USGS Topo · Published 2024About this map
The Upper Missouri River Breaks National Monument spans the heart of this landscape in Fergus County, preserving the complex drainage patterns and high ridges that define this stretch of Montana. Central to the topography is Knox Ridge, a prominent dividing feature followed by the unpaved Knox Ridge Rd. The terrain is deeply incised by multiple coulees and creek beds, illustrating the erosive power of the regional watershed.
