Palo Duro Canyon State Park
Palo Duro Canyon is a canyon cut by waters of a fork of the Red River. This spectacular canyon contains cross-sectional views of sedimentary rocks representing four geological periods and is an excellent example of a landform that has been created by running water. Triassic and Pliocene vertebrate fossils have been found in the area.
