About this map

The Yellowstone River and the Burlington Northern railroad form the primary east-west corridor of this 1983 survey, anchoring a network of small ranching and rail settlements across Rosebud and Treasure Counties. The map reveals a landscape defined by dramatic geological breaks such as Gumbo Ridge and Rattlesnake Buttes, giving way to the productive grounds of Mission Valley and Sevenmile Flat.

Detailed drainage patterns from the Musselshell River and Big Porcupine Creek illustrate the water sources critical to the region's isolated outposts like Mosby, Sumatra, and Ingomar. Significant infrastructure includes the local airport at Tillitt Field 831 and traces of an Old Railroad Grade, providing a record of shifting transportation routes through the high plains before the late-century era of Interstate expansion.
