Fifteen trial trenches were excavated to inform proposed residential development on land off Barbers Drove, Crowland. The trenches were targeted to investigate a number of geophysical anomalies recorded by a prior magnetometry survey (see ELI3174). The trenching confirmed the presence of a series of east to west aligned parallel linear features, thought to represent medieval or pre-Enclosure drainage ditches, but resolved all of the other previously recorded magnetic anomalies as being of modern origin. The trenching also revealed a series of natural marine silts, overlain by prehistoric peat deposits across much of the site, and cut by a number of former palaeochannels. Environmental samples were taken from many of these deposits (see ELI12812). {1}{2}
