1922 Map of Colockum Pass

About this map

The Wenatchee Mountains and the high ridge of Colockum Pass dominate this 1920s-era landscape, where the rugged terrain of eastern Washington drops toward the banks of the Columbia River. The map reveals a remote ranching and rural agricultural economy, punctuated by isolated schools such as the Tarpiscan School and Whisky Dick School. Numerous family-named homesteads including the Sheridan Ranch and Osborn Ranch are clustered near the vital water sources of Colockum Creek and Naneum Creek.
