The site chosen for this intervention is a small tourist resort called Parkgate on the edge of the Dee Estuary. The unique characteristic of the land is the surrounding salt marsh which covers the expanse (80%) of the estuary today, but this has not always been the case. The estuary owes its origins to the passage of glacial ice southeast from the Irish sea, successive ice ages eroding the riverbed and surrounding landscape eventually derived sands and gravel forming both silt and mud.
