Friday 15th April 2011

Our third excavation area was quickly completed as the natural orange clay of the area was very near the surface and there was relatively little archaeology here, where the archaeology is can often be seem starkly in the relationship between the orange clay and brown sandy silt.

The fourth area seems more problematic though as the hillwash deposits make it deep and the area is very large, so a dumper truck is required to speed the process of topsoil stripping up. Some of the archaeological features seem to appear closer to the the surface than others and so it is a little more tricky to decide exactly what level to strip to with the machine.

Towards the end of the day a hydraulic cable snapped in the excavator making a useful early start to the weekend!

    Water pressure is fully vaibarle. Generally speaking we keep the water pressure at around 2800 PSI (for clay soil). We use less pressure for softer ground. As you can see at the end of´╗┐ the video, the process of hydro excavation is non-destructive.
