2013 Map of Boyle Mountain

About this map

Sawtooth National Forest dominates this high-altitude terrain in Blaine County, Idaho, where deep glacial-cut gulches and canyons define the drainage patterns of the upper Wood River valley system. The map reveals a landscape primarily managed for recreation and natural preservation, centered on the confluence of several major alpine streams. The northern half is oriented around Baker Creek and its eastern fork, providing access to the Baker Creek Campground via Baker Creek Road. To the south, the terrain becomes increasingly steep as it approaches the heights of Boyle Mountain and the prominent Castle Rock. The presence of established sites like Rooks Creek Campground along Warm Springs Creek indicates the long-standing importance of these valley corridors for forest access and seasonal grazing. The nomenclature of features such as Blue Clay Gulch and Boyer Gulch suggests early mining or ranching associations, though by this era, the area is firmly established as public wildland.
