Archaeological Rush to Preserve 2,000-Year-Old Dog Walker's Footprints on Scottish Beach

Archaeologists are racing against time to preserve 2,000-year-old footprints discovered by dog walkers on a Scottish beach, after they began shifting in the sand at Lunan Bay in Angus, Scotland. The site is believed to be one of the oldest known examples of ancient human migration routes. A team of archaeologists has been working around the clock to carefully excavate and document the footprints before they are lost forever.
