2023 Map of Blowout Mountain

About this map

Blowout Mountain and the surrounding high ridges of the Cascade Range define this boundary region between King and Kittitas counties. The landscape is a network of watersheds where the Green River flows westward and Cabin Creek drains toward the Yakima basin. This map documents a high-altitude wilderness split between the Wenatchee National Forest and the Snoqualmie National Forest, connected by a complex system of mountain passes including Sheets Pass, Tacoma Pass, and Green Pass. The legendary Pacific Crest National Scenic Trail winds through the center of the sheet, tracing the spine of the divide. Historical travel and modern recreation paths intersect throughout, from the John Wayne Trail in the north to the Greenwater-Naches Trail and Blowout Mountain Trail further south, illustrating the enduring importance of these corridors.
