Helena National Forest lands dominate this part of the Big Belt Mountains, where a dense network of gulches and trails illustrates the area's intricate drainage and topography. Central to the map is the deep namesake Hellgate Gulch, which is flanked by family-named terrain like Harris Gulch, Kilgallon Gulch, and Collins Gulch. These features, along with Sheriff Gulch and Bilk Gulch, point toward a history of local prospecting and livestock grazing common in this part of Montana.
