Built in 1858 by Mormon pioneer John Carson beside Camp Floyd Military camp, the Stagecoach Inn served as a hotel and rest stop on the Overland Trail. Horse-drawn carriages carried passengers and mail on a route from St. Louis, Missouri, to San Francisco, California, a trip that took between 22 and 25 days. Samuel Clemens, known as Mark Twain, and his oldest brother traveled the route on their way to Nevada in 1861, and Twain later recalled reaching the remnant and ruin of Camp Floyd. The inn was the first stop on the Overland Route from Salt Lake City to San Francisco and also served as a Pony Express stop for 18 months. Although stagecoach travel declined after the first transcontinental railroad was completed in 1869, the inn continued operating until 1947, serving mainly travelers between Salt Lake City and the mining camps of western Utah and eastern Nevada.
