13,000-Year-Old Footprints Reveal Early Human Life on Pacific Coast
Footprints discovered on the shores of Calvert Island, British Columbia, are providing a rare glimpse into the lives of people who inhabited the Pacific Coast of Canada 13,000 years ago. The 29 distinct prints, preserved in ancient shoreline sediment, offer direct evidence of human activity during the late Pleistocene epoch.
The findings, published in PLOS One, detail impressions of toes, arches and heels corresponding to at least three individuals. Researchers believe the footprints represent a small group moving together along the water’s edge. “Fossilized footprints are rarely found in archaeological contexts,” explained Duncan McLaren, lead author of the study and researcher at the Hakai Institute, “though coastal erosion can occasionally reveal them.”
The location of the discovery is particularly significant. At the time the footprints were made, sea levels were approximately 6 to 9 feet lower than present day, exposing a wider coastal zone. This environmental context, detailed in the study, allows researchers to pinpoint the age of the prints to around 13,000 years ago. The footprints were found impressed into a 13,000-year-old paleosol beneath beach sands at archaeological site EjTa-4.
The arrangement of the footprints suggests more than just a simple passage across the beach. Instead of a linear trail, the prints are clustered, with several positioned side-by-side and facing inland. “Most of the footprints face inland… and they may represent a place where people were disembarking from watercraft before moving to a drier area,” McLaren stated. Some heel marks display evidence of dragging, indicating the individuals were walking barefoot on wet, soft mud.
The sizes of the footprints suggest the presence of individuals roughly equivalent to a woman’s size 8-9 shoe, a junior’s size 8, and a smaller adult. According to McLaren, “Primarily the three different sizes of footprints found conjures up the image of a nuclear family or small group of people using the area.”
The discovery contributes to the ongoing debate surrounding the initial peopling of the Americas. Even as the prevailing theory centers on migration across a land bridge from Asia, increasing evidence supports the possibility that early populations also utilized coastal routes. The presence of footprints suggests reliance on watercraft for navigation and settlement along the Pacific coastline.
Neil Thomas Roach, a Harvard University researcher not involved in the study, noted the find reveals an “intensive usage of this coastline environment” not previously documented in such detail. “I think this study raises more questions than it answers, which is a good thing,” Roach said. “Only with further study and excavation of these shoreline surfaces will we fully understand how many track makers were present, what they were doing on these landscapes, and how important shoreline environments were to their survival.”
Researchers are continuing fieldwork at the site, documenting and extracting sediment from a structured excavation grid. Further analysis is planned to determine the full extent of the footprint site and to gather additional data about the people who left their mark on the shores of Calvert Island.
