1893 Map of Big Snowy Mountain

About this map

Big Snowy Mountain dominates the central landscape of this 1880s-era survey, its radial drainage feeding numerous creeks that supported early cattle-range settlements. In this period before extensive rail development in the region, the map documents a network of isolated outposts such as Ubet, Bercail, and Filbrook. The geography is defined by significant natural landmarks like Half Moon Pass and the distinctive Locomotive Butte, which served as critical waypoints for travelers through the Judith Gap. South of the mountain, the Musselshell River meanders through the territory, flanked by the Cayuse Hills. The survey, conducted by E.M. Douglas for the Northern Transcontinental Survey, captures a frontier transition where county lines for Fergus, Meagher, Park, and Yellowstone met in a largely unsettled territory.
