Human-environment Interactions
during the Late Mesolithic of the
Cumbria Coastal Plain:The evidence from Eskmeals
Clive Bonsall
The Eskmeals area on the narrow coastal plain of southwest Cumbria contains one of the
richest concentrations of Late Mesolithic sites in north-west England.The Eskmeals sites
were discovered during fieldwalking by Jim and Peter Cherry in the 1960s and 1970s(Cherry & Cherry, 1986), and three of the sites were investigated by the present author
between 1974 and 1986 (Bonsall, 1981; Bonsall, et al., 1986, 1989). This paper
summarizes the results of the Eskmeals archaeological excavations and the associated
palaeoenvironmental work.
THE PHYSICALSETTING OF THE ESKMEALS SITES
The Eskmeals coastal foreland
TO south of the present estuary of the River Esk is an area of land
known as the Eskmeals foreland, which has been built up by coastal
processes during the Holocene (Fig. 2.1). The eastern margin of the
foreland is defined by a sharp break of slope that can be traced from the
River Esk north of Newbiggin to south of Stubb Place. To the landward glacial
sediments underlie an undulating topography of moderate relief that rises
steadily inland to over 200 m in a few kilometres. The coastal foreland itself is
formed by marine, estuarine and aeolian sediments resting on an eroded surface
of glacial deposits. A complex sequence of shingle ridges has been produced by
the dominant northwards-directed longshore movement of littoral sediment,and in the lee of the shingle ridges estuarine sediments have accumulated.
The aeolian deposits that have developed on the surface of the shingle

ridges comprise a seaward area of constructional dunes eastwards of which a large,
nearly flat, sand sheet has developed. A series of channels transect the glacial
deposits and apparently terminate at the edge of the coastal foreland. It is likely,
however, that the lower portions of some of the channels continue below thecoastal sediments. These channels, particularly along their present lower portions,
have sediment infills that accumulated contemporaneously with the formation of
the coastal foreland and thus preserve valuable evidence of mid- to late-Holocene
environments.
Traces of Mesolithic occupation occur mainly on the glacial deposits along the
edge of the foreland, within a few hundred metres of the break of slope which
marks the limit of the early Holocene marine transgression. Mesolithic artefacts
have also been recovered from the shingle ridges surrounding the Williamsons
Moss basin which are known to have formed by c.6950 cal BP. Over 30 lithic
scatters with a definite or suspected Mesolithic component have been recorded to
date (Fig. 2.2), exposed where the modern vegetation was disturbed by ploughing
or burrowing animals. Between 1974 and 1986 sites were investigated at Monk
Moors and Williamsons Moss.
Development of the coastal foreland
The evidence relating to sea-level change and shoreline development in the
Eskmeals coastal zone has been discussed by Bonsall et al. (1986, 1989). The
evolution of the coastal foreland is illustrated in Fig. 2.3 and may be summarized
as follows: Early Holocene sea-level rise culminated in the contemporaneous erosion of
the landward glacial deposits and formation of the innermost shingle ridge
between c.7450 and 7850 cal BP. Estuarine sedimentation began in the lee of
this shingle ridge (Fig. 2.3a). Mean High Water of Spring Tides was then c.2 m
above that of today. Subsequently, and with only a slight fall in sea level, the greater part of the
shingle ridge complex that underlies the Eskmeals foreland was constructed.
The shingle ridges around Williamsons Moss were deposited prior to 6950 cal
BP and a new phase of shingle ridge development which had been preceded bya net fall in relative sea level of c.1 m was underway by 4950 cal BP. This
intermediate sequence of shingle ridges continued to form until after 3900 cal
BP (Fig. 2.3b), their formation being accompanied by progressive abandon-
ment of the estuarine sediments landwards of the shingle ridges. The sea subsequently fell by 0.8-1.1 m and a further phase of shingle ridge
development was in progress by 3000 cal BP (Fig. 2.3c). There have been at
least two periods of sand dune activity on the foreland, the first between 3500
and 1700 cal BP, and the second sometime after c.1400 cal BP. An earlier
phase of sand dune activity may be suggested by a very sandy facies near the
base of the estuarine sediments closest to the main shingle ridge complex.This
would have occurred at sometime between 6950 cal BP (probably after 6300
cal BP) and 3750 cal BP.

