Wyoming’s role as a central thoroughfare in North American migration is evident in the numerous trails, routes, and corridors that have traversed its varied terrain for centuries. From the early movement of Indigenous peoples seeking game and trade opportunities, to the later influx of Euro-American settlers pursuing farmland, mineral wealth, and new beginnings, these migration paths have shaped the social, cultural, and economic contours of the region.
