Simpson Springs is a former Pony Express Station in the Great Salt Lake Desert of northern Utah. The Pony Express, was an express mail system that operated for a year and a half between 1860 and 1861. It reduced the time required to deliver mail from the East to West Coast to 10 days. However the endeavor quickly proved unprofitable, and was rapidly replaced by the telegraph, which could deliver messages across the continental United States almost immediately.
In the 1930’s and early 40’s Simpson Springs was used as a Civilian Conservation Corps (CCC) camp. The current building on the site, which is a replica of what was originally built by the Pony Express, was constructed in 1975.
