About this map

Manastash Ridge and Umtanum Ridge dominate this central Washington landscape, where the high country transitions into the fertile Kittitas Valley. The map highlights the extensive L T Murray State Wildlife Recreation Area, a vast tract that covers much of the drainage systems for Manastash Creek and Umtanum Creek. Human presence is concentrated along the northern edge, where Manastash Road provides access to local landmarks like Grange and High Valley Ranch.

Significant technical and infrastructure points are noted, including the University of Washington Observatory perched on the ridge and Ellensburg Pass providing a critical crossing point between Kittitas and Yakima counties. The intricate network of canyons, such as Riggs Canyon and Catlin Canyon, illustrates the complex erosion patterns of the basalt plateau. Local services are represented by County Fire Sta No 6, while various borrow pits suggest ongoing road maintenance and local development during this mid-1980s period.
