West Midlands Regional Research Framework for Archaeology, Seminar 1: Jackson 1 Pits, Pots, Places and People: approaching the Neolithic at Wellington Quarry Robin Jackson Worcestershire Archaeological Service Rjackson@worcestershire.gov.uk Background Archaeological investigations by Worcestershire Archaeological Service have been undertaken since 1986 at Wellington Quarry, Herefordshire, on behalf of Lafarge Redland Aggregates Ltd. The quarry is located at NGR SO 508 479 and lies between the villages of Marden and Wellington, 7 kms north of Hereford. It is situated on the broad floodplain of the River Lugg, to the west of the river and adjacent to one of its tributaries, the Wellington Brook. Slight undulations in the modern pasture fields reflect former courses of the Lugg or the Wellington Brook. Approximately 52 ha of quarrying have been completed at the time of writing. Initial interest focussed on Romano-British structures and deposits, first recognised in 1986, which led to the site forming a major focus of an English Heritage funded project, the Hereford Valleys Survey. This carried out research into techniques for identifying and evaluating deeply alluviated sites (Dinn & Roseff 1992), alongside which research for a doctoral thesis examined the nature of the alluvium and associated palaeochannel (Roseff 1992). Limited programmes of salvage recording and interim reporting followed until 1996, when a detailed programme of salvage recording commenced, informed and directed by the PPG16 led planning process. Using the results and the lessons from Wellington, this paper explores: The nature of the palaeoenvironmental and alluvial sequence; The evidence for Neolithic and Beaker period activity recorded within this sequence; The character of this activity and its impact on the local environment; Its contribution to the wider understanding of patterns of earlier prehistoric activity in the region; The methodological and curatorial difficulties of approaching such sites. The evidence The alluvial sequence A working model for the development of deposits in the Lugg Valley has been established over the years. This indicates that the late Glacial Lugg basin was crossed by a pattern of braided streams, which laid down deep gravel beds (Terra Nova 2002). Gradually the Lugg rationalised into fewer channels and finally into a single channel which today runs east of the quarry. At least one major former channel and numerous smaller channels survived as sinuous depressions within the quarry. The deepest of these probably remained as seasonal streams and all were gradually filled by silt and clay during overbank flooding. West Midlands Regional Research Framework for Archaeology, Seminar 1: Jackson 2 Overbank flooding has deposited a significant accumulation of alluvium across the whole floodplain. Over a long period of time this has in some places raised the valley floor by over 2 metres. This alluvium comprises three basic units, although more complex deposits tend to be present over depressions in the underlying gravel. The different units of alluvium appear, however, to reflect simple stratigraphic variations resulting from a range of processes. These include differences in parent material, in the way and speed at which they were deposited, and in post-depositional processes. These have considerably affected the appearance and survival of alluvial and archaeological deposits as well as removing much of the associated stratigraphy. Consequently, it is only by understanding these processes that we can hope to understand the archaeological deposits contained within the sequence. Finally, quite different deposits occupying former channels occasionally interrupt the basic sequence. These are usually coarser and occasionally include pottery, bone and charcoal. Some contain waterlogged peat and organic rich deposits towards their base. These have been extensively sampled for environmental analysis. The palaeoenvironmental evidence Analysis and assessment of pollen from two monoliths taken from palaeochannels has produced evidence of environmental change in the valley floor. The first of these was taken from an early course of the River Lugg (dated c.14400-11700 cal BC; Brown & Hatton 2001) but it is the second which is of relevance to this paper. This was recovered from deposits in an early post-glacial course of the Lugg. Assessment of a pollen sample from this major palaeochannel (Greig 2002) has revealed the following sequence: Woodland at c.6800 BP (5000 BC) with alder carr in the valley base and oak, lime and elm beyond. At c.5000 BP (3000 BC), oak charcoal and the slight presence of cereal and plantain suggest first human impact, but in very wooded environment of lime, oak, elm and hazel. Local environment is of wetland with alder, hazel, elder, sloe and a range of herbs. Phases of clearance and increasing signs of arable farming follow but it is not until considerably later that there are signs