Prehistoric Trackways National Monument

Planning for the Prehistoric Trackways National Monument

The Prehistoric Trackways National Monument was established in 2009 to conserve, protect, and enhance the unique and nationally important paleontological, scientific, educational, scenic, and recreational resources and values of the Robledo Mountains in southern New Mexico. The Monument includes a major deposit of Paleozoic Era fossilized footprint megatrackways within approximately 5,280 acres.

The trackways contain footprints of numerous amphibians, reptiles, and insects (including previously unknown species), plants, and petrified wood dating back 280 million years, which collectively provide new opportunities to understand animal behaviors and environments from a time predating dinosaurs. The site contains one of the most scientifically significant Early Permian track sites in the world.

Location / Access
BLM is developing plans to facilitate public access to the Monument. There are currently no facilities and very few signs for or at the Monument. This website will provide updates about public access as they become available.


Coming from the North (I-25):  At the Dona Ana Exit:  From NM320 (Thorpe Road) in Doña Ana, go west to US 85, then go north about a half a mile to Shalem Colony Road. Turn west on Shalem Colony Trail, which curves to the south. Go about 1.5 miles until you cross over the Rio Grande and take a right onto county road, Rocky Acres Trail.  After turning on Rocky Acres Trail, go approximately ¼ mile and then turn left onto the only dirt road (Permian Track Road) leading to the west.  Cross over a cattleguard and continue to the west.  This road, past about a mile, is for high-clearance, 4wd vehicles only.

Coming from the South (Las Cruces):  Travel on Picacho Ave./Hwy. 70, at the stop light with Shalem Colony Trail. Go north on Shalem Colony Trail for approximately 5.5 miles.  Prior to reaching the Rio Grande, you will reach a county road, Rocky Acres Trail.  Turn west on Rocky Acres Trail.  Go west approximately ¼ mile to a dirt road entrance on the left-hand side.  Cross over a cattleguard and continue to the west.  This road, past about a mile, is for high-clearance, 4wd vehicles only.

The New Mexico Museum of Natural History is located at 1801 Mountain Road NW in Albuquerque. From Interstate 40, take Rio Grande Boulevard south about half a mile to Mountain Road, then east on Mountain Road less than a half a mile to the Museum, turning north on 18th street to the parking lot.
