About this map

The Clark Fork river carves a significant path through this section of the Lolo National Forest along the border of Mineral and Sanders counties. The landscape is defined by its industrial and recreational utility at the end of the twentieth century, featuring the St Regis-Paradise Cutoff Road and a designated Scenic Byway that parallels the water. Significant human activity is visible at Donlan Flats and the nearby Ferry Landing Fishing Access, illustrating how the river remains a focal point for local transit and leisure.

Resource extraction history is evidenced by several adit locations, tailings, and a quarry scattered among the steep drainages of Keystone Creek and Slowey Gulch. These small-scale mining marks are found beneath the heights of Keystone Peak and Bald Hill, revealing a terrain where narrow gulches like Firman Gulch and Brian Gulch provided the primary corridors for early mountain industry and exploration.
