MESOLITHIC OCCUPATION AT BOULDNOR CLIFF AND THE SUBMERGED PREHISTORIC LANDSCAPES OF THE SOLENT eds G Momber, D Tomalin, R Scaife, J Satchell and J Gillespie. CBA Research Report 164, 2011. 222 pp, 164 illus include col. ISBN 9781902771847, pb £25 This report summarises long term, and ongoing, research into a very valuable Mesolithic landscape in Southern England. This research, however, is of a very unusual kind in a British context, as the Mesolithic landscape in question is located c. 11 metres beneath the surface of the western Solent at the base of an eroding cliff of peat (Bouldnor Cliff, with archaeological sites coded as BC-II and BC-V). These sites were inundated by the sea some 8000 years ago, and became well preserved until the evolution of the open marine conditions that are now actively causing submarine erosion (see below for detail). Archaeological materials are found in association with the landscapes, with some, at least, resulting from "...the first known Mesolithic archaeological excavation by a member of the lobster community" (p13). These disturbed artefacts, however, facilitated the discovery of in site archaeological materials – following the eviction of the lobsters. The methodological and infrastructural challenges involved in this kind of archaeology are extensive, and the rewards can be great; high quality preservation, especially in terms of the organic artefacts often absent from our dry land sites, can provide dramatic insights into the past (for a recent Danish Mesolithic example see Andersen 2009). There is also, however, a risk with wetland archaeology of all kinds: that we allow the quality of the preservation to overshadow the real significance of the material recovered in terms of how we understand human lives (Van der Noort & O Sullivan 2006). This can be further complicated by the labour intensive character of underwater archaeology – described by Benjamin (2010, 254) as “the most technically remarkable fieldwork”– and the justifiable pride of those involved in the work itself; especially in a situation where the methodological challenges are not widely recognised. The 2011 report seeks to give a background to the research to date and tackle both site specific and broader questions – with the latter aiming to look at both ‘human occupation’ and ‘geomorphological processes’ (see p xxv). This review will consider the book against this aims. The history of the project is interesting and there are lessons to be learnt from it. From the mid 1980s local fishermen began reporting finds of lithics from amongst oyster dredges and developing collaboration between the research team and fishermen has clearly been very important. Unfortunately, there is also a sense that the archaeological community may have missed the boat: fisherman Mike Jones, for example, comments on the amounts of material found when licensed trawling began in the region: "You should have been here then, Nipper, before us lads stirred it all up and scattered it all in a litter for you”. The authors describe the quantities of archaeological material found at that time as ‘astonishing’ (p3). The development of the research at Bouldnor owes much to the early involvement of Isle of Wight archaeologists in maritime and submarine archaeology, and in part, reads as a history of how funding opportunities for projects fade in and out of focus: in the 1980s, for example, the Isle of Wight Maritime Heritage Project with funding from the Manpower Services Commission had employed 24 people, leading to the first maritime SMR. Changes to national funding led to the collapse of Manpower Services Commission, and a reinvention as the Isle of Wight Trust for Maritime Archaeology and the development of the Hampshire and Wight Trust for Maritime Archaeology. The diversity of funding obtained (see the acknowledgements, p.xviii) and the longevity of the research is testimony to very creative fund raising abilities. The energy expended and the skills gained over time in this aspect of the project must have been considerable. The unusual context of the archaeology raised methodological challenges, and these are detailed in the report. The coordinators of the project acknowledge the high learning curve that they embarked upon and hope that documenting this is of wider benefit. "The project has provided the opportunity to develop the skills of those involved who were not familiar with submerged prehistoric landscape material; in this way the site is also contributing to an increasing capacity to recognise and investigate such sites in the future." (p. xix). The challenges of working underwater are considerable (see p. 14-16, but passim) and include only having an hour at a time on site, having very poor visibility (meaning that you can only see very small amounts of the site at any one time) managing air supplies whilst moving materials in and out of the water, and many more. Samples recovered from the sites include long cores and a variety of box samples recovered in specially designed boxes. These were subject to a variety of palaeoecological analyses: including pollen, diatoms, foraminfera, micromorphology, dendrochonology and the examination of plant, insect and fish remains. Archaeological analyses of wood and lithic remains were also carried out. These allow for some very detailed reconstructions of the palaeoevironment of the landscapes as a whole. The overall reconstruction of the palaeogeography of the Solent is dramatic. Momber and colleagues suggest an unfamiliar landscape, where the Solent forms a dry land basin linking the Isle of Wight and Hampshire and drained by N-S trending rivers that run through the western Solent basin and across the west of Wight on the line of the Lymington River and Western Yar. This leaves the Solent as a quiet, low energy environment at the time of Mesolithic occupation (c 6000 BC). Rising sea level leads to silting up and slow accumulation of sediment in the basin. This low energy environment is key to the nature of the preservation. These depositional landscapes vary in age according to the location of the site, and the interplay of regional sea level and local processes. Mesolithic landscapes are not the only ones preserved, although they have been the focus of the archaeological investigations. It is argued that the basin was breached from the east at c 5000 BC and then, more recently, from the west. This leads to a change from a depositional environment burying the archaeological materials, to an erosive one that is revealing and exposing them. A general model of geomorphological sequence is presented (p118): dryland, river bars or interfluves; increased wetness leading to peat formation; rapid sea level change leading to freshwater fen; finally full salt-marsh/mud-flats. The site specific sequences capture aspects of this broader model. BC-II, for example, is argued to have been a sand bar within a river system, its surface possibly stabilised by vegetation, in a pine woodland with oak and hazel. There is little evidence of erosion