The Overland Trails, 1840-1860 is one of five maps from American Panorama, a historical atlas project from the Digital Scholarship Lab at the University of Richmond. This specific map traces the experiences of about two dozen American migrants who moved westward during the mid-nineteenth century. Over 2,000 diary entries have been transcribed and organized onto a map according to route (e.g. the Oregon Trail, California Trail, and Mormon Trail). Once visitors select a route, they can examine a list of individuals who kept track of their daily lives while traveling west. In addition, the map provides information about significant historical and political events that occurred concurrently with each diary entry. Mapping the Overlands Trails provides visitors with a way to examine primary documents in context, offering an engaging resource for history classrooms.
