1966 Map of Colockum Pass

About this map

Wenatchee National Forest spans this high-elevation landscape in the mid-1960s, defined by the drainage systems of Naneum Creek and Colockum Creek. This region is a network of ridges and canyons, where the remote settlement of Mountain Home and the Naneum Airstrip provided critical outposts for land management and local navigation. The terrain is marked by prominent crossings and features like Colockum Pass and Trough Springs, which have long served as essential waypoints through the rugged divide between the Kittitas and Wenatchee areas. A complex system of transit, including the Colockum Road and several Pack Trails, illustrates the 20th-century reliance on both motorized and traditional travel across Jumpoff Ridge and Naneum Ridge. A prominent Pipeline corridor also traverses the southeastern quadrant, showing the integration of infrastructure into this remote forested area.
