These curious basalt prisms, hexagonal in cross-section and up to hundreds of feet tall, have long evoked demonic comparisons. Located within the Ansel Adams Wilderness of the Inyo National Forest, the Devil’s Postpile National Monument is home to these strange geometrical columnar formations as well as Rainbow Falls, a 100 foot waterfall.
