Available in PDF, EPUB and Kindle. Book excerpt: During the Triassic period 225 million years ago, the Petrified Forest National Park of northern Arizona was a lowland drained by meandering streams carrying sediment to a nearby sea. Rapid burial of trees in oxygen-poor sands promoted petrification as silica-rich groundwater replaced the woody material; hence the petrified wood for which the Park is renowned. This text provides a brief description of the geology and geologic features ¿ slump blocks, basaltic agglomerate, syncline, sand dunes, badlands, and more ¿ that make the Park and environs a geologic wonderland.
