Overview

The Devils Postpile formation is a rare sight in the geologic world and ranks as one of the world’s finest examples of columnar basalt. Its columns tower 60 feet high and display an unusual symmetry. Another wonder is in store just downstream from the Postpile at Rainbow Falls, once called “a gem unique and worthy of its name.” When the sun is overhead, a bright rainbow highlights the spectacular falls.

Devils Postpile landscape is a reflection of fire and ice. The eruption and uniform cooling of basalt lava created an impressive wall of columns. Later a glacial event exposed the columns and polished smooth the top of this formation enhancing the pattern of hexagons that are a result of the mineral composition of the lava.
