1964 Map of Eddy Mountain

About this map

The Thompson River joins the Clark Fork in this mid-century look at the Sanders County mountain country. Industrial activity is centered on the northern reaches of the Lolo National Forest, where the Copper King Mine, Raven Mine, and Silver King Mine sit high above Buckeye Canyon. This rugged terrain is defined by the Kookoosint Ridge and the Eddy Mountain summit, which is topped with a Lookout. The rail-and-river corridor below is dominated by the Northern Pacific railroad, which follows the river's bend past the small settlement of Eddy. The landscape reflects a legacy of extraction and high-altitude monitoring, with narrow drainages like Outlaw Creek and Quartz Creek carving through the steep slopes toward the valley floor.
