Faifley Rocks WH19

This is a summary account of the excavations at Whitehill 3, 4 and 5 rock art panels between 13th and 19th August 2019. This report was written with co-director, Yvonne Robertson. This is a brief and provisional account, with a more detailed publication to follow in the future.

Faifley Rocks! is a project researching prehistoric rock art sites to the north of Faifley, Clydebank, West (and as it turns out East) Dunbartonshire, using excavation, survey, oral history and archival research. The largest rock art site in the area, the Cochno Stone, has received the most attention, but sits within a small group of c 16 rock art panels. Some of these sites were identified in the late nineteenth century, others through more recent fieldwork, but no comprehensive work has been done on any of these sites since Ronald Morris’s fieldwork in the 1960s and 1970s (reported on in Morris 1981).

This was the second excavation as part of the project, following work at Auchnacraig in June 2019. The summary report of this excavation includes some more background on the project which need not be repeated here.

Whitehill 2019 excavations

In August 2019, excavation took place around three of the rock art sites in the area, sites known as Whitehill 3, 4 and 5 in Scotland’s Rock Art Project (ScRAP) database. These outcrops are situated within a small area of woodland amidst arable fields immediately to the northeast of Whitehill Farm and north of Law Farm on a prominent landscape position with extensive views to the south. The outcrops are sedimentary, being gritstone or sandstone. They are located around NS 5138 7403 and are listed in canmore. These are just inside East Dunbartonshire and hence not quite on the map below right!

Two of these sites were first recorded in the 1960s by Morris unlike the Auchnacraig sites which were first documented in the late nineteenth century. Morris documented these in his 1981 book The prehistoric rock-art of southern Scotland (except Argyll and Galloway). The numbering system he used is slightly different to the system adopted here; we are adopting the ScRAP nomenclature.

Whitehill 3 is the most extensive of the panels and located on the edge of an escarpment. Morris called this site Whitehill 5. It was initially briefly documented in the Morris and Bailey gazetteer (1967, 161) as a hilltop or break of slope location decorated with 25 cups and a few cups-with-rings. This is reflected in a sketch that is within his archive at HES (see below).

In 1971, Morris uncovered an area some 10m by 10m (although his plan suggests a smaller area was looked at) and found more symbols. He recorded, ‘5 cups-and-two-rings, at least 21 cups-and-one-ring, and at least 40 cups. Radial grooves were noted in some instances, and dumb-bell shapes identified’ (1981, 130).

In March 2019, these panels were subject to detailed recording and photogrammetry as part of SCRAP. RTI survey of Whitehill 3 was also undertaken by a team from Glasgow School of Art. The SCRAP record for this site notes that 22 cupmarks, 13 cup-and-ring variants and 7 grooves were recorded; the latter are distinctive oblong cupmarks that the record sheet calls ‘courgettes’. An enigmatic graffiti symbol was also noted; this had been pointed out to me on previous visits. Connections between symbols and ‘fissures’ were noted.

During the SCRAP and Glasgow School of Art surveys, the site now called Whitehill 4 was discovered c20m to the south. This is described in the SCRAP Project database as a ‘domed sandstone outcrop’ that has four cupmarks, one of them dubious. Morris noted additional cupmarks at Whitehill but did not formally document them; this is probably one he spotted and referenced (1981, 133).

The third panel in this location, 25m south of Whitehill 3, is known as Whitehill 5 in the SCRAP database. The survey in March 2019 identified seven cupmarks on this stone, which was entirely covered in turf at the time.

It is not clear if this is the same as Whitehill 6, a site was first recorded by Morris during the visit to the location in 1971 already noted above, having been found by a JM Stables (Morris 1971; 1981). Morris noted that the rock was carved with a ‘much-weathered cup-and-two-complete-rings, slightly oval’ (1981, 133) and suggested it was 55m south of SCRAP Whitehill 3. This site appears similar in Morris’s Plates 123 and 125 (see images below) but the presence of a clear cup-and-ring mark, and its location info, suggests this is a different panel.

