1964 Map of West Fork Butte

About this map

The Montana-Idaho state line divides this high-elevation wilderness where the Lolo National Forest meets the Clearwater National Forest. Strategic high ground is marked by fire towers, including Lookout 6137 atop West Fork Butte and Lookout 7215 further south, overlooking a landscape defined by sharp ridges and deep drainages. The northern portion is characterized by Sally Ridge and the Sally Basin, while the south contains more alpine features like the Lost Park Meadows and the waters of Granite Lake. Historically, travel through this difficult terrain relied on a network of primitive routes, shown here as a Jeep Trail and Pack Trail systems. These paths connect the headwaters of East Fork Lolo Creek and Brushy Fork, tracing the same topographic corridors used for decades by forest rangers and early surveyors.
