Prehistoric Trackways National Monument

Prehistoric Trackways National Monument preserves one of the world’s most significant Early Permian megatracksites within 5,280 acres of the Robledo Mountains, north of Las Cruces, New Mexico. Visitors can hike along informal trails through rugged desert canyons to view fossilized footprints of amphibians, reptiles, insects, plants, and petrified wood dating to approximately 280 million years ago.  

To preserve these scientifically important fossils, select trackway specimens have been removed and curated at the New Mexico Museum of Natural History and Science, forming the Jerry MacDonald Paleozoic Trackways Collection. Visitors can view these tracks by reserving a public tour of the museum’s Geoscience Collection. The Las Cruces Museum of Nature and Science also features two large trackways from the monument—one 30 feet long and another 15 feet—providing an impressive look at Early Permian life.
