About this map

Joint Base Lewis-Mcchord occupies the southern portion of this high-desert landscape in Kittitas County. The terrain is characterized by a series of dramatic geographic depressions and elevations, including Schnebly Coulee, Rocky Coulee, and Ryegrass Coulee, which all direct seasonal drainage toward the Columbia River to the east. These geological features reveal a complex network of canyons and ridges, such as Middle Canyon and Lone Star Ridge, that define the arid transition from the central Washington plains to the river's edge.

Transportation through this area is anchored by the Vantage Hwy, which skirts the base of Hult Butte and Ryegrass Mtn. Water sources are vital but scattered in this environment, represented by named points like Rock Spring and Sagebrush Spring, and larger drainages including Whiskey Dick Creek and Spring-Cayuse Creek. This modern survey provides an exact record of topographic relief and federal land use in a region primarily defined by its physical geography rather than urban development.