Settlement location and coastal change
The Eskmeals sites are all situated on seaward-facing slopes overlooking stretches
of former coastline that experienced predominantly estuarine conditions during
the period of Mesolithic settlement, whereas settlement traces are lacking in areaswhere estuarine conditions were never established during the mid-Holocene for
example south of Stubb Place. This pattern is repeated in coastal areas
throughout Europe where late Mesolithic settlements typically are found in
sheltered locations around estuaries, lagoons or marine inlets (cf. Larsson, 1991).
Several authors have observed that river estuaries offer a greater abundance and
variety of potential food resources than most other coastal environments (e.g.
Jacobi, 1973; Clarke, 1976; Bonsall, 1981). Other resources may also have been a
significant factor in settlement location at Eskmeals. The only locally available
source of flint would have been the shingle deposits of the coastal foreland. Thesedeposits would also have been the most accessible sources of sand and stones
known to have been used extensively for construction purposes (see below). The
main site locations at Monk Moors and Williamsons Moss would have been
ideally situated to exploit these resources.
Another interesting feature of the site distribution is the tendency for lithic
scatters to occur along the margins of former channels cutting across the glacial
sediments. This relationship is particularly evident to the landward of
Williamsons Moss (Fig. 2.4) but was also noted at Monk Moors (see below).The
significance of these channels for Mesolithic settlement is uncertain. It seems
doubtful that they acted as sources of fresh water. Although the channels wouldhave carried away rainwater running off the slopes adjacent to the coastal
foreland, during the mid-Holocene they are unlikely to have been occupied by
perennial streams. Certain of the channel mouths, however, would have provided
a means of access to the foreshore particularly in the area between Monk Moors
and Stubb Place where, at the maximum of the transgression, the sea was actively
eroding a cliff some 3-15 m high. It is also possible that where estuarine
conditions obtained the channels had economic significance. Salmon and sea
trout are known to spawn in large numbers in the mouths of small channels and
feeder streams leading into the present estuary. It has been suggested that lithicscatters often represent former rubbish dumps (Bonsall, 1992), and in some
instances wet channel margins may have been chosen simply as convenient places
for disposal of occupation refuse (cf. Bonsall et al., 1993).
Since environmental factors such as the nearby presence of estuarine
conditions appear to have had a major influence on Mesolithic site location, it
may be presumed that the chronology of settlement at the different sites will
relate to coastal evolution and the progressive establishment of suitable
conditions in the Eskmeals area. As estuarine conditions were first established
(between 7450 and 7850 cal BP) in the area between Monk Moors and
Newbiggin, settlement may have first occurred in that area at that time. In
contrast, the Williamsons Moss site faced onto the open coast until after the
construction of the shingle ridges that formed the Williamsons Moss basin at

c.6950 cal BP, implying that after this date that locality would have been more
attractive for settlement. It is therefore interesting that the earliest dated
occupation at Monk Moors was at c.7650 cal BP, while the earliest dated
occupation at Williamsons Moss was at c.6350 cal BP (see below).This apparentrelationship between periods of site occupation and environmental conditions
suggests that as sea level fell, occupation may have continued longest in the Monk
Moors-Newbiggin area where estuarine conditions lasted longest (cf. Fig. 2.3),
and that Williamsons Moss would have retained its attraction for human
settlement as long as an open lake occupied the area of the present moss.
THE MONKMOORS SITES
Archaeological excavations at Monk Moors between 1974 and 1977 investigated
two lithic scatters which lay on opposite sides of a small infilled channel near the
point at which it is truncated by the sharp break of slope that defines the edge of
the coastal foreland (Bonsall, 1981). These are unstratified, surface sites.
Within the excavated areas the archaeological remains occurred mainly in the
upper 30 cm of a soil which is developed in stony reddish till. The sites proved
to have been severely disturbed by recent agriculture. The lithic artefacts
were mixed through a topsoil (Ap-horizon) overdeepened by ploughing, and
structural remains were preserved only as truncated features at the top of the
underlying B-horizon. With the exception of small amounts of wood charcoal
and rare carbonized fragments of hazelnut shells, no organic materials hadsurvived. A small exploratory trench excavated through c.1.5 m of silty clays
infilling the channel between the two sites revealed no finds of archaeological
significance.
Large assemblages of flaked stone artefacts were recovered from the excavated
areas, that from Site 1 (to the north of the infilled channel) comprising over
30,000 artefacts. The Monk Moors sites (and Williamsons Moss) show a close
resemblance in the forms of the artefacts present and the composition of the
assemblages (Fig. 2.4). The retouched tools show a predominance of narrow
blade microliths (characteristic of Mesolithic sites in northern Britain postdatingc.10,350 cal BP) and scrapers. Among the dbitage both bipolar and platform
cores are well represented. Heavy-duty implements, such as core axes and
bevelled stone implements, are conspicuously absent from the Eskmeals sites.
Small pebbles of flint, and occasionally chert or tuff, appear to have been the only
lithic materials utilized for toolmaking and, presumably, were collected from
shingle ridges near to the sites.
Other traces of prehistoric human activity at Monk Moors comprised
numerous pieces of red ochre recovered from the topsoil on both sites, a series of
hearths and stake holes identified on Site 1, and several shallow depressions
(possibly hearths) and a pit on Site 2. Interpretation of these features isproblematic. They may be traces of actual habitation, but are perhaps better
explained in terms of activities involving processing or storage of food or raw