Objectives: August 13-19th 2019 excavation

The specific research questions for the excavation of these three panels were:

  • Do carvings extend beyond the currently exposed outcrop?
  • What evidence is there for activity in prehistory, and in the twentieth century?
  • How do the panels physically and spatially relate to one another?
  • Are there any other carved stones in the vicinity? Morris noted others that are not accounted for in the SCRAP survey eg Morris’s Whitehill 6 and 7.
  • Is there additional historic graffiti on the rock art at Whitehill?
  • What is the significance of the location of these sites eg in relation to views and other rock art such as Law Farm sites and SCRAP Whitehill 1-2?

Methodology

The excavation was conducted between the 13th and 19th August 2019 by Glasgow University staff and students, and local volunteers. Upon arrival, the area was subject to a visual inspection to ascertain the condition of the outcrops containing rock art and any further possible features and archaeological remains.

Essentially we ended up clearing vegetation from the outcrops rather than excavating the surrounding area due to the extensive nature of the bedrock.

Cleaning low res

Three ‘trenches’ were laid out focusing on the exposed outcrops at Whitehill 3, 4 and 5. Seven small test pits were also excavated (all but one measuring 1m by 1m) which were positioned in the surrounding woodland targeting areas of archaeological potential both on the ridge and in the valley below. The trenches and test pits were all hand dug, with contexts and rock art being recorded in plan and section, as appropriate, by measured drawing, digital photography, and written descriptions on pro forma sheets. Photogrammetry was also conducted on all three exposed rock art outcrops. After excavation and recording the excavated material was replaced and the turf reinstated.

Results

Trench W3

Trench W3 aimed to investigate the largest of the three known Whitehill rock art sites, Whitehill 3, where a number of cup marks were already visible on an exposed outcrop of bedrock.

A trench measuring 5.0 m by 5.0 m was opened over the exposed outcrop and the flat top to the west and north covered with a shallow layer of turf and topsoil. An extension measuring 2.5m by 1.0m was opened to the west of the trench as well as an extension to the north-east measuring approximately 2.5 m by 2.0 m in order to investigate a wider area for potential rock art symbols. Turf was also cleared off the steep slope of the outcrop to the east in order to investigate the potential for further symbols.

WH3 low res a

Where present, the topsoil comprised a shallow layer (0.15m) of loose medium to dark brown silt loam (context number 301/303) which contained modern glass, plastic and metal as well as a small quartz pebble (Find 1) recovered from a crack in the bedrock. The topsoil directly overlay the natural bedrock (300) in the majority of the trench although pockets of a medium orange brown silt clay with infrequent small pebble inclusions (302) and a medium dark grey silt clay with frequent angular stone inclusions measuring 0.05-0.10 m (304) were recorded in pockets across the trench within natural fissures in the bedrock. This material was relatively sterile and was interpreted as natural hill wash. Disturbance caused by tree roots was apparent throughout deposits across the trench.

WH3 low res b

Bedrock (300) was encountered across the entire trench. The bedrock was a large flat-topped sedimentary outcrop which sloped steeply downwards to the east and gently sloped to the north, west and south.  Up to 65 carved symbols, including c. 33 cupmarks, 16 cup-and-ring marks, six cup-and-ring marks with double rings, eight oval/elongated cupmarks or grooves and at least two radials, were recorded within the trench, largely concentrated on the flat top of the outcrop (see photos). The symbols were of varying size, depth and quality, and dispersed in no clear pattern across the outcrop, and some had clearly been weathered as a result of having been exposed.  Large natural cracks where the bedrock had fragmented in parts were visible across the surface in a north-east to south-west orientation and these areas were devoid of markings. A graffiti symbol was also recorded on the bedrock (300) where the rock had previously been exposed; the meaning of this symbol remains unknown.

Trench W4

Trench W4 measured 4.0 m by 3.0 m and was centred on a bedrock outcrop to the south-west of Whitehill 3 known as Whitehill 4. Prior to excavation, four cupmarks were visible on the bedrock outcrop and the trench aimed to investigate whether further symbols were present as well as whether any further archaeological features were present in the area surrounding the outcrop.

Context 405

The trench was largely covered by topsoil (401) comprising a friable dark black brown clay loam with occasional angular stone inclusions (measuring 0.05 – 0.20m) as well as rare charcoal flecks. Modern glass and plastic as well as a post-medieval or modern ceramic fragment (SF 2) were present within the topsoil. The topsoil directly overlay bedrock (400) in the centre of the trench, however, an underlying clay silt wash comprising dark brown clay silt with occasional angular stones and frequent charcoal (402) was recorded in pockets of the trench within undulations in the bedrock (400).

