Synopsis

More than 225 million years ago, logs floating in a shallow sea sank to the bottom, were replaced with silica, and became petrified. This and other geologic processes that are part of the Petrified Forest are explained for those who have little, if any, knowledge of geology. It is also useful for geologists.
