How ground-penetrating radar has transformed archaeology

Jarrod Burks explains how radar technology has changed the way archaeologists dig in the dirt.

“Instead of throwing a dart into the middle of 40 acres, this accurately says ‘Here’s a bulls-eye,’ ” said Rick Perkins, chief ranger at the Hopewell Cultural National Park.

Outside his office at Ohio Valley Archeology on Sinclair Road, Burks recently demonstrated the technology. He peered down at a screen on a radar machine that he slowly rolled over a stretch of blacktop.

A black arch appeared – a pipe, he said, about 3 feet below the surface.
