In Trench 1600 the features within the roundhouse have become much clearer with the gully being clearly detected and a number of postholes within the line of the gully, probably indicating the structure of the walls. We have also found evidence of internal divisions within the building (below).

Excavation on the deep ditches of this odd-shaped enclosure are also nearly complete and show the many layers deposited in them after they went out of use. The picture below shows these layers in the ditch on the west side of the enclosure. There may be the slight traces of a bank revetment to the east of this ditch which can be seen as a stone scatter in the aerial shot above.

The curvi-linear ditch to the south of the roundhouse in this trench appears to be earlier than the roundhouse gully and there is increasing evidence that the roundhouse may pre-date the trapezoid enclosure, but more work is needed to clarify this. The gullies are very confusing as can be seen in the photo below as the digger is trying to work out what cuts what!

The students have also had a trial at resistance meter profiling. This method of geophysical survey allows segments of resistance data to be seen as slices. This is still very experimental, but may help in areas where we have blocks of high resistance that may be masking other activities (below). The readings are taken along the line of the grid at regular intervals to give a section of readings rather that the plan view.
