During the last few days the excavation has progressed, and we have made a large plan of the cupmarks on the rock art outcrop, to add to our photogrammetry and laser scan, so we have three ways of recording this surface, and later we’ll be able to compare and contrast…
We have also spent some time doing an ‘auger survey’ of the surrounding landscape, specifically looking at a paleo channel below the rock art outcrop and further afield.
Augering is the use of drill-like tools to take small samples or columns of sub-surface deposits. These are also known as ‘cores’ or ‘boreholes’. The advantage of hand augering is that it is fairly quick and easy to carry out, in comparison to more extensive excavation. It has been used here to test the depth of deposits, and to retrieve material for further analysis.
Today also saw our first media call, with HENO, a Welsh language magazine show coming along to interview Rhys Mwyn and me, to help promote the Archaeology Open Day on Saturday – it will be shown on Friday night’s show if anyone is interesting in watching!
