2011 Map of Porcupine Butte

About this map

Porcupine Butte commands this section of Wheatland County, serving as a high-elevation anchor for a complex network of waterways and ranch-road infrastructure. The map details an environment defined by its water management and aviation access, featuring the Cottontail Ranch Airport and the Donald Dam. These elements reflect a landscape adapted for large-scale ranching and private transit in a region where surface water is carefully channeled through features like the Tronrud Ditch. A series of streams, including Sweet Grass Creek, Fish Creek, and the American Fork, drain the surrounding slopes, while named thoroughfares such as Melville Rd and Bill Donald Rd provide the primary connections through the foothills. The presence of Rough Gulch and Basin Creek further illustrates the varied drainage patterns that shape this corner of Montana.
