1985 Map of Flag Butte

About this map

The Blackfeet Indian Reservation dominates this landscape in northern Montana, where the terrain transitions from the high prominence of Flag Butte to the water-managed plains below. The hydrology of the region is defined by the winding course of the Two Medicine River and the significant presence of Alkali Lake. An intricate network of irrigation infrastructure is visible, including the Badger Fisher Main Canal, M Canal, and N Canal, illustrating the 1980s-era efforts to direct water across the arid landscape. The map also captures the boundary line between Glacier and Pondera Counties, providing a clear record of administrative and topographic features such as Rocky Ridge as they appeared during this mid-1980s provisional survey.
