The new Trench S (shown shaded in red) was chosen because it overlies some interesting areas on the geophysics resistivity scan (shown as grey blobs) and is also expected to intersect the boundary ditch found before, (shown as a magenta line). It is 5 metres wide, 20 metres long and aligned north-south. Previous trenches are shown as yellow shapes and test pits as white squares.
Below is an interactive view of Trench 'S' - the brighter green area is the drone image. You can zoom in or out using your mousewheel or the + and - buttons below, and move the visible area around by clicking and dragging with your mouse.
