Montana Mine and the Iron Daisy Mine define the industrial footprint of this interior mountain landscape during the late 1980s. This portion of the Lolo National Forest is characterized by intensive mineral exploration, evidenced by numerous adits and prospects scattered across the steep drainages of Prospect Creek. The terrain is carved by a complex network of gulches, including Lucky Boy Gulch, Buster Brown Gulch, and Dirty Gulch, which feed into larger water systems like Crow Creek and the North Fork. A historical Pack Trail winds through the northeast corner, offering a contrast to the modern pipeline and transmission lines that cut through the southern valleys. The presence of a Tailings Pond near Everson Gulch serves as a tangible marker of the area's ongoing mining operations and environmental management at the time of this survey.
