Located in the Circle Cliffs region of southern Utah, Wolverine Petrified Wood Natural Area contains the petrified remains of a 225 million-year old forest. Found within the Chinle Formation, this layer of sediment was deposited at a time when this region was covered with a thick, steaming tropical rainforest reminiscent of todays Amazon basin. A far cry from the desiccated landscape we see today, this tropical jungle thrived when North America was much closer to the equator than it is today. When a tree fell into the oxygen-poor waters of the swamp, individual cells in the wood were slowly replaced with dissolved minerals in the water until the entire tree was turned to stone.
