About this map

The mining history of Okanogan County is etched across the slopes of Palmer Mountain and Gold Hill in this early 1980s survey. The town of Loomis sits at the base of these heights, where the Palmer Mtn Tunnel and a concentration of claims like the Pinnacle Mine, Black Bear Mine, and War Eagle Mine reflect the era's hard-rock extraction legacy. This landscape is defined by the transition from industrial activity to managed conservation within the Sinlahekin Wildlife Recreation Area.

The deep Sinlahekin Valley provides a central corridor for the region's water systems, including Sinlahekin Creek and several small lakes like Ryan Lake. Evidence of earlier settlement remains in the form of scattered Grave sites and an Indian Allotment Boundary near Tunnel Flat. To the west, the terrain rises sharply toward Tillman Mountain and Douglas Mountain, where remote camps like the Highland Fire Camp and South Fork Junction Campground support forestry and recreation.
