A major route for emigrants, freighters, the military, stagecoaches and mail, the Overland Trail across present southern Wyoming saw heavy traffic in the 1850s and 1860s. At different stations along the way, coach drivers obtained fresh horses, the wives of station masters fed dusty travelers and soldiers fought attacking warriors.
