Pyramid Peak is a Cascade Range mountain in Washington near Naches Pass on the King-Kittitas county line. Its summit elevation is usually given as 5,646 feet, though some maps show 5,715 feet. Lying close to the Pacific Crest Trail and reached by a branch trail, it has long occupied an important position along a major mountain travel corridor. The peak also figured in the region’s fire lookout system: a series of lookouts stood there beginning in 1923 because it offered broad views over the surrounding forested high country, and the last was destroyed in the early 1960s. Today it is known as a backcountry summit rather than for surviving structures.
