USGS Topo · Published 1967About this map
The Similkameen River carves a deep valley through the northern Okanogan highlands in this mid-century survey, crossing the Canada United States border near Nighthawk. The landscape is a complex network of mining claims and rugged peaks, where the Great Northern railroad follows the river's path to serve the region's mineral wealth. Dozens of specific mines are documented, including the Golden Zone Mine and the Horn Silver Mine, illustrating the intense prospecting history along the slopes of Chopaka Mountain and Ellemeham Mtn.
