This week in Trench One we starting digging the test pit which we discussed in our last blog post. During excavations we identified a feature running east to west which showed as a dark patch running across the sondage with 4-5 vertically standing stones within it.
Also uncovered were at least two areas of burning which may possibly be related to the early timber palisade defence wall of the castle, but the evidence is currently inconclusive.
Excavations have revealed a grey patch, a pit dug on the robber trench, closer to the south edge of the trench, which is filled with rocks. It can be seen in section on the east wall of the test pit.
A second sondage was dug (measuring approximately 20x40cm and 60-70cm deep) in order to see if we could reach the bedrock and determine the depth of the natural boulder clay. This extent has not yet been reached.
The plan for the next couple of weeks is to identify 2-3 areas of interest to dig small sondages through to the bedrock. Digging out the whole trench would take far too long and too much effort when targeted depth investigations will suffice.
On a side note, the kiln has very nearly been completed and only one more layer remains within the kiln.