materials (Bonsall, 1981). Moreover, radiocarbon dating indicates that they relate
to more than one phase of occupation (Table 1). Charcoal from a hearth on Site
1 was dated as 6750 155 BP (BM-1216), indicating that the hearth relates to
use of the site during the Mesolithic. This feature formed part of a linear clusterof hearths and stake holes which may belong to a single phase of occupation.
Charcoal samples from a second hearth on Site 1 (isolated from the main group)
and a hearth and a pit on Site 2 gave dates respectively of 3650 120 BP (BM-
1395), 4050 55 BP (BM-1385) and 2860 50 (BM-1386) BP, suggesting that
these features relate to post-Mesolithic activity.
It is apparent from the radiocarbon and other evidence that the two sites
investigated were occupied on a number of occasions between c.7650 and 2900cal BP, indicating that the coastal foreland retained its attraction for settlement
long after the Mesolithic period. The pattern of repeated occupation of the same
site locations implied by these data also opens the possibility of more than one
episode of Mesolithic occupation at Monk Moors.
THE WILLIAMSONS MOSS SITE
The archaeological site investigated lies at an elevation of c.7.5 m O.D. and is
centred on a low spur extending north westward from a ridge of till towards theshingle ridge at the margin of Williamsons Moss. The land rises steadily to the
east of the site to a height of 15 m O.D. On either side of the spur the landsurface
falls gently to a point lower than the top of the shingle ridge and has been subject
to ponding of water behind it resulting in the accumulation of fine alluvial
sediments. These attain their greatest thickness in the southern part of the site
where they infill a narrow channel cut into the till one of a series of channels
that once drained the surrounding slopes (Fig. 2.5).
A partial excavation of the Williamsons Moss site was undertaken between
1981 and 1986 (Fig. 2.5). A palaeo-landsurface could be identified beneath the
alluvial sediments. Traces of Mesolithic occupation were demonstrated to occuron this palaeo-landsurface over an area of at least 7500 m2. Thus, unlike at Monk
Moors, over much of the site area the archaeological remains were in a sealed

context and showed few signs of postdepositional disturbance.
It was established by means of test pits that the greatest concentration of
artefacts occurred in an area roughly 50 x 30 m on the crest of the till spur. In
subsequent excavation an assemblage of more than 34,000 worked pieces of flint,chert and tuff, including over 600 microliths and other retouched tools, was
recovered from an area of just 125 m2 (Fig. 2.5: Area A). On the crest of the spur
there was no apparent build-up of alluvial material, the soils having developed
directly on till. Hence the archaeological remains there were unstratified. The
lithic artefacts were mixed through the upper 30-40 cm of the soil profile. This
mixing was probably caused principally by bioturbation (perhaps aided by human
occupation disturbance) rather than ploughing. The few structural features
identified, comprising hearths, small pits and several possible stake holes (Bonsall
et al., 1989: fig. 40), were truncated by the modern A-horizon.
In the lower-lying areas below the crest of the till spur lithic artefacts occurredmainly on the palaeo-landsurface beneath alluvial sediments, although artefact
densities were very low (usually