of elm decline and then oak and lime with cereals, grasses and grassland indicators increasing. The sequence ends with alluvium filling the upper levels of the former channel. This can be broadly dated to the later first millennium AD. Along with waterlogged plant macrofossil remains, coleoptera and molluscan remains, analysis of this sample should provide a detailed model for the environmental history of the Lugg Valley from the Mesolithic onwards. The Early Neolithic pit group A group of 13 Neolithic pits provide the most important evidence for early human activity at the quarry (although a small quantity of Mesolithic material attests to earlier activity). The pits are all circular to sub-circular. They measure between 0.60 and 1.24 metres across and up to 0.50 metres deep, although some truncation may have occurred. The pits had steep sloping sides or were slightly ‘bag-shaped’. West Midlands Regional Research Framework for Archaeology, Seminar 1: Jackson 3 The associated pottery assemblage comprised nearly 1000 sherds, weighing almost 10 kg. The majority was present in two of the pits, with approximately 20 vessels in one and about 10 in the other. Three others also produced limited quantities. The pottery is in a quartz tempered fabric with variable quantities of temper present (Gibson 2002). Surface finish varies with some sherds having large angular quartz inclusions breaking the surface and readily visible. Others are, however, well-finished with burnished surfaces. The vessels represented are open and carinated bowls, occasionally with fluted rims. They are typical of the bowl traditions of the 4th millennium BC, which are widespread over Britain, Ireland and continental Europe. The pits rich in pottery also included broken quartz pebbles, some apparently burnt and crushed. These closely resembled the principal temper used. This raises the potential that pottery was manufactured at the site, a possibility supported by presence of three stone burnishers or smoothers. Ten pits contained flint with a total assemblage of 443 pieces and numerous unquantified spalls from sieved samples. Most of the flint was good quality material which, allied to a paucity of core preparation flakes, suggests that prepared cores might have been imported to the site (Bellamy 2002). Diagnostic retouched forms include leaf-shaped arrowheads, a serrated flake, scrapers and flake knives, which are consistent with the dating, provided by the pottery. The assemblage provides evidence of a range of activities including flint knapping, hunting, the preparation of foodstuffs and the working of other materials. Although conditions of preservation for animal bone were poor, cattle, pig and sheep or goat were represented in small quantities. Charred plant remains were also present, including hazelnut shells and a small quantity of cereal, which where identifiable was emmer wheat. Later Neolithic pits Further pits and associated features provide evidence of later Neolithic (associated with Peterborough ware) and Beaker period activity. The Peterborough ware was in a quartztempered fabric and represents two vessels, probably of the Mortlake substyle. Beaker and possibly earlier pottery has also been recovered as residual material in Late Bronze Age dumps in former channels/ponds. Funerary deposits A ring-ditch fragment was identified to the north of the Early Neolithic pit group. This had been machine truncated but a 7 metre length of the ditch survived. This produced a rim from a Fengate substyle vessel. This probably dates to c.3000 cal BC. Further potential ringditches were identified to the east and are also present to the north as cropmarks. The most significant burial is an intact Bell Beaker grave dating to c.2750-2500 BC (Harrison, Jackson & Napthan 1999). The grave contained a poorly-preserved crouched adult inhumation and had no signs of a ditch or barrow. Apart from a complete Maritime All-OverOrnamented Bell Beaker, the grave contained a tanged copper knife, a shale wristguard fragment, four barbed and tanged arrowheads, three arrowhead blanks, three flint knives, two triangular points or small daggers and four flint flakes. Different states of wear and completeness indicate that the items had different biographies and had been carefully selected either because of their resonance to the deceased or those who selected them. West Midlands Regional Research Framework for Archaeology, Seminar 1: Jackson 4 Spreads of Neolithic and Beaker material Aside from the pits and funerary features, a scatter of Neolithic and Beaker material including both barbed and tanged and leaf-shaped arrowheads, knives and scrapers, polished axe fragments and a pebble hammer have been recorded from alluvial deposits and as unstratified material. Pottery has also been recovered including some whipped cord maggot decorated sherds. These finds attest to widespread use during the early prehistoric period of virtually the whole of