About this map

The northern edge of the Kittitas Valley meets the rising terrain of the eastern Cascades in this topographical study. Water management is a central theme across the landscape, defined by the engineered paths of the North Branch Canal and the Cascade Canal which traverse the valley floor. These human-made arteries intersect natural drainage systems such as Naneum Creek and Schnebly Creek as they flow south from the highlands.

Elevations rise sharply to the north, where the terrain is carved by a series of prominent geological features including Charlton Canyon, Schnebly Canyon, and Cooke Canyon. The transition from the irrigated valley floor to the canyon-strewn uplands is marked by a network of local roads such as Brick Mill Rd and Schnebly Rd, which provide access to the remote northern reaches and landmarks like Naneum Camp Ln.
