In 2021, researchers scanning a New Mexico lakebed found 23,000-year-old human footprints that rewrote the oldest chapter of American history

Remarkable fossilized footprints discovered in New Mexico’s White Sands National Park have pushed back human presence in North America by thousands of years. Dated between 21,000 and 23,000 years old, these ancient tracks of adults and children walking alongside Ice Age megafauna challenge the long-held Clovis-first model, offering a vivid glimpse into early human life and survival.