WH4 after first clean

This deposit also overlay what initially appeared to be a rubble stone wall comprising angular stones (measuring 0.08m – 0.30m) in the north-west corner of the trench. Further rubble material was encountered to the immediate east of this within a large sub-rectangular depression (404). Fragmented bedrock as well as other fragmented stone within a grey silt wash matrix similar to (402) filled the depression and may have been a leveling deposit within a natural hollow, purposefully placed for a platform or trackway or naturally occurring.

To the south of the Whitehill 4 outcrop, a clean light grey sand was recorded below (402). The material was sterile and appeared to have been a naturally washed in deposit directly overlying the bedrock.

W4 plan

No further symbols were observed on the bedrock (400) nor were any further archaeological features recorded in the surrounding deposits.

Trench W5

Downslope and to the south of Whitehill 4, a trench measuring 2.0 m by 0.5 m with a roughly rectangular extension to the south-east measuring 2.5 m by 2.5 m was excavated. The trench focused on an outcrop recorded as Whitehill 5, previously exposed by SCRAP, where three cupmarks were visible on the exposed outcrop prior to the removal of any material. Topsoil (501) was found to extend across the rest of the trench and comprised a friable medium orange brown silt loam with extensive root disturbance and organic material and generally had a depth of 0.10m. The topsoil directly overlay bedrock in much of the trench although a silt clay wash deposit (502) formed a subsoil between the topsoil (501) and the bedrock (500) in the east of the trench. This material was largely sterile and there was clear root disturbance.

WH5 cupmarks

In addition to the cluster of three previously recorded cupmarks associated with Whitehill 5, a further seven possible cupmarks were observed approximately 1.5 m east on the same bedrock outcrop (500) (Plate 7). These were recorded to the east of a large sub-circular area of conglomerate within the bedrock (500). No further features were encountered within the trench and no small finds were recovered.

Test-pits

Seven test pits were opened in all, all bar one measuring 1m by 1m. The location of these is shown in the general site plan above.

Test Pit 1

Test Pit 1 was located at the most northerly point of the ridge on which Whitehill 3, 4 and 5 were situated, c. 45 m north of Trench W3. The test pit targeted this area as it was the highest point on the ridge and found to be relatively level with views of the landscape extending south-east towards the Clyde Valley and to the north-west towards the Kilpatrick Hills. The test pit measured 1.0 m by 1.0 m and was excavated to a maximum depth of 0.30 m.

Topsoil extended across the entire test pit and comprised a friable dark black brown silty loam with occasional angular stone inclusions (0.02m – 0.08m in size) (1001). The topsoil was rich in organic material with some root disturbance. Frequent glass was encountered within the deposit. Beneath the topsoil, medium orange brown clay silt with occasional stone inclusions (1002) was recorded which extended to a maximum depth of 0.20m. This overlay the bedrock (1000) which had an undulating surface within the test pit and sloped downwards from west to east.

No symbols or archaeological features were observed in Test Pit 1, nor were any artefacts recovered.

Test Pit 2

Test Pit 2 was located c. 24 m to the north-west of Trench W3 in a relatively flat area, devoid of turf and simply covered in organic woodland debris. The test pit was placed in this location to determine if there were any archaeological features within this area which could be related to the rock art sites to the south. The test pit measured 1.0 m by 1.0 m and was excavated to a maximum depth of 0.35 m.

TP2

A friable medium black brown silt loam with occasional angular stone and rare charcoal inclusions formed the topsoil (2001) within the test pit and continued to a maximum depth of 0.10m. Modern activity in the area had clearly occurred as glass and modern metal cans were observed throughout. A firm medium orange brown sandy silt with frequent small roots and rare small angular stones formed a natural subsoil (2002) beneath the topsoil and this directly overlay the bedrock (2000). The subsoil deposit was relatively sterile, although some charcoals flecks were noted likely as a result of surface burning and root bioturbation.

No significant archaeological finds or features were recorded.

Test Pit 3

Test Pit 3 was situated c. 7 m north-west of Trench W4 in the centre of a shallow sub-circular hollow. The hollow, although appearing natural, was thought to have archaeological potential and the trench was situated within it to investigate whether features may be present within the area. The test pit measured 1.0 m by 1.0 m and was excavated to a maximum depth of 0.20 m.

