This Forever stamp was released on June 2, 2016, as part of a pane of sixteen stamps celebrating the centennial of the National Park Service. The stamp series was a tribute to the incredible diversity of landscapes and experiences available within the national park system. The image chosen for Rocky Mountain National Park, taken by photographer Richard McGuire, captures the rugged and alpine heart of the park. It depicts the "Keyboard of the Winds," a dramatic and challenging series of rock pinnacles located on the ridge between Pagoda Mountain and Longs Peak, the park's highest summit. This feature is a well-known objective for experienced mountaineers and embodies the wild, high-altitude character of the park. The name itself evokes the sound of the wind whistling through the rock formations at over 13,000 feet. By featuring this specific, lesser-known but spectacular landmark, the stamp invites a deeper appreciation for the untamed beauty and adventure that Rocky Mountain National Park offers beyond its more easily accessible areas.