before peat formation where the surface is argued to be ‘pristine’ (p.37). It is proposed that the site is located right at the water’s edge, in a carr environment. The palaeoenvironmental work, supported by a robust radiocarbon framework, provides a strong model for landscape change over time in the region, and its development with future research will be very interesting. The book’s principal aim to present the geomorphological processes active in the area is therefore generally successful. But, what of the archaeology? Yes, the sites are remarkable for their location and some of the materials are impressive, but truth be told, the sites (as opposed to their materials and location) are not stunning in terms of what has been found so far. The archaeological materials appear in a number of different forms. Lithics were found in primary and secondary contexts. This includes concentrations of burnt small pebble flint, seemingly parts of pits, and presumably playing some role in a pyro-technology of some kind. Wood was recovered from BC-II and BC-V, and includes some dramatic artefacts: a tangentially split plank is considered to be ‘too massive for domestic application’ (p89) and is postulated to have been part of a boat. This plank is argued to push back the application of tangential splitting 2000 years from the Neolithic. A range of other wood working debris is present as well as evidence for coppicing using chopping and tearing techniques. The variety of wood present at BC-V, including both round wood and planks, leads to the suggestion that a 'substantial Mesolithic structure may have once stood in this location' (p. 81) although further work is required to detail this. One timber recovered from BC-V included an embedded burnt flint flake. Remarkably, some ‘prepared fibres’ were recovered from BC-V. Even more remarkably, apart from two photographs no further mention is made of this material – which is, to my knowledge, the first prepared fibre from the Mesolithic of Britain. Given that string manufacture was most likely a basic and enormously time consuming task for Mesolithic populations, it is a shame that so little is made of this find: what materials were used? What techniques? Some of the materials discovered, are therefore interesting, but the very small areas excavated, mean that the sites are hard to interpret. The report discusses the ways in these site locations highlight again the possibility that the Mesolithic of this area is "near-coast, nearcreek, rivermouth", but the discussion doesn't go very far. Tomalin’s call to integrate French typologies and industries to understanding this material 'sous Manche' (p. 159-160), is well made, but his attempt to place the site in context has a slightly scattergun approach to the recent literature. The attempts to discuss sedentism and the place of these sites in the wider archaeological landscape are simply too thin; at present we don’t have the data to understand how these sites fit. That isn’t the fault of the work at Bouldnor, it is simply the state of knowledge of these sites at present. Much more problematic is their argument that the plank working, and a single high quality tranchet axe indicate a level of craft skill not known in the Mesolithic of Britain, but not seen again until the Neolithic. These people with these technologies are therefore argued to have migrated out of Britain in the context of rising sea levels or simply to have lost or forgotten the skills (p. 174). We do not need to invoke a Mesolithic brain drain to explain this data. There is simply not sufficient data on Mesolithic and Neolithic woodworking to sustain this argument. The submerged landscapes of the Solent are therefore demonstrably very important. They provide high quality data on sea level change over time, not just in the Mesolithic, and contain potentially very valuable archaeological materials. Momber and colleagues argue that there is an urgent need to protect this nationally, and possibly internationally, important landscape (p 167). The threats are substantial: a major shift from depositional to erosive conditions, some threat from lobster fishing and the impacts of the burrowing and boring activities of lobsters, piddocks and gribbles (168ff). Little is known about the impact of these species on archaeological remains, although the incursion of 'more damaging gribble species' (p 170) into UK waters is noted as a concern. Assessment of risk, and development of management strategies is a key challenge for the future. The remarkable work presented in this volume, conducted over so many years, raises many possibilities and is highly commendable. However, the final report does suffer from some comparatively minor problems which could have been resolved by a firmer editorial hand and would have improved the final product significantly. There is repetition between sections throughout, and in places, details of context numbers are hard to follow (and numbers are not always presented on drawings). It is sometimes hard to work out exactly where things are: BC-V ‘Trench 2’ is shown on Fig 4.31, but the precise location of this in comparison to previous excavations (Fig 4.27) is not shown. The monoliths sampled from BC-II are presented in Figure 3.18 and following, but some samples are given mOD, others mm, others cm, and it is not easy to correlate all data. The discussion of the lithics is very confusing in its totals (especially of ‘tools’) and the illustrations miss key technical details (e.g. direction of percussion). Some pictures throughout the report are rather pixellated (and these problems were not caused by poor underwater conditions). These are minor problems, but do detract from the report as a whole and make it harder to interrogate the data that has been so painstakingly generated. The conclusion of the report highlights that “(t)he project has now reached a stage where investigators know what they are looking for and the potential of what they may find on the sea bed” (p.172). This report clearly highlights aspects of this potential, and the challenges the project team will face in furthering our knowledge of these important landscapes. With appropriate support, the submerged landscapes of the Solent have much to reveal about past human lives. At present, however, the archaeological discussions of the submerged landscapes are weaker than the palaeoecological ones, and the models of human occupation not as well developed as the geomorphological models. In terms of the archaeology, small pieces of data are being placed within more-or-less familiar interpretative frameworks. This is not the fault of the project – the considerable methodological challenges and the small areas excavated, means that little can be said about forms of past occupation at present. But the potential is clearly there for high quality data that can be wholly transformative. This is the real potential of wetland and underwater sites, to show us a new kind of archaeology of periods that seem familiar. References Andersen, S. H. 2009.
