The Curse of the Petrified Forest
In a small section of the painted desert of Arizona, you can find forests of crumbled trees, preserved as stone. Over 200 million years ago, these large conifers were uprooted by floods, then washed down from the highlands and buried by silt. Water seeping through the wood replaced decaying organic material cell by cell with multicolored silica. The land was lifted up by geological upheaval, and erosion began to expose the long-buried, now petrified wood. In the modern age, the trees have their own stories, having become one of the iconic road trip destinations along Route 66.
