1983 Map of Thornwood Ranch

About this map

Wolf Creek meanders through the northern reaches of this northeastern Montana landscape, carved by the deep drainage patterns of the Missouri River watershed. This provisional survey highlights the rural character of the high plains in the early 1980s, where the boundary between Sheridan Co and Roosevelt Co bisects the terrain. The namesake Thornwood Ranch stands as a focal point for the area's agricultural history, situated near the headwaters of seasonal waterways. To the west, the distinct topography of Burshia Coulee defines the local relief, illustrating the erosion-carved breaks typical of this ranching country. The map provides a detailed view of the remote ranching infrastructure and natural drainage networks before modern updates, capturing a specific era of land use within the Fort Peck Indian Reservation.
