About this map

L T Murray State Wildlife Recreation Area dominates this landscape, spanning the high ridges and canyons of Kittitas County. The terrain is defined by the massive east-west parallel formations of Manastash Ridge and Umtanum Ridge, which shape the flow of the local watershed. High-altitude scientific activity is marked by the University of Washington Observatory, situated atop the ridge overlooking the basin.

Lower elevations show the transition from wild lands to managed ranching and rural infrastructure. The South Branch Canal and Manastash Creek provide the lifeblood for properties like High Valley Ranch, while the County Fire Sta No 6 serves the scattered residents along Manastash Road. Travelers and researchers can trace the old routes through Ellensburg Pass and the deep cuts of Catlin Canyon and Coleman Canyon, which reveal the complex drainage patterns feeding into the Yakima Valley.
