Volcanic rocks and landforms reveal the park’s explosive past, and are superimposed on deposits from the Cretaceous Sea, which once connected the Gulf of Mexico with the Arctic Ocean for more than 30 million years. The park includes the largest protected area of Chihuahuan desert ecology in the United States, protecting 1,200 plant species and 450 species of birds. The Rio Grande, which defines the park’s southern border, has carved impressive canyons through these Cretaceous Sea limestone deposits.
