Day 18: The devil is in the detail

Rossnaree excavation Trench 4

Eimear backfills Trench 4

Today, a very dramatic occurrence took place – Trench 4 disappeared. Seriously, we had completed all the necessary work in that trench and yesterday, Kieran had started to backfill. Today, this job was completed in fine style by Kieran, Eimear, Niamh and Darren. We were even able to replace the sods back on the top. In a few weeks, it will be like we weren’t there at all. It is a bit sore having to fill in after so much slow painstaking work, but that is the name of the game in research archaeology.

Some very serious work was done in Trench 1 today by a very dedicated group of individuals. The first job was done by Louise who had yesterday discovered the pit-like feature at the south side of the trench. She drew a quick section of the feature and a plan as well. Once this was done, it was possible to start excavating again and although it had been decided not to excavate the full extent of the trench in order to save time, they went ahead and took out the remaining layers anyway. A fantastic piece of work. At this stage the final jobs to be done here are to draw the sections and take the samples. By the afternoon, Kim and Louise were setting up to start this so by tomorrow lunch time we should be ready to take samples. Things are moving very quickly!

Meanwhile in Trench 1 Matt and Darren started off the morning cleaning up the lower portions of the feature they had uncovered yesterday. They were preparing for record photographs and also for planning and drawing the section. The feature itself is interesting because it seems to be at a lower level than the wall and thus is earlier in date. It seems to have functioned as a revetting feature which held the slope in place. The slope is composed of quite loose gravels and this may have caused problems for the inhabitants of the site who wanted a more stable slope. As I mentioned yesterday, there seem to be similar features peeping out from the grass in the slope further along from the trenches where we are digging. This cleaning was completed by mid-morning, after which Darren went to Trench 4 and Matt got going setting up for drawing the plan. While they were cleaning down onto this final level, a number of very interesting finds came up which throw a lot of light on the date of the activity in this area. Almost directly where the wall feature made of large cobbles had stood within the bank, they found a portion of a double-sided comb, possibly made of antler. This is little bigger than my thumbnail but is nonetheless very significant. Finds like these typically date to the eighth century AD or later (as far as I know – I’ll have to check this) and it tells us that the bank/wall (and probably the ditch beside it as well) must date to this time or a little bit later. This is clear dating evidence for the feature from excavation and means we don’t have to wait months for radiocarbon dating in order to find out what date this activity was.

A couple of other finds from this general period came up within hours – a small copper-alloy strap and a fragment of an iron vessel. Sometimes this is the way things work out in archaeology – you don’t get the crucial finds until almost the last minute. in spite of so much flint from these layers, it is now clear that the feature is Early Medieval. The flint was probably on site already and was incorporated into refuse material used by the Early Medieval occupants of the site and there is still no doubt that the site was intensively used in Neolithic times. We now also know that it was also used intensively in Early Medieval times as well. We have another multi-period site, a bit like how the site at Knowth across the river was used. The big questions now are are the other banks and ditches the same date and where are the structures that were used in prehistoric times.
