In the heart of southern New Mexico, where the Robledo Mountains rise dramatically above the Rio Grande valley, lies the Prehistoric Trackways National Monument. This expansive site, spanning approximately 5,280 acres, is a treasure trove of Paleozoic Era fossils, offering a glimpse into a world 280 million years old, long before the advent of dinosaurs.
The monument is set within a wedge-shaped block of Permian and Tertiary rocks, its terrain a mix of ancient sediments and volcaniclastic formations. Hikers can trek along the Ridgeline Trail, a 2-mile ascent that leads to the Discovery Site, where the earth reveals its ancient secrets. The tracks of amphibians, reptiles, insects, and even previously unknown species are etched into the stone, a testament to the diverse life forms that once thrived here.
The landscape is characterized by its rugged beauty, with the Robledo Mountains towering over a thousand feet above the valley. The trails, such as the Rocky Acres Trail, weave through a primitive yet captivating terrain that invites exploration. For those interested in more than just hiking, the area also offers opportunities for horseback riding and off-highway vehicle driving.
To preserve these precious fossils, some have been relocated to the New Mexico Museum of Natural History and Science, where they form part of the Jerry MacDonald Paleozoic Trackways Collection. However, local museums like the Las Cruces Museum of Nature and Science also display sections of these ancient trackways.
The region surrounding the monument is rich in local culture and natural beauty. Nearby, the historic Doña Ana Village offers a glimpse into the area’s past, while the city of Las Cruces provides a blend of modern amenities and artisan charm. For travelers, the area is a symphony of ancient history, natural splendor, and contemporary allure, making it an unforgettable destination for those seeking a unique and immersive experience.

Top 3 Facts about Prehistoric Trackways National Monument
The site contains tracks of up to 50 consecutive prints from individual animals, providing clues to animal behavior and interactions in a ancient tropical environment 280 million years ago.
In this ancient landscape, fossilized tracks reveal a vibrant ecosystem from 280 million years ago. Amphibians, reptiles, and insects, including previously unknown species, left their marks on what was once a tropical coastline. Forests of early conifer trees like Walchia, resembling today’s Norfolk Island pine, lined the floodplains. Large plant-eaters like the 10-foot long Pareiasaurs and carnivorous Dimetrodon roamed the shores, while marine fossils of brachiopods, crinoids, and mollusks abound in the strata. This high desert terrain, now dominated by creosote and cactus, offers a unique window into a pre-dinosaur world of remarkable biodiversity.
In the heart of the Rio Grande rift, towering mountains rise over 1,000 feet above the valley, their reddish hues a testament to the Early Permian strata. The landscape, dotted with creosote and ocotillo, contrasts sharply with the cool January highs of 57°F and the scorching June highs of 94°F. Here, ancient trackways etched into the rock tell the story of a pre-dinosaur era, set against a backdrop of dramatic geological formations.
