In the deep south

Today we reached the southern pointy bit (that is a technical term) of the Theatre field which results in a lovely tidy survey with a nice straight edge (at 513200 in case anyone cares!).

It is a satisfyingly large slice of the area we have to cover, but a painfully long walk back to the Gorhambury drive were the cars are parked and our portaloo!  Zooming into the area a bit, we can see there are fewer clear stone buildings than to the north.

There is one stone building just on the northern side of the ‘1955 ditch’, but other than that all we can see (and I emphasise “we can see”) are a number of ditches and probable pits.

The GPR extended the block which contained “the house on the hill” and picked up another nice building near the eastern edge of the survey.

The topmost slice in the image shows hints of the walls but is still essentially the top surface.  The big change three-quarters of the way across is where it rained overnight between days 9 and 10!  The second slice shows “the house on the hill” very nicely, and some features in the building to the east, but not so clearly.  The building to the east is down slope and thus buried in a greater depth of soil than the building to the west.  The final slice shows the building to the east very nicely but we are starting to loose the details in the building to the west.  When I have more time, we should be able to produce more detailed and clearer images.

The next two images show the location of the block overlain on the mag for comparison.

Tomorrow we start the long trek north once more.
