1999 Map of Illinois Peak

About this map

Illinois Peak stands at the center of this high-elevation terrain along the Montana-Idaho state line, where the Bitterroot Mountains divide the Lolo National Forest, St Joe National Forest, and Clearwater National Forest. The landscape is a network of named gulches and high peaks that reflect a history of hard-rock prospecting. The map records several named operations such as the Silver King Mine, American Gold Mine, and the Superior Mine with its associated tailings. The presence of La Casse Camp and numerous adits suggests a localized mining economy integrated into the drainage systems of Oregon Creek and the North Fork Trout Creek. Travel through this backcountry at the end of the millennium was facilitated by established routes like the Superior Red Ives Ranger Trail, connecting remote drainage basins across high saddles like Miller Saddle.
