1985 Map of Lone Man Coulee East

About this map

Marias River and its major tributaries carve through the Montana high plains at the intersection of the Pondera and Teton County lines. This 1985 survey captures a landscape defined by sharp elevation shifts between the high Benton Bench and the deep incisions of Lone Man Coulee. The terrain is characterized by the erosive forces that created prominent landmarks like Castle Rock, while the more recent human presence is marked by infrastructure developments. Modern resource extraction and agriculture are evident through the numerous Gravel Pits, Storage Bins, and a Pipeline network connecting to a Pumping Station. The hydrological complexity of the region is further illustrated by the confluence of the Dry Fork Marias River and Spring Creek, showing how water management and natural drainages dictate the local land use patterns during the mid-1980s.
