How often do you visit a rock-art site armed only with binoculars? You do at Bangudae, on South Korea's east coast, and with good reason, as Brian Fagan discovered on a recent trip to the region.

During the most recent Ice Age, researchers believe there was a "lost land bridge" between Wales and Ireland.

Back in the early 2000’s I spent some time exploring the Prehistoric rock art of Allan Tofts on the North York Moors. Many of my images from that time have been lost. Here’s a few that I managed to salvage. On visiting the moor recently, I noticed that a number of these stones have disappeared beneath the peat. A few can still be found, the carvings can be quite subtle so are be seen when the sun is low and casting shadows.
