YouBorn in Volcanic activity approximately 30 million years ago, Paul Bunyan's Woodpile is a unique geologic feature.
Each column is approximately 1 foot in diameter and up to 15 feet in lenght. The columns are three to seven sided depending on slight variations in how the lava cooled.
The Woodpile is also home to an arch. The estimated span of the arch is 20 feet long by 4 feet high. This arch can be seen by hiking farther up the trail and viewing the Woodpile from the side.
