About this map

Corral Butte stands at the center of this high-elevation wilderness within the Okanogan National Forest, where a network of seasonal camps and pack trails defined the human footprint in the early 1980s. The landscape is characterized by a complex drainage system, where numerous forks of Twentymile Creek and South Fork Toats Coulee Creek carve through the terrain. The presence of remote outposts like Skull Camp, Thunder Camp, and Irene's Camp suggests a pattern of land use tied to timber management, recreation, or historical grazing, rather than permanent settlement.

Notable landmarks such as the Thirtymile Shelter and the broad expanse of Thirtymile Meadows indicate established routes for travelers navigating the high country. The map also identifies industrial traces like the Borrow Pit near Swamp Creek, alongside natural features such as Long Lake and the prominent Thunder Mtn. This survey provides a clear view of the backcountry infrastructure before modern digital mapping, preserving the locations of specific pack trails and 4WD tracks.