landscape covered by the quarry. The character and importance of the activity In terms of understanding funerary monuments, Wellington adds little to the regional picture. Although the Beaker burial is one of wealthiest in region and indicates the importance of the site to the prehistoric population, it is an isolated find while the ring-ditches are poorly preserved and no burials have been recovered. More important evidence lies in the Early Neolithic pit group, the associated palaeoenvironmental assemblage, and the longevity and changing use of the landscape represented. A number of areas of regional research potential can be identified: 1. The Early Neolithic pits at Wellington provide one of the best examples of this type of site for the period. Pits, such as these, are encountered on sites with little or no other evidence of contemporary occupation or other activities. These features typically have single fills and varied patterns of apparently carefully selected cultural material (Thomas 1999, 64). These provide a primary form of evidence for settlement representing temporary camps or seasonal bases at which structures were only flimsily constructed and at which repeated occupations may have occurred (Whittle 1999, 64). 2. Wellington provides an example of a place that appears to have developed a domestic or social significance for the local population during the Neolithic, thus attracting episodes of occupation over a long period of time. Unlike contemporary ceremonial sites, there was no obvious attempt at formalising space or inscribing a presence on the landscape at such sites. However, as a repeatedly used space they appear to have developed symbolic importance as a place, either as a result of attachment of memories, usefulness, superstition or even observation of the traces of previous occupants. 3. The material assemblages provide an opportunity to examine a significant assemblage of cultural material of this date in the region. They also provide an opportunity to consider local systems of belief and practice through study of relatively large and securely stratified assemblages of material. Some pits contain apparently nothing (although of course organic remains may have been present), yet other seemingly similar features include large quantities of artefacts. Such selective depositional practice can be viewed as a means of using the material world to create a specific meaning for a place or event and thus perhaps formalise a connection between people and place or even transform the way it was perceived (Thomas 1999, 87, 224). Another possibility is that the burial or planting of material culture in disturbed ground reflects an attempt to ensure the continuation of supply of resources (Gibson 1999). In other words these items might have been perceived as having lifecycles similar to plants. Consequently, these had to be maintained and encouraged through returning them to the earth from which they derived in the hope of ‘renewal, regeneration and return’ (Edmonds 1999, 29). 4. Wellington provides an opportunity for examining issues of continuity or discontinuity, West Midlands Regional Research Framework for Archaeology, Seminar 1: Jackson 5 through comparison with earlier sites and practices. A strong sense of continuity from the Mesolithic can be suggested, for instance in the transient nature of occupation and repeated possibly symbolic use of certain sites (Mithen 1999, 51; Whittle 1999, 59). Furthermore, Mesolithic sites with pits and tree-throws containing material culture are common and certain elements of deliberate deposition and selection might be suggested. This may indicate that, although Neolithic activity often occurs in apparently previously unused areas and uses a more extensive and complex repertoire of material, their use in some respects may reference earlier belief systems and practices. 5. Comparison may also be made with later sites. An increasing complexity in the range, patterns and manner of material deposition extends throughout the Neolithic. As well as reflecting a degree of continuity, analysis of artefactual and ecofactual assemblages from a range of sites has the potential to reveal how the use and deposition of material assemblages was modified and elaborated through time according to local conditions and strategies (Thomas 1999, 222). 