palaeo-landsurface, however, contains other evidence of human activity.
Excavation exposed a number of concentrations of medium and large rounded
stones forming a distinct layer on either side of the till spur. The stones contrast
with those in the surrounding sediments and were probably derived from nearbyshingle deposits.This layer is therefore interpreted as the remains of stone floors
(stone pavement) laid down to consolidate a poorly drained clayey soil easily
puddled by trampling. The main expanse of stone pavement examined lay
between the crest of the till spur and the infilled channel (Fig. 2.5: Area B). From
their stratigraphic context, the stone floors are presumed to relate to Mesolithic
occupation (Bonsall et al., 1986, 1989).
Two trenches were dug to investigate the deposits within the infilled channel
(Fig. 2.5: Areas E1 & E2). Consisting largely of silty clays (see below), these
deposits resemble the alluvial sediments in other parts of the site. Two types of
structure were found stratified within the channel sediments and appear to relate
to a palaeo-landsurface c.90 cm below that of today. One is a raft-type foundation
consisting of two sets of oak branches arranged in a grille or lattice pattern,
overlain by a layer of black, well-humified peat composed of twigs, branches and
bark interpreted as the remains of a layer, or series of layers of birch brushwood
placed on top of the timber lattice. Examples of this type of structure were found
in Area E1 (Fig. 2.6: Structure 1; Fig. 2.7) and Area E2. The second type of
structure consists of areas of made ground retained by a revetment of large
radial sections of oak trunks. An example of this type was partially exposed in
Area E1 (Fig. 2.6) and was overlain by a peaty layer containing abundant birchbark fragments interpreted as the remains of a bark floor (Fig. 2.6: Features 53 &
80). A similar feature, but lacking evidence of a birch bark floor, occurred in Area
E2. It can be suggested that these structures were built to consolidate soft ground
formed by the alluvial sediments infilling the channel. It seems likely that they
were intended to form platforms raised above the level reached by water
ponding behind the shingle ridge. Comparison with similar finds made at
Mesolithic sites in southern Scandinavia can be used to suggest that the layers of
birch bark associated with Structure 2 are remnants of the internal floors of one
or more buildings, possibly houses, constructed on the platform and adjacentchannel margin.
Structures 1 and 2 are dated by six radiometric 14C determinations (Table 2). A
sample of oak from the foundation of Structure 1 gave an age of 6015 75 BP
(UB-2544). Two samples of birch bark from the base and upper part of the
overlying layer of decayed brushwood respectively gave dates of 5555 40 BP
(UB-2545) and 5650 50 BP (UB-2546). Three samples of birch bark from the
two principal areas of bark flooring associated with Structure 2 gave ages of
5520 85 BP (UB-2712) and 5500 70 BP (GU-1664) [F80] and 5480 90
BP (UB2713) [F53]. The dates on bark should approximate most closely the
period of construction. These dates are statistically indistinguishable and indicatethat Structures 1 and 2 were built c.5550 BP. The difference in age ofc.450 years
indicated by the date for one of the foundation timbers of Structure 1 and those

for the decayed brushwood covering of this feature can be explained, in part, by
the (re-)utilization of old timbers for the foundation of this structure (Bonsall etal., 1989).
No diagnostic artefacts were found in direct association with either Structure 1
or Structure 2. Elsewhere on the site there are large numbers of diagnostically
Mesolithic artefacts and no clearly Early Neolithic artefacts, either of stone or
pottery. Moreover, the date of c.6350 cal BP assigned to the structures is
significantly older than the earliest securely dated occurrences of Neolithic
artefacts in northern Britain. The structural remains in Area E1, therefore, are
most likely to relate to occupation of the Williamsons Moss site by people who
possessed a Late Mesolithic material culture. No dates are available for the timber
structures in Area E2, but the general similarity in form, construction techniqueand stratigraphic context to those in Area E1 suggests that the Area E2 structures
also relate to Mesolithic occupation of the site.

As at Monk Moors, there is some evidence for post-Mesolithic use of the
Williamsons Moss site. Artefacts, hearths, and lenses of introduced beach sand
and pebbles occurred within the alluvial sediments above the palaeo-landsurface,
although there was no indication of major or prolonged settlement activity
following the period of Mesolithic occupation. Three hearths at different levels
within the alluvial sediments have given radiometric 14C ages of 3665 40 BP
(UB-2568), 3755 105 BP (BM-1396) and 4925 165 BP (UB-2711)
consistent with their relative stratigraphic positions (Table 2).
VEGETATION HISTORY AND HUMAN IMPACTS
Palynological investigations were undertaken in conjunction with the
archaeological excavations at Williamsons Moss, in order to obtain information
on vegetation changes and possible human impacts around the time of the
Mesolithic occupation. Pollen profiles were obtained from the infilled lake basin
at Williamsons Moss and from the infilled channel deposits of the archaeological
site (Bonsall et al., 1986, 1989;Tipping, 1994).The Williamsons Moss pollen site is located c.270 m to the south west of the
archaeological site, in the deepest part of the infilled lake basin (Fig. 2.5, P1).

