1965 Map of Pea Ridge

About this map

Pea Ridge overlooks an intricate landscape of coulees and drainages within the Charles M Russell and U L Bend National Wildlife Refuges in northern Montana. Surveyed in the mid-1960s with 1980s updates, this map captures a remote section of Phillips County characterized by steep erosion patterns and vital water catchments like Siwash Reservoir and Shale Res. The terrain is defined by a dense network of coulees, including Horse Pasture, Hardpan, and Clayton, which channel seasonal runoff toward Fourchette Creek.
