1965 Map of Addy Mountain

About this map

The Colville Valley and the northern reaches of the Iron Mountains define this mid-1960s survey of Stevens County. The landscape is a study in resource management and extraction, dominated by the sprawling Little Pend Oreille Game Range and the Colville National Forest. The Great Northern railroad follows the course of the Colville River in the west, while an Old Railroad Grade to the east suggests earlier timber or mining routes through the foothills. Local history is anchored by the community of Arden and the rural Twelvemile Sch, with numerous small-scale mining efforts indicated by scattered Prospect and Well labels near Castle Rock and The Butte. These features show a rugged Stevens County economy transitioning from early 20th-century pioneers toward modern forestry and wildlife conservation.
