Researchers found that humans repeatedly occupied White Sands, New Mexico, between about 23,500 and 21,700 years ago despite major climate swings during the last ice age. Footprints cluster around periods of rapid environmental change, but modeling suggests this may partly reflect when geological conditions favored preservation rather than changes in human population. https://www.science.org/doi/10.1126/sciadv.aeh0707
