Arches National Park is just as its name implies, home to more than 2,000 natural arches which have been created by erosion in the desert climate. In addition to the sandstone arches the park is also full of rock bridges, towers and rock fins and spires that make hiking its trails or exploring its canyons a naturalist’s delight. Erosion in Arches has also created potholes throughout the desert that serve as watering holes to an abundance of wildlife, including some rare and endangered species.
