The dates range in age and confirm human presence over at least two centuries with the earliest tracks dating from around 23,000 years ago, which corresponds to the height of the last glacial cycle– making them the earliest recognized human footprints in the Americas.
Human footprints supply unquestionable proof of presence and also of habits. The footprints show a much earlier migration of people into the Americas.
” The footprints left at White Sands give a photo of what was taking place, teens connecting with younger children and grownups,” said Matthew Bennett, Bournemouth University, who assisted lead the study.
In order to examine the site, the team pioneered non-invasive geophysical techniques led by Thomas Urban, research study scientist in the College of Arts and Sciences, and with the Cornell Tree Ring Laboratory.

” Detection and imaging with nondestructive innovation has significantly expanded our capability to study these exceptional footprints in their broader context,” Urban said. “Now we have a distinct window into life during the Pleistocene in North America, and this brand-new study supplies the first unquestionable evidence of a sustained human presence in the Americas thousands of years earlier than the majority of archaeologists thought was likely.”
The footprints inform a fascinating tale of what life was like at this time, state the researchers. Judging by their size, the tracks were left primarily by teens and younger children, with the periodic grownup. Animal tracks– massive, huge ground sloth, alarming wolves, and birds– are present.
” It is an important website due to the fact that of all of the trackways weve discovered there reveal an interaction of human beings in the landscape together with extinct animals,” stated co-author Sally Reynolds of Bournemouth University. “We can see the coexistence between humans and animals on the site as a whole, and by being able to precisely date these footprints, were building a greater picture of the landscape.”
Human footprints supply indisputable proof of presence and also of habits. The footprints show a much earlier migration of human beings into the Americas.
” The footprints left at White Sands give an image of what was taking location, teens communicating with younger adults and children,” stated Matthew Bennett, Bournemouth University, who helped lead the research study. “We can consider our forefathers as rather functional, hunting and enduring, but what we see here is likewise activity of play, and of various ages coming together. A real insight into these early individuals.”

Footprints found at White Sands National Park in New Mexico offer the earliest unequivocal proof of human activity in the Americas and provide insight into life over 23,000 years ago.
The footprints were formed in soft mud on the margins of a shallow lake that now forms part of Alkali Flat, a big playa at White Sands. Scientists from the U.S. Geological Survey dated these tracks utilizing radiocarbon dating of seed layers above and below the footprint horizons. The dates range in age and confirm human presence over at least 2 millennia with the oldest tracks dating from around 23,000 years earlier, which corresponds to the height of the last glacial cycle– making them the oldest known human footprints in the Americas.
The research, released in Science today (September 23, 2021), was carried out by researchers from Cornell, Bournemouth University, the National Park Service, U.S. Geological Survey, and the University of Arizona. The tracks at White Sands were very first discovered by David Bustos, resources manager at the park.
