This was the site of the most eastern remount station of the Central Overland Pony Express in California. Established as a trading post on the Placerville-Carson Road in 1851 by Martin Smith, it became a popular hostelry and stage stop operated by Ephraim 'Yank' Clement. Pony rider Warren Upson arrived here on the evening of April 28, 1860 and, changing ponies, galloped on to Friday's in Nevada to deliver his mochila to Bob Haslam for the ride to Genoa. Used as a pony remount station until October 26, 1861, the station was sold to George D. H. Meyers in 1873.
