About this map

Naneum Ridge and Jumpoff Ridge dominate this high-country landscape in Kittitas County, where the transition between the Wenatchee National Forest and the Colockum State Wildlife Area is marked by deep drainages and remote high passes. The 1966 fieldwork, updated with mid-1980s aerial data, shows a network of early transport routes including the Colockum Road and several specialized paths like the Pack Trail and Sheep Trail.

Remote outposts such as Four Corners and Mountain Home provide small human footprints in a territory largely defined by watercourses like Tarpiscan Creek and Cooke Creek. The presence of the Naneum Airstrip near the center of the sheet and a major Pipeline crossing the northern ridges highlights the mid-century infrastructure required to manage these public lands. Historically significant landmarks like Colockum Pass and the rugged depths of Cooke Canyon underscore the difficulty of traversing this section of the Cascades foothills.
