About this map

Jumpoff Ridge and Naneum Ridge dominate this high-elevation landscape within the Wenatchee National Forest during the mid-1960s. The area is characterized by a complex network of seasonal drainages and sharp relief, where Colockum Pass serves as a critical transit point through the high country. Small, isolated outposts like Mountain Home and Four Corners suggest the presence of seasonal ranching, forestry, or recreational activity typical of this part of Kittitas County.

Industrial and utility markers, such as the Pipeline and the high-altitude Naneum Airstrip, reflect how the mid-century infrastructure was adapted to the difficult terrain. The map meticulously details water sources vital for high-country survival, including Trough Springs and numerous unnamed Springs that feed into deep incisions like Cooke Canyon and Stray Gulch. Navigability is defined by many unnamed Jeep Trails rather than established roads, emphasizing the region's character as a working forest and range.
