About 22,000 to 23,000 years ago, an individual, most probably a young woman, undertook two perilous journeys separated by several hours, carrying a toddler at least once. The trail they left behind, located in present-day White Sands National Park in New Mexico, spans 1.5 km
and comprises over 400 human footprints, giving the oldest evidence of human presence in the Americas. πhttps://earthlymission.com/white-sands-footprints-new-mexico-study-humans-arrival-north-america-ice-age
