1997 Map of Gallagher Gulch

About this map

The Continental Divide defines the southwestern boundary of this high-altitude landscape, marking the rugged transition between the Beaverhead National Forest in Montana and the Targhee National Forest in Idaho. The terrain is characterized by the massive spine of the Beaverhead Mountains and White Pine Ridge, where numerous seasonal and year-round water sources like White Pine Spring and Seybold Spring sustain the local ecology. Evidence of historical extraction is scattered across the slopes, with several noted Prospects and Mines indicating the area's prospecting legacy. The drainage network is dominated by Little Sheep Creek and its various forks, while the Scenic Trail provides a route through the backcountry near East Creek Campground. This 1997 revision captures the primitive character of the borderlands, where the administrative lines of the Dillon Ranger District meet the physical reality of the divide.
