During the mid-nineteenth century, Colorado and New Mexico’s San Luis Valley experienced an influx of migrants, land speculators, American soldiers, and capital. Much like in other borderland regions throughout the American West, their arrival was anything but smooth. As these new arrivals settled alongside an existing population of Utes, many attempted to reimagine the region in ways that supported their own economic ambitions. This article traces two regional identities that white Americans created for the San Luis Valley as they migrated to the region in the 1860s and 1870s, both of which ignored claims laid to the region by existing Indigenous and Nuevomexicano populations. The first imagined the valley as an agrarian paradise that land speculator William Gilpin and his partners created to appeal to white settlers. This article employs text mining and spatial analysis to reconstruct the second, an identity that emerged in Colorado newspapers and defined the region as a thoroughfare to mines farther west. Through digital methods, this article links localized attempts to define the San Luis Valley as a region and to lay claim to its resources to those that occurred in the press from afar. In doing so, it demonstrates the efficacy of digital methods for connecting local borderlands histories to broader regional and national narratives.
