Nature & Science

Petrified Forest National Park is located in the greater Painted Desert—they are not two separate parks. While the Painted Desert encompasses about 1500 square miles, the park is over 200,000 acres—and not desert! Actually the main environment is short-grass prairie or intermountain-basin, semi-arid grassland. It is dry here, but there is snow in the winter and rain during the monsoon. Explore the varied species that make their home in this demanding environment.
