The antepenultimate day

“Antepenultimate” is my second favourite word. At least I get more use of it than I do of my favourite word, “defenestrate”. I used to defenestrate my Christmas tree until I moved and now I can only deport it. Anyway, enough of this nonsense.

Today the mag re-did a few problematic blocks of data before moving on the survey a batch of new grids.  Here is the overall plan.

I think we should all be very pleased with the progress we have made.  Looking at the new area in more detail.

The large ditch which runs from the SW to the NE of the westernmost part of the survey is the return leg of our old friend, the 1955 ditch.  It looks like the northern part of this feature has been substantially backfilled with non-magnetic material as it is only visible faintly.  The sinuous ditch clearly crosses the 1955 ditch  and heads west up the shallow valley.  At least we can be sure now that the sinuous ditch post-dates the 1955 ditch.  Part of the western part of the sinuous ditch was found in the 2000 English Heritage survey.  The line of pits which appears to join to the thinner NW-SE ditch could be all one long linear feature.  This area may not have the big stone buildings found in the central part of the town, but it still asks a great many questions.

The GPR has now covered quite a large area.

Today they covered another 80x40m block to the south of the “uber magnetic” building.

We picked up quite a bit more of the building which was in the SE corner of yesterday’s block, as well as this missing corner of the corridor building to the SE.  The road does show, but not very clearly in the time slices.  There is also quite a solid area in the western part of today’s block; it maybe another building.

Tomorrow may be the last day if the weather forecast is accurate.  Fingers crossed that it isn’t!
