About this map

Marysville remains the primary hub in this corner of Lewis and Clark County, anchored by the Marysville Post Office and the Marysville Vol Fire Dept. The landscape is defined by its deep mining history, with a high concentration of operations surrounding Drumlummon Hill, including the Drumlummon Mine, Goldsil Millsite, and the Nine-Hour Mine. To the south, the terrain rises toward Greenhorn Mountain and the strategic Mullan Pass.

Transportation corridors follow the natural topography, with the Mullan Tunnel cutting through the divide near Blossburg. The area is densely packed with historical claims and prospects, from the Penobscot Mine near Bald Butte to the various mining sections along Sawmill Gulch. Waterways like Silver Creek and Greenhorn Creek drain these gold-bearing slopes, illustrating the relationship between the rugged geology and the extractive industry that built these mountain communities.
