With a hive of activity happening in this area at the conclusion of season 2015, the South trenches looked to hit the ground running again in 2016. Trench 9 was re-opened once again, to finish off the investigations started in 2014, while two new trenches were established with one being for the purpose of resolving the archaeological questions that had risen from two previous trenches in the Southern area, and the other as part of an investigation into the other side of the wetland, on the dry ground. Trench 14, which was opened over Trench 8 (season 2013) and Trench 11 (2015 season) with the hope of establishing the relationship between in the stone mound found in T8 and the large timbers found in T11. The other trench opened in the south area, was Trench 15, which was opened in the second half of the season to establish the limit of archaeology in the southern area. Despite a horribly wet start to the season, we still managed to gather plenty of information about this area of the site from these trenches.

Unfortunately for us, season 2016 was not a nice one for Trench 9. After two years of weird and wonderful features and finds from the trench that lay on the edge of the wetland’s tidal area, this year, the weather won out. Despite getting the trench opened (with some changes in dimensions to accommodate the need to investigate specific features), cleaned and ready to be excavated again in the first week, the rains came and came and came, turning the trench into a pond, a lake and finally a dam. This meant that it was never plausible to excavate in dry conditions until the last fortnight of the season.
Trench 9 after the heavy rains
With the end of the 2015 season providing us with a wealth of things to look at in Trench 9 this year, sadly, many of them could not be investigated. The north-western corner stayed under water the entire time, meaning our brushwood platform and Neolithic post-hole settings could not be looked at further. Instead we targeted central area where we had the sweat lodge, hearth and Neolithic plank, with the latter being the first area of investigation. With the new extension of the trench, 1m further into the wetland, we were hoping to find the plank extending further, with more stake-holes running parallel with it to provide hope on our walk-way theory. Instead, the wood only extended a further 20cm with a multitude of stake-hole present at its extent, but with no real alignment in their arrangement. We only had time to photograph, plan and record these new findings before the season finished, but we no longer believe the plank to be part of a walkway and so further investigation may be undertaken in this area in the future.
Another feature we looked at this season was our prehistoric sweat lodge. Once cleaned and photographed again, a quarter-section of the circular feature was excavated down to natural, with the hope of finding floor deposits and artefactual material associated with the feature on the way down. Sadly, it was to no avail, and so the only dating we can do for this feature is based on its position in the stratigraphy. The Mesolithic hearth, however, yielded some further evidence of its purpose and age, with an additional two pieces of worked chert discovered during an environmental sampling of the feature. The hearth was not found to be very deep, although the weather in the early part of the season had scoured away a significant amount of the original feature, despite our best efforts to minimise the rain’s impact, but measured ~1m in diameter. We still believe that the hearth and the sweat lodge are contemporary with each other as they both sit on the same level in the stratigraphic sequence of the trench, but as for the other areas of interest in Trench 9, we can’t make further comments as we simply didn’t get a chance to investigate them this season due to the weather conditions.

It is still unclear as to what will happen with Trench 9 in the future at the Kaims. In terms of evaluating what archaeology was present in this area of the wetland margins, we have done so with aplomb. There is still firm belief that the area where Trench 9 lies, may be connected to the area where the new Trench 14 is located, and so it may be opened for one final time to conduct a large evaluation between the two trenches.

When we last visited Trench 14, we had a couple of goals in mind. One goal was to expand the quarter section to provide a fresh understanding of the stratigraphic sequence of the stone mound, brushwood platform and peat layer. Our other goal was to expand north, to an area that we expected Trench 11’s paleochannel to continue through. We accomplished both goals, first expanding the quarter section and excavating down to a depth of over one metre below the surface, into the peat layer. We removed the layer of brushwood and we were very excited to discover large timber “planks” lying parallel to each other. This discovery was made the second to last week of the season, so great care was taken to record the planks in detail: photographs, plans and Timber Recording sheets in preparation for next year’s field season. We hope to continue in T14 and to discover if there are more timber planks underneath the stone mound and in the surrounding area.

As our attention turned to expanding into the expected paleochannel area, we were happy to discover that it does indeed continue and the layers of sand in T14 are similar to the layers of sand found in T11 last year. Minimal excavation was carried out on the channel, but hopefully next year more excavations can be conducted. One interesting discovery made during excavation of the quarter section (an area abutting where we expected to find the paleochannel) was a layer of sand different than what was found in the feature last year. This sand had a definitive reddish hue to it, whereas the sand found last year in T11 had a yellowish-brown hue. The reddish sand was recorded thoroughly at the end of this field season and will probably come into play next year as excavations continue in this exciting area of the Bradford Kaims.

Situated alongside Winlaw Burn, and to the very west of our area of investigation in Embleton’s Bog, we opened up Trench 15. The purpose of this trench was to establish whether we had any archaeological evidence as far west of our site as this, and to investigate an anomaly on a LIDAR survey of the Kaims area. Being so close to the burn, and with the knowledge that the burn was constantly cleaned out during the Victorian period, we quickly determined that the anomaly was just a large dump of upcast from the this. Some very modern finds were also evidence of this. This still didn’t answer our question of archaeological limit, and so we carried down further, hoping to find the same prehistoric ground surface that has been found across the site in Trenches 7, 9, 42 and 55.
Despite several sterile layers of clay in the 2m x 1m trench, we finally reached what we believed to be our target surface ~1m below the top of the trench. Although no features in this trench, we did manage to find a solitary piece of worked flint at the very bottom of our sequence, indicating that we do indeed have evidence of human occupation as far west as this on our site. We may come back to this area in future seasons to search for further archaeological evidence, but for now we need to keep searching for the western limit of archaeological potential at the Bradford Kaims.

On behalf of myself, Becky Rutherford (Trench 14 Supervisor), Charlie Kerwin (Assistant Supervisor) and Ian Boyd (Assistant Supervisor) we would like to thank all the staff, students and volunteers that have worked with us in the 2016 season. Without your eagerness to listen and learn about archaeology, and your enthusiasm to help us reach our research goals, we would not have been able to learn as much as we did about this area of the Bradford Kaims this year. Thank you to all, and we hope to see you again next year.
