2024 Map of Granite Pass

About this map

The Bitterroot Mountains form a high-altitude spine along the border of Idaho and Montana, defined here by the jagged divide between Clearwater National Forest and the lands of Mineral and Missoula counties. The terrain is dominated by the steep drainages of Crooked Fork and Boulder Creek, which carve deep valleys below prominent summits like Granite Peak and Pilot Knob. Significant for both boundary history and recreation, the State Line (Granite Peak) Trl and White Creek Divide Trl follow the high ridges, marking the historic separation of these mountain territories. The drainage network is dense, including Pebble Creek and Hopeful Creek, illustrating the complex hydrology of this high-country landscape near the state line.
