Anyone new to this blog or geophysics in archaeology is recommended to read the material on the “Geophysical survey in archaeology” page.
Just a quick update as week 3 will be starting in about eleven hours and I’d like some sleep!
The GPR crew on day 10 completed three areas of “sawtooth”. Well done all for putting up with such an annoying, fiddly job, but it does look good along the edge of the survey. It took a bit of setting-up, processing-wise, but all was well. Sadly, not much showing (Figure 1).
Starting from tomorrow, the crew will be working their way slowly southwards, back up the hill. The downside is the hill, the upside is that they will be covering areas which clearly have buildings in them!
The earth resistance meter, operated by myself and Ellen, managed a modest two grids once we had set-up the other two machines. The results were good, however, and clearly show many of the details of this building in the top-corner of the Theatre field. The next three images show the mag, GPR and earth resistance results for this area.
Although the GPR data appears very clear, the Earth Resistance and mag data appear to show more walls between the main range and the road. There is a suggestion, also, that the “corridor” to the SW of the main range is in fact another phase. It would be odd for a corridor to have subdivisions. Plenty of room for debate over the details of this building.
Many thanks to all for your excellent work in the first two weeks.
