A volcanic plateau of lakes, meadows, and old-growth forests in the southern Washington Cascades.
Indian Heaven Wilderness is a protected federal wilderness area located within the Gifford Pinchot National Forest in southwestern Washington state. The designation covers a broad, forested volcanic plateau studded with more than 150 small lakes, ponds, and marshes, and scattered with meadows that weave between numerous volcanic peaks. The landscape is a defining expression of the Indian Heaven volcanic field, a Quaternary basalt field that forms part of the southern Washington Cascades. The area has long held deep cultural meaning for Native peoples of the Pacific Northwest. The plateau was originally known as 'Sahalee Tyee' and has served as a gathering place for the Yakama, Klickitat, Cascades, Wasco, Wishram, and Umatilla tribes for approximately nine thousand years. Indigenous use of the land for berry picking, fishing, and hunting continues to shape the area's identity today. Now formally protected, the wilderness combines dramatic Cascade scenery, wildlife habitat, cultural heritage, and accessible hiking. The Pacific Crest National Scenic Trail passes through its heart, and the broad volcanic viewpoints offer rare sights of four major Cascade volcanoes in a single panorama. This combination of natural and cultural richness makes Indian Heaven a distinctive destination within the U.S. National Wilderness Preservation System.
