2017 Map of Colockum Pass

About this map

Colockum Pass serves as a central geographical marker within this high-elevation landscape, where the northern reaches of the Wenatchee National Forest meet the drainage basins of Kittitas County. The terrain is defined by prominent divides such as Naneum Ridge and Jumpoff Ridge, which separate a complex network of seasonal and perennial waterways. This 2017 survey details the intricate descent of several creek systems, including the Big Stemilt Cr and the branching headwaters of Tarpiscan Cr. Land use and accessibility are documented through established corridors like Coleman Creek Rd and the Ryegrass Ranches Rd, providing a clear view of the rural infrastructure and ranching tracts in the Cooke Canyon vicinity during the early twenty-first century.
