1956 Map of Enumclaw

South of the river, the terrain rises sharply toward The Three Sisters and Grass Mountain, where the economy shifts from the Gravel Pits of the valley to high-elevation resource extraction. Deep within the national forest, genealogists and local historians can locate remote mining operations like the Copper King Mine and Queen Bee Mine near Bearhead Mtn. The presence of the Rainier State Sch and various lookout towers like Pinnacle Peak Lookout reflects the region's mid-century development as both a civic center and a monitored forest resource.
