2024 Map of Conway Ridge

About this map

Conway Ridge dominates this portion of Cascade County, defining the high ground above the surrounding drainage basins. The landscape is characterized by its dramatic geological formations, most notably The Big Sag, a distinctive terrain feature that provides insight into the ancient watercourses and erosional history of this Montana region. The presence of the Missouri River underscores the area's importance as a central corridor for Western movement and natural resource management. This survey offers a contemporary look at the physical geography of the high plains, where the interplay of ridgelines and river systems has dictated land use and transportation routes for generations.
