1954 Map of Hessler Ridge

About this map

The Missouri River defines the northern reaches of this mid-century landscape, carving a wide path through the central Montana plains along the border of Fergus and Phillips counties. This 1954 field survey documents a rugged, unpopulated expanse dominated by the Fort Peck Game Range, where the terrain is heavily dissected by intricate drainage systems. Significant landmarks include the high ground of Hessler Ridge and Galhand Ridge, which separate various coulees and gulches that feed toward the river valley.
