Protective fencing, surveillance cameras, and a laser-scanning project are some of the measures being put into place to protect Tutuveni, a Hopi rock art site in northern Arizona. “They would stop at Tutuveni and camp there, and they would peck their clan symbols on those rocks to mark their participation in that pilgrimage.

Underwater archaeologists from the Woods Hole Oceanographic Institution and Greece's Ephorate of Underwater Antiquities in Athens are using an autonomous diving robot to search for shipwrecks from the Age of the Minoans, more than 3,000 years ago.

So if we can find these ancient wrecks, we get a much clearer view of the very dim past," said Brendan Foley of Woods Hole.

St. Augustine's City Commission has passed a resolution urging residents to protect the city's cultural heritage from exploitation, in the wake of a proposed television show about digging up artifacts in local backyards.

A new remote-sensing technology, called the fluxgate magnetometer, has been used to examine one of Ohio's earthworks. The fluxgate magnetometer measures variations in the magnetic properties of soil, and was used to create an image of the Shriver Circle, which can no longer be seen on the ground.
