Paleontology is the study of the ancient past through fossils and the geologic record. Fossils are simply the preserved remains or traces of ancient plants and animals.
The Reach Museum in Richland, Washington, focuses on the Hanford Reach area of the Columbia River. The Museum includes a small display of plant fossils from the region.
Petrified Wood
Among the evidence of ancient life uncovered by paleontologists is petrified wood. When silica-rich waters, often from volcanic ash deposits, replaces and preserves the cell structure of buried trees, the result is petrified (silicified) wood.
