This is the 45' spire that sits by itself north of Montezuma Tower and the Three Graces. Pigeon Rock has perhaps the worst rock in the Garden of the Gods, and is recomended only if you either really like choss or want to hit all the summits in Garden of the Gods.
Getting There
Hike towards Montezuma Tower, and look for a climbers trail heading right to the base of the small tower.
