About this map

Marysville sits at the northern edge of this high-elevation terrain, marking a landscape defined by significant mining history and mountain passage. The area is a complex of summits including Mount Belmont and Bald Butte, crisscrossed by the Continental Divide Scenic Trail as it winds along the border of Lewis and Clark and Powell counties. Industrial history is evident in the numerous prospects and mine shafts scattered throughout the gulches, including the Drumlummon works and the Strawberry Mine.

Infrastructure for transportation and energy shapes the southern portion of the map, where the Mullan Tunnel pierces the ridge near Mullan Pass. This pass serves as a historic gateway through the divide, accompanied by a modern pipeline and the small settlement at Blossburg. The seasonal transition of the land is noted by the Belmont Ski Area, while the hydrological network of Silver Creek and Greenhorn Creek drains the surrounding Helena National Forest.
