New features within the henge at Avebury, Wiltshire: aerial and geophysical evidence

Abstract

The hot and dry summer of 1995 once again proved the value and cost-effectiveness of aerial survey. Numerous parchmarks were a product of the dry conditions throughout England, but especially in chalk grassland, and they revealed important new archaeological information. A parchmark within the great Neolithic henge at Avebury identifies a new subterranean feature, confirmed by geophysical survey, which fills in further details of the Avebury enclosure.
