About this map

Wenatchee National Forest spans the northern reaches of this high-elevation landscape, where the crest of Naneum Ridge and Jumpoff Ridge defines the drainage patterns of Kittitas County. The topography is dominated by deep seasonal drainages and steep ridges that converge at Colockum Pass, a critical geographic waypoint for travel through the upland terrain. This 2023 survey illustrates the complex watershed network feeding into major arteries like Big Stemilt Creek and the multiple forks of Tarpiscan Creek.

Forest service roads such as Naneum Ridge Rd and Jumpoff Ridge Rd provide access to the remote backcountry, tracing the natural contours of the land. Lower elevations to the south transition into the drainage of Cooke Canyon and Caribou Creek, showing a landscape shaped by water and timber management. The map details the transition from high-forest zones to the open rangeland near Ryegrass Ranches Rd.
