1986 Map of Lake Mason NE

About this map

Devils Basin dominates this 1986 survey of central Montana, where the terrain transitions across the boundary between Petroleum and Musselshell counties. The landscape is defined by the drainage patterns of Little Wall Creek to the north and North Willow Creek to the south. This area illustrates a mid-century ranching and resource extraction economy, with scattered corrals indicating active livestock management and a Gravel Pit highlighting local industrial activity. The elevation at Sunlight provides a landmark point amidst the complex ridgelines and coulees that characterize this part of the state before modern large-scale development shifted the rural character.
