska. Sources generally agree on its name as Alkali Lake.  In the 1861 Overland Mail Company contract, the station was unnamed.  Merrill Mattes and Paul Henderson believe that Alkali Lake Station served as a home station for the Pony Express.
