In yesterday’s blog post we mentioned that the site team had uncovered what appeared to be two pits. These pits were originally dug before the construction of the bank and ditch of Durrington Walls henge; therefore the material of the bank overlies these pits. The site team battled with the wind today with the goal of removing the remainder of the original Neolithic bank material.
The chalk band in the photo below shows one of the as yet unexcavated pits, which appears to be a pit with a ramp. This has shown the accuracy of the electrical resistivity tomography image from the Hidden Landscapes Team where the ‘saucepan-like’ image illustrates a pit and ramp very nicely.
You may also have noticed a small mound just at the top of the pit in the photograph. This has been interpreted as the original spoil from when the pit was first dug. As usual, we will need to excavate both the pit/ramp feature and the spoil heap to discover the real connection between the two.
21st century archaeological excavations in the Stonehenge Landscape bring with them a large amount of technology. Throughout the blog we will introduce a few different technological components that are important to the work being carried out at Durrington Walls henge over the next 2 weeks.
Adam Stanford of Aerial Cam (photo below) has been taking a whole sequence of photographs of the trench at Durrington. All of these images overlap creating a series of points within the trench. His software can then map these points across the entire trench and everything in it.
But it goes further – the software can then increase the number of points, the results of which can rival the accuracy of laser scanning. These points are then joined together to form a solid model, all without the colour and texture of a photograph (which can sometimes be a distraction).
The photographs can then be incorporated in order to see the different colours of the archaeological features and different soil types. The result in Adam’s words is “a photorealistic, textured, very accurate model of the whole thing”.
