Archaeologists on Calvert Island in British Columbia have uncovered twelve human footprints that may be the oldest found in North America. The prints are at least 2,000 years old, but a piece of charcoal found in the first footprint yielded a radiocarbon date of 13,200 years before present. It's like taking a step back in time.
