2024 Map of Pender Coulee

About this map

The Lake Mason National Wildlife Refuge dominates this central Montana landscape, where the southern foothills of the Little Snowy Mountains give way to a network of seasonal drainages and high plains. This contemporary survey details a remote section of Musselshell Co, centered on the alkaline waters of Miller Lake and the eponymous Pender Coulee. The map illustrates a high-desert drainage pattern where water is the primary architect of the land, featuring named sources like Big Spring and the meandering paths of Whoop-Up Creek, Jones Creek, and Willow Creek. Human activity is marked by isolated corridors such as Snowy Mountain Rd and Pronghorn Ranch Rd, reflecting the expansive ranching and conservation character of the region. This document serves as a precise guide to the modern boundaries of protected wetlands and the rugged topography of the Snowy Mountain front.
