A well-known landmark, readily seen from the Waterton Townsite, this is the Citadel Spire (which is about 350 vertical feet), and what is known as the Citadel Peaks (high point 7,750'), all of which is considered part of Porcupine Ridge. Peak in the distance is Longfellow Peak (8,904')—and a long way off! Photo by Vernon, September 8, 2007.