TP3
Eric and Ross working on Test Pit 3

An organic vegetation layer (3000) covered the test pit and overlay topsoil comprising a loose light brown organic loam (3001). Beneath this, a natural subsoil comprising a clay silt wash (3002) was observed which continued to a maximum depth of 0.19m which contained patches of compact orange disintegrated sandstone (3003) and overlay the undulating bedrock (3004) (Plate 8).

TP3 sketches

There were no traces of significant archaeological remains within the test pit.

Test Pit 4

Test Pit 4 was positioned c. 5m south-west of W3 and targeted a partially exposed outcrop of bedrock. The aim of the test pit was to investigate if further unrecorded rock art symbols were present on smooth outcrops in the immediate area. The test pit measured 1.0 m by 1.0 m with a maximum depth of 0.10m.

A small outcrop of bedrock (4001) was already exposed and only shallow topsoil was found to cover the bedrock in all areas of the test pit. The topsoil comprised friable dark black brown silty loam (4000) and modern glass fragments were observed throughout. There was no evidence for archaeological features within the excavated area and no markings were observed on the bedrock which was found to be undulating.

Test Pit 5

Test Pit 5 was located c. 5m east of W5 at the southern extent of the site. The location was chosen as it appeared to be a flat area with the potential for a bedrock outcrop to be directly beneath the turf topsoil. The test pit measured 1.0 m by 1.0 m and was excavated to a maximum depth of 0.30 m.

TP5

The topsoil comprised a shallow loose light brown organic sandy loam (5000) which overlay a very compact light brown sand with frequent angular stones up to 0.25m in size. Beneath this a compact layer of dark brown black sandy silt with some large angular stone inclusions was observed (5002). No significant archaeology was recorded within the test pit.

Test Pit 6

Test Pit 6 was located approximately 22 m west of W4 within a level area in the valley below the ridge. The test pit was excavated to investigate whether there were any features associated with quarrying activity in this area. The test pit measured 1.0 m by 1.0 m and was excavated to a maximum depth of 0.50 m.

The topsoil (6000) comprised a dark red brown silty loam which contained modern glass. This was overlying a light red brown clay sand with angular and rounded stone inclusions of various size (6001). Bedrock was not reached within the test pit. No archaeological finds or features were recorded within the test pit.

Test Pit 7

Test Pit 7 was located c. 21 m west of W3 within a slight hollow on the west edge of the ride. The test pit targeted a supposed flat-topped bedrock outcrop and was also located within this area to investigate the potential for features related to the occupation of the site. The test pit measured 1.50 m by 1.50 m and was excavated to a maximum depth of 0.20m (Plate 9). Peck marks on the flat bedrock surface were identified and probably related to someone trying to get purchase on a tent peg…..

Photogrammetry

Under the guidance of Megan Kasten, teams of students undertook photogrammetry of the three outcrops, which supplemented work already undertaken by SCRAP. In each case more of the rock was exposed than during this earlier survey, and in two cases (W3 and W5) more symbols were exposed as well. These models are still being worked on and final versions will be added to this post, or linked to, in due course.

Discussion 

The excavations at Whitehill have shed further light on three of the known rock art panels at Whitehill. Previously unrecorded symbols were observed and recorded on both Whitehill 3 and Whitehill 5, as parts of the outcrop previously left covered by Morris and SCRAP were exposed, and the areas around the outcrops also investigated.

Whitehill 3 was found to be the largest and uppermost decorated outcrop with a huge number of symbols observed on its flat top and the top of the smooth slope on the eastern side. A wide variety of symbols were recorded with no obvious pattern deciphered. The mixture of type, depth and quality does, however, potentially suggest the rock art was conducted by different people at different times. This is the second most extensive rock art site in the area after the Cochno Stone. The rock art panel known as Whitehill 4 was occupied by four simple cupmarks only while up to 13 single cupmarks were recorded as part of Whitehill 5. There is no evidence as of yet to allow interpretation of the relationship of the individual panels or to either confirm or deny that these cupmarks are contemporary with one another as no datable material was recovered in or around the outcrops.

