People are already in North America

about 23,100 years ago

Fossilised human footprints preserved in the mud of an ancient lake at White Sands National Park, New Mexico, were dated in 2021 to between 21,000 and 23,000 years ago, and confirmed with a different technique in 2023. They show that people were living in North America during the Last Glacial Maximum, thousands of years earlier than the 'Clovis-first' model suggested, when an ice-free corridor opened some 13,000 years ago. The footprints belong mainly to teenagers and children, and they provide direct evidence of daily life. Settlement probably came along the Pacific coast.
