University of Birmingham. Published July 23, 2010 The discovery,
made completely without digging, suggests that now solitary
Stonehenge may have been surrounded by "satellite Stonehenges,"
archaeologists say. "This finding is remarkable," said survey-
team leader Vince Gaffney, an archaeologist the University of
Birmingham in the U.K. "It will completely change the way we
think about the landscape around Stonehenge." Using the latest
geophysical imaging technology, Gaffney's team captured digital
impressions of the now buried remains of the newfound henge
formation, just over half a mile (900 meters) from its world-
famous neighbor. Measuring 82 feet (25 meters) wide, the
circular feature had a segmented ditch dotted with 20 or so
large holes—suspected to have been postholes for a timber,
rather than stone, circle, the team says. (Also see "Wooden
