About this map

Colockum Pass serves as the central focal point of this high-altitude landscape in Kittitas County, where the drainages of the Columbia River basin begin their descent. The map reveals a network of remote service roads and mountain tracks, including the winding Jumpoff Ridge Rd and Colockum Rd, which provide access to the high backcountry. Historically significant spots like Mountain Home and the junction at Four Corners suggest a long-standing pattern of seasonal use or land management in this environment.

The hydrology of the region is exceptionally detailed, showing the intricate forks of Tarpiscan Creek and Caribou Creek as they carve through the terrain. From the northern headwaters of Big Stemilt Creek to the southern reaches of Sheep Creek, the map illustrates how water defines the movement through these ridges and canyons. These routes and water sources are vital for understanding the historical land use and early surveying of the Washington interior.