The symbols on all three panels were limited to areas of smooth bedrock enclosed by glacial striations, with only the best areas for carving having been selected. It was also noted that the symbols were largely limited to the top of the flat-topped outcrops with few symbols on vertical faces. Several other rock outcrops were investigated on the ridge to determine whether other panels were present in the area, however, none were found. The shape and aesthetics of the natural rock surface therefore appear to have played a major role in the selection of the outcrops as well as potentially the design of the carvings, a notion also apparent at Hunterheigh Crag, Northumberland (see Waddington et al 2005).

While the areas around the panels were investigated, few further archaeological features were observed. The only notable feature was observed in Trench W4 focusing on Whitehill 4 where an area of fractured bedrock was found to potentially signify the remains of a wall or leveled area. This feature may be related to prehistoric use of the site, with ‘rubble platforms’ having been found to be contemporary with carvings at Copt Howe (Bradley et al 2019) and also, interestingly, at nearby Auchnacraig 1; however, it could also be a result of later quarrying or landscaping activity in the area. No material was found within the cracks on any of the outcrops despite investigation, based on the results of rock art sites such as Torbhlaren, Argyll and Bute (Jones et al. 2011). The quartz pebble found in W3 was in an area removed from the carvings and more likely ended up there through natural processes.

Later use of the area was noted with the west side of the ridge having visibly been quarried and more recent graffiti observed on Whitehill 3, which was limited to one area of exposed bedrock on Whitehill 3. There is no indication of what this quarry was or when it was in use in nineteenth century maps.

Faifley Rocks AC19

This is a summary account of the excavations at Auchnacraig 1 and 3 rock art panels between 20th and 27th June 2019. This report was written with site supervisor, Alison Douglas. This is a summary and provisional account, with a more detailed publication to follow in the future. The project was featured in the Clydebank Post.

Introduction and background

Faifley Rocks! is a project researching prehistoric rock art sites to the north of Faifley, Clydebank, West Dunbartonshire, using excavation, survey, oral history and archival research. The largest rock art site in the area, the Cochno Stone, has received the most attention, but sits within a small group of c 16 rock art panels. Some of these sites were identified in the late nineteenth century, others through more recent fieldwork, but no comprehensive work has been done on any of these sites since Ronald Morris’s fieldwork in the 1960s and 1970s (Morris 1981).

The starting points for Faifley Rocks have been excavation and survey work related to the Cochno Stone (2015-16, Brophy 2018) and the 3D recording of Faifley’s rock-art undertaken by HES’s Scotland’s Rock-art Project (SCRAP) in 2019.

  • Cochno Stone excavation summary account
  • 3D models of Faifley’s rock art (sites Edinbarnet, Whitehill, Law Farm and Auchnacraig) on sketchfab

Faifley Rocks! intends to:

  • identify features, materials & activity related to rock art decorated outcrops;
  • recover material related to the chronology & environmental context of the rock art;
  • identify additional symbols on buried outcrop areas and explore connections between symbols and aspects of the natural rock;
  • quantify and interpret rock art and graffiti on each rock outcrop;
  • raise the profile of Faifley’s rock-art locally and more broadly;
  • inform ongoing local consultation on the future of the Cochno Stone;
  • support the development of a rock art walking trail in the area and provide information for other forms of public engagement, analogue and digital;
  • work with local communities and schools to provide information, skills and learning opportunities.

The overall intention of Faifley Rocks is to place the rock art within its prehistoric, and contemporary, context, explore the social value of prehistoric rock art and identify ways to use the rock art for social benefit of the local and broader community. As part of this commitment, summary reports on all fieldwork will be posted on this blog.

Auchnacraig 2019 (AC19) excavations

In June 2019, excavations took place around two of the rock art sites in the area, known as Auchnacraig 1 and 3. These are situated within 10m of one another in Auchnacraig Park at the edge of a clearing that was previously occupied by Auchnacraig House. They are located at NS 5028 7366 and NS 5029 7365 and have this Canmore ID.

These two rock art sites (along with nearby Auchnacraig 4 and the Cochno Stone) were first documented in the late 1880s by Rev Harvey (1889). He noted that the carved stone were at that time located in moorland, and that the outcrops bore marks of glaciation. He identified all rocks as sandstone.

