About Paul Bunyon's Woodpile
A geologic curiosity - rare in Utah - the "Woodpile" is a cluster of lava logs formed about 30 million years ago during the Eocene Period.
The "logs" were formed when a lava flow cooled into orderly columnar joints having 3 to 6 sides. The columns measure about a foot in diameter and up to 15 feet in length.
This formation was on the rim of the caldera that collapsed due to a void left when lava flowed out from under the caldera. Basin and range faulting caused the formation to tilt onto its side. Erosion has exposed the formation we now see.