6. The association of early prehistoric occupation deposits at Wellington with a palaeoenvironmental and alluvial sequence means that the site has high potential to reveal evidence for local economic strategies and resource exploitation. Evidence is also present for local and wider human impact on the landscape, for instance through episodes of woodland clearance and the introduction of cereals, the charred remains of which have been recorded in the Early Neolithic pit group. The regional context Locally, few sites have produced Neolithic pits and those identified are mostly of Middle to Late Neolithic date. Sites with Early Neolithic plain ware assemblages are rare, but include Warwick, Baginton, Sharpstones Hill and Bromfield, as well as recently discovered sites near Hereford (Keith Ray pers comm), and at Church Lawford Area ‘D’ and King’s Newnham Area ‘C’ in Warwickshire (Stuart Palmer pers comm). However, these assemblages and associated material are not of comparable size and range to that from Wellington (although Warwick, published only in interim form, has produced a large assemblage). The range and quantity of Early Neolithic material from Wellington is thus unparalleled in the West Midlands and has great importance for the study of regional material culture, strategies and practice, as well as for comparison with both Mesolithic and later Neolithic sites in the region. Charred cereals, collected plant foods and evidence of domesticates provide additional data on the use and availability of resources at the site. Associated palaeoenvironmental and alluvial sequences have the potential to provide significant information on the exploitation and adaptation of the wider environment. Since no comparable sequences have been recovered from the West Midlands, these considerably add to the regional research potential of the site. Wellington is also of importance for understanding wider patterns of Neolithic activity in the region, supporting evidence from other sites for trends in practice. At Moele Brace and Bromfield pit groups represent the first human activity identified. These have been interpreted as ‘the first marking out’ of sites which later assume importance as burial sites (Hughes and Buteux 1995). This initial inscription of a landscape can be seen at Wellington, where the site’s importance extends over several millennia, to include Beaker, Late Bronze Age, Iron Age, Romano-British and early medieval activity. The choice of location at a West Midlands Regional Research Framework for Archaeology, Seminar 1: Jackson 6 confluence is also echoed at Bromfield and other sites and may be significant. Within the region where Neolithic pits provide the earliest evidence of activity, as at Wellington, Meole Brace and Bromfield (as well as several sites in the Central Severn Valley), there is no evidence for the development of communal ceremonial or monumental complexes. Indeed there are very few such sites in the Central Severn Valley or the Herefordshire Basin as a whole. However, they are represented in adjacent upland areas and in the Avon Valley to the east where early pits often accompany or ‘mark out’ sites which develop as ceremonial complexes such as Barford. This pattern reflects that of the Upper Thames Valley (Hingley 1999) where clusters of monuments occur along the length of the river, particularly at confluences (Thomas 1999). Aerial photographic evidence suggests that this pattern can be extended into the area of the Worcestershire Avon but no further. This absence may reflect archaeological coverage or masking by alluvium. However, broad areas of gravel terrace are present and extensive aerial photographic coverage has produced many cropmark complexes (eg. Whimster 1987). Thus the paucity of evidence for early monument complexes may be a true phenomenon. One possibility is that there were different cultural groupings in the Central/Southern Severn Valley and Hereford Basin with their own diagnostic traditions. Alternatively, the pattern could reflect the use of valley floors as seasonal grazing areas by communities who also frequented the surrounding uplands where they constructed larger communal monuments. Methodology Sites such as Wellington are rarely encountered and are typically characterised by dispersed and sometimes deeply buried remains. As a result they pose important methodological challenges in terms of prospection, recording and analysis. Fieldwork approaches Evaluation techniques are particularly important since these provide the basic tool for identifying and protecting sites. A recent review of evaluation and sampling techniques considered 8 large area excavations. The one period represented on each was the earlier prehistoric, even though deposits of this date were not the ‘target’ of the excavations (Hill & Lacey 2001). From this several observations can be made: 1. Earlier prehistoric sites might be more common than is often assumed. 2. As highlighted by the survey, higher trenching sample levels than the commonly applied 2% should be used on to improve chances of detection of sites especially where dispersed and ephemeral remains were anticipated (Hey & Lacey 2001, 48-51). One suggested approach is the use of an initial 3-4 % sample with further problem-oriented investigation to follow (ibid, 51). For alluviated sites additional problems exist, since remains may be deeply buried. A number of techniques have been adopted at Wellington and other sites. These include: 1. Wide trenches should be encouraged to enable sufficient areas of deeply buried horizons to be examined and thereby improve chances of revealing deposits relating to early prehistoric human activity. 