Prehistoric Trackways National Monument

Prehistoric Trackways National Monument is a nature reserve in the Robledo Mountains containing fossilized footprints of ancient animals embedded in desert rock. The landscape holds traces from amphibians, reptiles, insects, and other organisms that once traveled across this terrain.

The monument preserves traces from creatures that lived roughly 280 million years ago during the Permian period when tropical conditions covered the region. The landscape formed as part of the supercontinent Pangea before becoming the desert terrain visible today.

The preserved footprints reveal how ancient creatures moved and behaved, giving visitors a tangible connection to life from before modern times and helping us understand what walking patterns these animals followed.

The site offers trails and routes for hikers, horseback riders, and vehicles exploring different sections of the monument. Visitors should prepare for desert weather conditions that vary with the season, as temperatures can fluctuate significantly.

The footprints were preserved in sediments that once formed a tropical marine shoreline, revealing how dramatically the region transformed over time. These ancient coastal conditions remain visible in the rock layers today, telling a story of geological change written in stone.
