About this map

Okanogan National Forest land defines the high-altitude landscape of this 1969 survey, where the drainages of Wolf Creek and the Twisp River carve deep valleys between massive peaks. The terrain is characterized by its glacial geography, featuring Abernathy Ridge, Midnight Mountain, and the curious naming of Three A M Mtn. This map captures the region's wilderness character just as modern recreation infrastructure began to settle in, shown by the placement of Poplar Flat Campground and Mystery Campground along the riverbanks.

Remote backcountry access is preserved through an extensive network of Pack Trails that connect high points like Gardner Meadows to alpine waters such as Slate Lake and Little Slate Lake. The presence of a Borrow Pit near Whistling Creek suggests local maintenance activity for the few unimproved roads that skirt the lower elevations, while the majority of the sheet remains a study in natural drainage patterns, from the North Fork Wolf Cr to the headwaters of Cook Creek.
