2011 Map of Lookout Pass

About this map

Bitterroot Mountains geology and transit history define this rugged borderland between Montana and Idaho. The map documents a landscape heavily influenced by both the mineral industry and the evolution of mountain passage. Mining operations are scattered across the peaks and gulches, including the Snowstorm Mines near Snowstorm Peak and the Bullion Mine south of Bullion Pass. This area has long served as a critical corridor through the Bitterroots, evidenced by the proximity of Mullan Pass and Saint Regis Pass.
