Day one at our excavations was probably similar to many other day ones in many other research oriented excavations. It started with a struggle of almost every participating volunteer to raise the (party) tent 🙂 which serves as one of our field establishments. Yes, that’s correct, as one, because we have two – there is namely a trailer at the site used as a computer-lab for working with photogrammetry. And we have already made our first (test) run with this method too. Photogrammetry is the science of making measurements from photographs, especially, for recovering the exact positions of surface points – and thanks to the professor Frands Herschend from Uppsala University volunteering at the excavations, the methods seems to work just perfectly for the purposes of our excavations. I was really thrilled seeing the first results! It really seems that using photogrammetry makes the presence of the total station at the site pretty much redundant. I’ll surely share some results with you later on.
The test-run with photogrammetry was, obviously, done in the trench that we have started digging – we have started with the trench at the site of the hall. In terms of actual digging, it might seem weird to some, but I have decided not just to remove the soil that has been disturbed by ploughing as is quite usual during many archaeological excavations because of finds in plough-layer not being in situ – archaeologists need to get below the plow zone to find in situ artefacts. We are investigating the plough-layer because, as indicated by metal-detector mapping at the site, finds outside of their “original” context at this site still have an interpretational value in order to understand the site. Thus, these 30-35 cm of upper layers of soil disturbed by ploughing are scanned on the chopping/sorting table (= a table on which excavated soil is spread so that you can comb through it in search of objects of interest). The choice fell in favour of the chopping/sorting table instead of sieving as the site is characterised by the clay-soils and it just seemed to be easier to look through the soil on the table.
Quite so surprisingly, we had also our first media visit at the site 😀 resulting, among other things, in the footage you can see (after the 16 seconds long commercial) by following this link: https://aland24.solidtango.com/video/20140901-utgravningar
