Current archeological evidence of human habitation on Turtle Island begins.
Date: 21,000 BCE
The earliest archeological evidence of human habitation on Turtle Island available at the time of writing in 2022 is the footprints found at White Sands National Park in present-day New Mexico, which date back to 23,000-21,000 years ago. Due to the fact that much of what is referred to today as Canada and the northern United States is still covered by an ice sheet during this period, this aforementioned evidence indicates that migration down from the Bering land bridge is not the only way that humans arrived on Turtle Island.
