This site is probably near or at the old Fort Mitchell (1864-1868) site, twelve miles west of Ficklin's Springs and about two and one-half miles northwest of Mitchell Pass, near a bend of the North Platte River.  Even though Mabel Loving and Roy Bloss identify Fort Mitchell as a station after Scott's Bluff, other sources generally link the two sites but differ on its function as a relay or home station.  The Oregon Trail Memorial Association placed a granite site marker with their circular bronze Pony Express motif near the North Platte bridge, which stood as late as 1960.
