Wessex Archaeology was commissioned by Bloor Homes to carry out an archaeological trial trench evaluation on land off Morton Way, Thornbury,South Gloucestershire (centred on NGR 364384 191304).The evaluation consisted of 15 machine excavated trial trenches, comprising an approximate 4% sample of the site. No archaeological features or deposits were recorded within the 15 evaluation trenches. Natural features that broadly correspond with geophysical anomalies were identified within the base of the excavated trenches and have been interpreted as possible ice wedge/erosive channels (Trench 5) and combes (Trenches 2 - 4 and 12). A modern soakaway was identified in Trenches 1 and 2 which correspond to an area of strong geophysical response.
