1966 Map of Gem Peak

About this map

The Idaho Montana State Line bisects this mid-1960s terrain, marking a boundary where the Kaniksu National Forest meets the Coeur d'Alene National Forest. This montane landscape is defined by its high-elevation landmarks, including Gem Peak with its prominent Lookout Tower and the nearby Eighty Peak radio facility. Settlement is sparse, with human activity primarily represented by industrial and logistical outposts such as the Holliday Mine and a high-altitude Heliport near Rice Creek. Drainage patterns are intricate, with several major watercourses like Shoshone Creek and West Fork Pilgrim Creek carving through the steep topography. A network of primitive paths, including the Stevens Ridge Trail and Loveland Peak Trail, provide the primary access through these protected forest lands.
