Jonathan's Cave, with its rare trove of 1500-year-old rock art, risks being flooded by the sea or buried in a landslide. But rather than fight the elements researchers have opted to save the cave by putting the whole thing on the Internet. A team led by Joanna Hambly, an archaeologist at the University of St Andrews, UK, is using a series of laser and visual scanning techniques to recreate a virtual cave in minute detail. Starting last year, the team brought in a low-flying drone to shoot aerial footage of the outside of the cave and the surrounding land. Lasers then scanned the cave, both inside and out, to build a 3D model of the site on a millimeter-scale.