Auchnacraig 1 (Harvey called this Rock B) was said to dip at an angle of 30 degrees and was covered in a profusion of cupmarks (up to 90) and some rings, as well as other markings and a large basin. He noted the connection between natural cracks and ‘ducts’, and some of the symbols. Ronald Morris said of Auchnacraig 1: ‘Prominent smooth gritstone slab sloping 30 degrees from 1m high on the east to ground level on west. 7m by 5m. On it are nearly 100 cups…at least 6 are surrounded by weathered rings, mostly now incomplete. These include 3 cup-and-three-rings, one with two radial grooves in the ‘keyhole pattern’. Largest ring 22cm in diameter’ (1981, 85). When Morris visited this site in June / July 1968, it was situated within the garden and lawn of Auchnacraig House. He wrote in his notes from one visit that this rock was only a few metres from the corner of the building, and that the House looked derelict.

Auchnacraig 3 has received much less attention. Harvey called this his Stone C and noted that it was a rock that had seven cupmarks on it. These were, he noted, of ‘exceptionally large diameter’ (1889, 137). Morris simply noted the presence and the existence of a few cupmarks on this surface of the other panel, Auchnacraig 3. He did not give this site its own number and the label Auchnacraig 3 comes from the SCRAP database.

Both sites were also visited by an OS fieldworker in 1951, when the stones were situated in the garden of Auchnacraig House. It was noted that no rings were visible on any of the outcrops (incorrectly in the case of Auchnacraig 1). Both were partially covered in vegetation and located on the edge of a lawn at this time.

In March 2019, these panels were subject to detailed recording and photogrammetry as part of Scotland’s Rock art Project (SCRAP). By this time, as has been the case since the 1980s, the rocks were situated in a cleared area in an urban park, reflecting the remnants of the footprint of Auchnacraig House and gardens.

The SCRAP survey identified several distinctive long ‘gutters’ running down the slope of Auchnacraig 1 which were not recorded by Morris (who presumably felt them to be natural features of the rock). It was also noted that graffiti, and a cup-and-ring mark, are evident on the vertical eastern face of the stone, again previously unrecorded. A more detailed analysis of the symbols and natural features on all rock art sites in the area is currently underway and will be reported on in the future.

June 2019 excavation

The specific research questions for the excavation of these two panels are:

  • Do carvings extend beyond the currently exposed outcrop?
  • What evidence is there for activity in prehistory, and in the twentieth century?
  • How do the panels physically and spatially relate to one another?
  • Was the rock-art incorporated into the garden or any other structures associated with 20th century activity here?
  • Are there any traces left of the house, garden or associated features?

Three trenches were opened as part of AC19, two around Auchnacraig 1 and one around Auchnacraig 3. Furthermore, geophysical survey was undertaken in the area immediately to the east of the rock art in the area of Auchnacraig House and garden. The results of this will be reported on fully once processed.

A number of soil layers were identified within this trench, laid on top of bedrock which sloped to the southwest. These were, in simple terms, an orange-brown soil (105/112) interpreted as a ‘garden soil’ with darker topsoil layers on top (100/113/101).

A concentration of rounded and angular stones was identified hard up against the vertical face of the rock outcrop (102). This consisted of a series of large stones up to 0.3m across; they were set in a roughly level layer consisting of one course of stones. This extended 0.8m out from the main outcrop and extended across the width of the trench. This was set within a matrix of dark silt loam (101) which was similar but darker than topsoil 100/113.

The bedrock was 0.7m beneath the surface at the rock face end of the trench, and 0.08m below the surface at the eastern end of the trench. This is the same sedimentary rock as both rock outcrops with rock art here. There were signs of glacial plucking on this bedrock surface.

Small finds from within this trench were not in secure contexts and included modern rubbish and roofing material, presumably from the house.

Trench A1b

A trench measuring 1.5m by 3.2m was opened on the southern side of Auchnacraig 1 running from a ‘crack’ in the rock; an extension was added to the southern end of this trench, on the west side, measuring 1m x 1.8m.

The stratigraphy in the trench was fairly simple, with a mid-brown clay-slit soil (117), at least 0.7m deep, underlying a fairly shallow dark brown to black loam topsoil (104).

Overlying layer 117 was a drystone kerb or wall was running east-west adjacent to the southern edge of the outcrop (107/108). A gap in this wall about 0.8m across coincided with extensions of the kerb northwards on both sides of this gap for c1m and abutting / overlying the rock outcrop’s southern sloped extent.

