Escalante Petrified Forest State Park is a state park in Utah, United States, located 0.8 km north of Escalante and 71 km east of Bryce Canyon National Park. The park features a high mesa that was once an ancient floodplain. Approximately 135 to 155 million years ago, large trees were buried in mud during floods. Groundwater eventually replaced the organic material with silica, preserving the wood as fossils.
