About this map

Okanogan National Forest dominates this high-altitude terrain, where the Twisp River carves a deep valley through the Cascade Range. The landscape is defined by its network of backcountry trails, including the Wolf Creek Trail and Spirit Trail, which provided access to remote peaks and alpine basins before modern road development was fully realized. Significant landmarks like Buttermilk Butte and Oval Peak anchor the topography, while high lakes such as Star Lake and Duffy Lake mark the glacially carved basins near the Chelan County border.

Industrial and recreational infrastructure is sparse but specific, featuring a Landing Strip and Siphon near the confluence of Wolf Creek and Thompson Creek. Settlement is nearly non-existent, limited to seasonal outposts like Gardner Mdws and established recreation sites such as Black Pine Campground and Mystery Campground. The map reveals a wild landscape transitioning from active resource management to a more established wilderness recreation area in the late 1960s.