the later phase (including a hearth, some sherds of Middle Neolithic pottery,
and a leaf-shaped arrowhead) appears slight compared to the extensive evidence
of Late Mesolithic occupation.
CHARACTER OF THE MESOLITHIC SETTLEMENT
In some parts of Europe such as southern Scandinavia many large coastal
settlements of the later Mesolithic are suspected as having served as residential
base camps occupied on a permanent or semi-permanent basis founded on
seasonal scheduling of coastal and inland resources (e.g. Rowley-Conwy, 1983).
Few of these sites have produced substantial architectural remains, but some have
faunal assemblages which suggest year-round occupation. Bonsall (1981)
proposed a model of the subsistence economy of Late Mesolithic groups in the
Eskmeals area which emphasized the role of fishing and coastal resources, and the
potential for year-round settlement. Unfortunately, the Eskmeals sites lack direct
evidence of subsistence activities in the form of animal and plant remains against
which this hypothesis could be tested.
The Williamsons Moss site, however, exhibits a number of features which
could be expected to have characterized the residential base of a sedentary
Mesolithic community. It is a large and complex site. The remains of Mesolithic
occupation extend over a substantial area and there are zones within the site area
which appear to have been associated with different activities, such as habitation
(the infilled channel) and refuse disposal or implement manufacture/use (thelithic scatter). From pedological evidence, Bonsall et al., (1989) envisaged a large
clearing for settlement which involved removal of trees and ground vegetation
and removal or erosion of the surface soil, resulting in exposure of the subsurface
mineral horizon over a substantial area around the till spur.
The architectural remains are among the most extensive and elaborate
recorded from a European Mesolithic site. There is also evidence that the
brushwood covering of Structure 1 and the bark floor overlying Structure 2 were
each renewed on several occasions (Bonsall et al. 1989; and below), implying use
of these structures over a number of years, even decades. The structural remainspreserved within the infilled channel, however, may represent only a small
proportion of the timber architecture originally present on the site. Systematic
probing has also demonstrated the presence large timbers in a small channel to
the north of the till spur (Fig. 2.4). Since the preservation of organic materials on
the site appears to be related to waterlogging and deep burial beneath alluvial
silts, any timber and bark structures erected in the better-drained areas beyond
the channel margins are unlikely to have survived.
It is likely that a sedentary Mesolithic community would acquire most of its
food and raw materials from within a short distance of the home base. Since raw
materials used in the manufacture of implements are likely to have been obtainedincidentally to the execution of other subsistence tasks (cf. Binford, 1979), the
intensive use of local materials reflected in the lithic assemblage from
40 STUDIES IN NORTHERN PREHISTORY
8/3/2019 2007 Eskmeals(Human-Environment Interactions)
17/19
Williamsons Moss implies that the Mesolithic population focused its activities on
the coastal zone.
There are, however, limits to what may be inferred from the available data.The
evidence from the Williamsons Moss site suggests sedentism, but does notdemonstrate it. From radiocarbon evidence alone it cannot be demonstrated that
the structures within the infilled channel relate to a continuous period of
occupation. The lithic scatter and areas of stone pavement cannot be dated
directly. Consequently, it cannot be proved that these features are
contemporaneous, nor that either relates to the phase(s) of occupation
represented by the timber platforms. Similarly, it is doubtful if from pedological
evidence the effects of a single large clearing for settlement could be distinguished
from those of a series of small contiguous or overlapping clearings associated with
separate occupation events.
Tipping (1994) has suggested from palynological evidence that there is
unlikely to have been a large area of open ground around the channel at the time
of platform construction. This interpretation assumes that the pollen entering the
channel sediments was derived largely from vegetation growing on the margins of
the channel. If, however, Mesolithic settlement resulted in complete suppression
of the vegetation over a substantial area around the channel, as suggested by
Bonsall et al. (1989), then the pollen recruitment zone would have been
considerably enlarged and the pollen entering the channel sediments at that time
would reflect vegetation growing some distance (possibly hundreds of metres)
away. In effect, such a clearing would be invisible in the pollen record. It might,however, be reflected by an increase in the occurrence of microscopic charcoal in
the channel sediments. It is doubtful, therefore, whether pollen analysis by itself
can provide an accurate impression of the nature and scale of vegetation
clearances associated with Mesolithic settlement.
RETROSPECT
The Eskmeals Project has been an important addition to the archaeological record
of north-west England. In particular, it has made a significant contribution to ourunderstanding of humanenvironment interactions in the Late Mesolithic.Yet two
decades after the last trench was backfilled, the Monk Moors and Williamsons
Moss sites remain the only Mesolithic sites on the Cumbrian coastal plain to have
been systematically investigated within an interdisciplinary research framework.
Unsurprisingly, therefore, there are many questions concerning the Mesolithic
settlement of the Cumbrian coast that remain unresolved, not least those relating
to subsistence, sedentism and the transition to farming. These are an obvious

ACKNOWLEDGEMENTS
This paper is dedicated to Clare Fell who took a keen interest in the Eskmeals
Project. She was a regular visitor to the excavations throughout the 12-year
duration of the project. I will always be grateful to Clare for her kindness and
support, and for her remarkable archaeological insights.
