Lemmon Petrified Park

Lemmon Petrified Park is an outdoor museum featuring structures and artworks made from petrified wood and fossilized grass across three acres in downtown Lemmon. The site contains more than 100 towers, pyramids, and a castle, all constructed from these ancient materials.

Local businessman Ole Quammen created this geological park in 1932 during the Great Depression as a project that provided work for the community. The initiative employed dozens of local workers and offered economic relief during hard economic times.

The site displays structures built from petrified wood that reflect local craftsmanship and the region's relationship with its geological resources. Visitors can observe how artisans transformed natural materials into architectural forms.

The park offers free admission and is open for visitors from late May through early September, making it a seasonal destination worth planning ahead for. Access is located on Main Avenue in downtown and visitors should wear comfortable shoes since there is much ground to cover.

The site holds fossil remains of extinct animals including dinosaur bones and mammoth finds, all gathered from a limited radius around the location. These rare paleontological specimens make it more than just a wood art installation.
