Archive for the excavation of fifteen trial trenches and a programme of environmental sampling, conducted 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), and recorded a series of east to west aligned parallel linear features, thought to represent medieval or pre-Enclosure drainage ditches. 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. It was from these various deposits that the environmental samples were taken, and analysis of which showed a gradual progression of the site from a lower intertidal zone to tidal salt marshes to fresh water peat beds, subject to periodic inundation.
