History of Petrified


 Petrified wood found in the park and the surrounding region is made up of almost solid quartz. Each piece is like a giant crystal, often sparkling in the sunlight and the rainbow of colors is produced by impurities in the quartz, such as iron, carbon, and manganese.

    Over 200 milion year ago, the logs washed into an ancient river system and were buried quick enough and deep enough by massive amouts of sediment and debris also carried in the water and minerals, including silica dissolved and thousands of year crystallized within the cellular structure, replacing the organic material as it broke down over time.