2. Trenching should be both preceded and supplemented by the use of borehole data, test West Midlands Regional Research Framework for Archaeology, Seminar 1: Jackson 7 pits, augering and geoarchaeological specialists to facilitate deposit modelling and assessment of potential areas of activity. On alluviated sites the need to comprehend the alluvial sequence has a number of implications for any mitigation strategies developed following evaluation (over and above those normally applied): 1. In areas of higher potential, an archaeologically-determined approach to overburden stripping should be adopted which provides alternating long sections and areas in plan. The areas revealed in plan provide ‘normal’ conditions for the identification and investigation of deposits while the long sections allow recording of the alluvial sequence. 2. The depth of stripping to reveal areas in plan may need to be varied, as the depths at which archaeological remains occur can vary widely across a valley floor. The process should be informed by the evidence from the long sections and the previous strip. Provision should be made for excavation to more than one plan horizon during any one strip since significant deposits may occur at different levels within one area. 3. Alluvium recording is specialised, usually requiring the availability of a geoarchaeologist on site. This is expensive and impractical in that few specialists are available and sites are often worked over many months each year. At Wellington, David Jordan of Terra Nova has worked with the field team to create a system for recording alluvial sequences and trained them to use it. In brief, the deposits revealed in section are drawn, and detailed alluvial profiles are recorded at regular intervals using specially designed pro-forma. Alongside a ‘traditional’ context-based stratigraphic record, these provide details of subtle variations in sediment structure, ped structure, staining, mottling, panning, coatings and evidence of rooting, cracking and worm action. Photographs, box samples and monoliths are taken to accompany the record. Periodic visits by the specialist team ensure that the system is being properly used and that atypical alluvial strata can be examined. This ensures that the resultant archive can be used to determine whether the boundaries of texture and colour relate to parent material, depositional, or post-depositional processes, rather than conventional archaeological interpretations of apparent stratigraphy. 4. Contingencies allow for the excavation and recording of any areas of important archaeological deposits revealed. Since these are often isolated and comprise small single filled features they can be relatively rapidly excavated with bulk sampling ensuring the maximum retrieval of artefacts and ecofacts. Post-fieldwork approaches There are also challenges in analysis and interpretation of early prehistoric deposits and associated cultural material. One example is the development of a detailed understanding of the biographies of artefacts, for instance through pottery residue analysis and flint microwear analysis. Dating is also important as the introduction and longevity of ceramic traditions can be variable between regions. Overall the lesson is that it is important that a wide range of techniques are used to analyse early prehistoric sites that produce high quality artefactual and ecofactual assemblages. Naturally this has implications for funding which need to be taken into account. However, the potential of such approaches has been demonstrated regionally at Walton Basin in Radnorshire (Gibson 1999). Here examination of Peterborough Ware and Grooved Ware assemblages has revealed different uses and ranges of activity associated with West Midlands Regional Research Framework for Archaeology, Seminar 1: Jackson 8 the different pottery styles, despite similar contexts of deposition. This implies that different social practices and strategies may have been employed in circumstances which otherwise appear similar. Management approaches Lastly, informed decisions are needed by archaeologists involved in the process of evaluation, investigation and protection of such sites. At Wellington, co-operation between Curator and Contractor has been a key factor in the development of appropriate strategies. Elsewhere, personal experience and anecdotal evidence suggest that problems arise from a poor understanding of the character, importance and potential of early prehistoric sites (especially those sites where funerary practices or major ceremonial features are not present). Whether this comes from Curators, Consultants or Contractors, it is clearly poor for the image of the profession, not to mention the proper management, protection or investigation of the archaeology, if there is conflicting understanding of the potential of a site.
