1988 Map of Boyd Mountain

USGS Topo · Published 1988

About this map

Lolo National Forest encompasses this rugged stretch of Mineral County, where the steep topography of Boyd Mountain overlooks a landscape shaped by historical transport and extraction. The St Regis River serves as the primary drainage, joined by numerous tributaries including Twentuemile Creek and Twomile Creek. Industrial history is etched into the terrain via the Old RR Grade, which follows the river valley, marking the path of former rail operations that once served this timber and mineral-rich region. Local mining activity is evidenced by the Ben Pitt Mines located near Mullan Gulch. The map also details the convergences of the North Fork and South Fork, illustrating the complex drainage network that defines this part of the Bitterroot Range during the late twentieth century.
