About this map

Ellensburg Pass serves as a critical geographic marker in this section of central Washington, where the high desert terrain of the Kittitas and Yakima county line meets the complex drainage systems of the eastern Cascades. The map reveals an intricate network of deep-cut drainages, including Stone Quarry Canyon, Reed Canyon, and Horse Trough Canyon, which feed into the primary waterways of Manastash Creek and Umtanum Creek.

Evidence of local water management is seen in the S Br Canal and its S Br Extension in the northeast, while the southern portion is dominated by the prominent east-west rise of Umtanum Ridge. This landscape is defined by its canyon systems and the high-elevation roads that traverse them, such as Ridge Road and Umptanum Road, providing a clear picture of the area's topographical barriers and natural transit corridors.
