Ancient Footprints and Sled Tracks Discovered in New Mexico National Park Suggest Early Human Presence

Researchers have discovered ancient human footprints alongside tracks of early sled-like transport in White Sands National Park, New Mexico. The findings indicate human activity dating back approximately 22,000 years. The study suggests that these tracks were left by individuals hauling wooden sleds loaded with goods. While sleds have been used in various cultures worldwide, the White Sands discovery represents the oldest confirmed evidence of their use. The dating of the sled tracks challenges previous assumptions about the timing of human migration to America, potentially pushing it back to around 33,000 years ago. Previously discovered human footprints in White Sands were first recorded in 2017. Subsequent analysis revealed distinctive patterns of adults walking alongside children's footprints, possibly indicating group travel. Some sled tracks show a single, continuous line, suggesting a sled with two parallel wooden runners joined in a triangular form. Others display two parallel grooves, implying a construction resembling an 'X' shape for enhanced stability during transportation. Archaeologists have also found settlements in North America dating back 11,000 years.
