Two days work

A quick posting to show the results from yesterday and today. Firstly, the magnetometry:

As can be seen, we are slowly getting close to completing this huge field.  Looking in more detail at the area we have surveyed over the last two days:

As can be seen, we have finally “turned the corner” and completed the survey of this section of the “1955 ditch”.  It is interesting to see that the corner seems a bit odd.  Was it filled in quickly?  Was it never completed?  There certainly seems to be a bit of a break in it.  Outside the ditch to the north is… well, not a lot.  This area is, however, quite a steep slope down into the valley in which the infamous “sinuous ditch” runs.  Unfortunately for the mag team, we had another sensor freeze and we will have to re-do part of one grid square just about on the steepest slope.

The earth resistance survey has been progressing slowly.  The hot weather has led to dry conditions in the top few centimeters making it hard to survey with the res.  We have, however, started to pick up the temple very clearly.

Lastly, the GPR results.  I have only processed yesterday’s survey so far, but the team have found another couple of buildings:

GPR survey from day 25 (top block), third slice (12.5 to 15.5 ns).

The plough soil up against Gorhambury Drive is probably quite deep judging by the depth of the road so I am surprised we are still picking-up buildings so close to it.

That is all for tonight.  Many thanks to everyone who toiled in the hot sunshine.  It is most appreciated.
