1966 Map of Silver Butte Pass

USGS Topo · Published 1971

About this map

Silver Butte Pass serves as a critical geographic divide between the Kootenai National Forest to the north and the Kaniksu National Forest to the south. During the mid-1960s, this portion of the Cabinet Mountains was defined by its mineral extraction and extensive pack trail network. Evidence of prospecting activity is prominent at the Viking Mine and Vermillion Mine, alongside several unnamed Prospect sites.