Rubble deposit 109 was found in the ‘entrance area’ within and protruding through topsoil 104, consisting of scattered stones up to 0.4m in length although most were much smaller.

A cup marked stone was found amidst the wall, on the western corner of the entrance area. This has not previously been recorded.

Small finds from this trench did not come from a secure context. In topsoil layer 104, a marble was found, and a metal ‘box’ was in the same layer in the ‘entrance’ area.

Trench A3a

A trench measuring at its maximum 4m east-west by 5.4m north-south was opened on the north-east and eastern side of Auchnacraig 3.

Cleaning and recording

Distinctive markings were noted on the rock outcrop including striations running along the rock (glacial markings). A natural vesicle was also noted on a lower section of the outcrop, and while this is natural, it looks like a cup mark. Scrapes on the rock’s upper surface are probably plough marks suggesting that before this was a garden, this area was a field.

This trench had simple stratigraphy. The natural was an orange-brown-pink boulder clay (303) which in places we dug into to establish this was the natural. Above this was an orange-brown ‘garden’ soil (similar to 105/112 in Trench A1b); this layer, 302, was between 0.2 and 0.3m deep and spread across extent of the trench beyond the outcrop. Above this was a topsoil layer, 300, which was a dark brown loam with small stone inclusions. This layer was no more than 0.2m thick and was essentially the same as topsoil layers 104 and 100/113 in the other trenches. No features were found cut into the natural.

Small finds from within this trench were not in secure contexts and were modern debris and roofing material, presumably from the house. There was evidence for fires having been set in the topsoil, modern surface activity.

Discussion

These modest trenches at first glance did not reveal much of prehistoric relevance to the carving of these rock art panels. However, the interplay between natural features and the carved symbols are an important element in the story of this location in prehistory. The natural vesicle found at Auchnacraig 3 looks like a cupmark and may have been regarded as such in the Neolithic period, although unlike a similar feature found at Copt Howe, Lake District, this had not been augmented by a carved ring (Bradley et al. 2019).

The glacial striations and signs of plucking found during the excavation may also have played a role in the significance of these outcrops, not least due to the entanglement of symbols with cracks, veins and so on evident on the surface of Auchnacraig 1. Unlike other rock art sites such as Torbhlaren, Argyll and Bute (Jones et al. 2011), no material was found in any cracks on either outcrop although several large stones are still to be analysed.

The collection of rocks found in Trench A1a was at first glance interpreted as the result of a modern gardening activity. However, it is worth bearing in mind that a similar rocky setting at Copt Howe has been interpreted as a ‘rubble platform’ contemporary with the carving of the stone. This was, as at Auchnacraig, set up hard against a vertical face with carvings on it. Bradley et al (2019) have suggested this architectural trait is shared with Irish passage graves. That the rubble layer at Auchnacraig appears to have sat upon a layer we interpreted as a garden soil suggests this is not a likely interpretation of what we found, but it is worth bearing in mind and we cannot rule out the possibility that these stones were indeed set there in prehistory and our interpretation of the sequence might be revisited. A less well-defined version of this was found at Rock 1, Ben Lawers, Perth and Kinross, during excavations and interpreted as a ‘cobbled surface’ (Bradley et al 2012, 38).

Twentieth century use of the rock art as elaborate garden features is apparent, especially in the constructed wall or kerb on the south side of Auchnacraig 1. This kerb or wall continues for some 2m to the west, before merging or joining a broader coarser wall or bank which runs to the south. Morris’s photos of this stone (such as the one included above from 1968) show a similar drystone wall beyond the rock, suggesting these were two sides of a pathway skirting south of the rock art. This arrangement, and a possible rockery on the west side of the rock outcrop, will be explored in a future season of work.

The inclusion, probably deliberately, of a cup marked stone at the entrance area of the kerb or wall suggests the house owners were keen to celebrate the rock art in their garden and none of this is a coincidence. The discovery of a marble in this area suggests that the rock art outcrop here was not just a garden feature, but a place where children played; the latter was also the case at the Cochno Stone (Brophy 2018). It seems that this richly decorated stone was a matter of some pride for the house owners, and aspects of the garden here were arranged around it.
