Ancient Coastal Footprints on Calvert Island Hint at Early Pacific Migration

Researchers found 29 distinct footprints dating to about 13,000 years ago on Calvert Island, likely from three individuals walking barefoot along the shoreline; the prints are clustered and mostly inland-facing, suggesting a gathering spot rather than a linear path and supporting the idea that early people used Pacific coastal routes to reach North America as sea levels were 6–9 feet lower. Excavation and analysis are ongoing, with findings published in PLOS One.
