The Overland Trails project, created by the Digital Scholarship Lab at the University of Richmond, is part of the American Panorama series. This interactive digital project visualizes the migration of thousands of emigrants along the Oregon, California, and Mormon Trails in the 1840s and 1850s. The project’s goal is to provide a detailed, data-driven exploration of westward expansion, using emigrant diaries and historical accounts to map the routes, hardships, and experiences of these pioneers. It is primarily intended for historians, educators, students, and history enthusiasts, offering a dynamic way to engage with migration patterns that shaped the nation. Through this work, researchers gained a deeper understanding of how geography, time, and human decisions interacted to define these historical migrations. The project uses interactive web mapping technologies, combining geospatial analysis, historical data, and digital storytelling. The Digital Scholarship Lab collaborated with Stamen Design, a firm specializing in data visualization, to create an engaging, user-friendly experience. The project likely took several months or years to complete, given its depth and digital complexity.  A key strength of the project is its interactive design and rich historical integration, making complex migration patterns visually accessible. However, its weaknesses may include data interpretation challenges such as missing or biased historical records and technological accessibility for users unfamiliar with digital tools.  While the Overland Trails primarily focus on western migration, they offer valuable context for regions like Edwardsville, Illinois, which played roles in migration routes and supply chains. The project enhances knowledge by adding depth to well-known historical narratives and reinforcing the scale and complexity of westward expansion. It is a valuable tool for understanding migration’s impact on American history, though some details might still require additional sources for a complete picture.
