About this map

Loomis serves as the primary hub in this Okanogan County landscape, where the Loomis Post Office marks the center of local activity near the banks of Sinlahekin Creek. The area's industrial history is well-represented by a cluster of workings on the eastern slopes, including the Pinnacle Mine, Security Mine, and the War Eagle Mine. Significant infrastructure projects like the Palmer Mountain Tunnel and Sinlahekin Dam Number Three illustrate the long-term human modification of this terrain for mining and water management.

Water defines the geography, with Toats Coulee Creek and Cecil Creek carving through the highlands toward the valley floor. Recreational and forestry sites such as the South Fork Junction Campground and Highland Fire Camp are situated near high points like Quartz Mountain and Douglas Mountain. This 2011 survey captures the enduring footprint of mining operations alongside more modern conservation and recreation areas in northern Washington.
