This site is reportedly one mile west of Melbeta, Nebraska in Scotts Bluff County. The 1861 Overland Mail Company contract listed the site as an unnamed Pony station, later named for Benjamin F. Ficklin, superintendent of the entire Pony Express route.  Other sources also identify Ficklin's Springs as a station. 

The site originated as a Pony Express station and later served as a telegraph station and temporary garrison in 1865. In 1871, cattle rancher Mark M. Coad acquired the sod station.  As late as 1987, a marker stood on Nebraska State Highway 92 identifying the station's visible stone foundations.
