What’s in the Pipeline? | The Mesolithic and the lithic in two major infrastructure projects

Two major infrastructure development proposals in north-east England involve onshore and offshore interventions with ongoing assessment of the archaeological impacts:

  1. York Potash Mineral Transport System | Sirius Minerals
    Whitby, Redcar & Cleveland, Teesside, North York Moors National Park
  2. Dogger Bank Wind Farms and Offshore/Onshore Cabling | Forewind consortium
    North Sea, Redcar & Cleveland, Teesside, East Yorkshire, Humberside

How will the Mesolithic fit into the archaeological and palaeo-environmental assessment protocols (desk-based and fieldwork), prospecting-sampling strategies, mitigation-preservation decisions and, if these projects happen, recovery-dissemination-curation? Geophysical prospecting and macro-sampling strategies, for example, are either developing practices for our period and the nature of its archaeological footprint, or are unlikely to be suitably granular for identifying Mesolithic/Neolithic past activity areas. So what happens when the bulldozers go in?

There are two significant development proposals in the Teesside and North/East Yorkshire areas at the consultation/investigation-assessment stages of the planning process. Both involve pipe trenches—one for the transportation of potash-in-solution from near Whitby to a processing plant on Teesside (Wilton) and the second to carry electrical cables from a proposed offshore wind farm on Dogger Bank, landing between Marske and Redcar and progressing to Lackenby (also Wilton). Both projects are required to consider risks to both the natural (ecological) and historical (archaeological and built) environment.

You might be interested to learn more and become involved in the consultations, as a local stakeholder or as an advocate for our heritage.

Major developments challenge us to get involved throughout the process and to balance the prospect of economic & social benefits—proposed and realised—with a conscience around our archaeological assets. While we care about conservation and preservation, we might also see major new discoveries. Can we help manage those through to something which adds perspective and value to an engaged and interested community?

I would only ask what that “community” looks like and why it cares.

1. The York Potash Mineral Transport System | A Sirius Minerals Project

There has already been considerable press coverage, and some accompanying controversy, about Sirius Mineral’s proposed new mine-head at Sneatonthorpe, a few kilometres south of Whitby. For example, listen to the BBC Radio 4 programme “Potash of Gold” (April 2013, audio). Unlike the rail-transported potash from the Boulby mine, Sirius propose a pipeline carrying two steel pipes up to 700mm in diameter buried at a minimum depth of 1.2m that will carry potash in solution under pressurised conditions. Having rejected rail, road and offshore pipelines, the proposed inland route, 44.5km in length, traverses the North York Moors National Park, following the A171 Whitby to Guisborough road for a significant portion, then towards Upleatham (with known Mesolithic presence) to a processing plant on the Wilton industrial complex south of the Tees.

Archaeological impact

The Summary of Proposals Document, which has been sent to communities along the route, reflects an assessment of archaeological impacts conducted by Cotswold Archaeology in 2012. The Sirius proposal document states, in the only reference to archaeology (page 7):

“A heritage assessment has been undertaken to highlight areas of potential archaeology. To date, there are no areas of significant findings that affect the mineral transport system route. Further monitoring* during construction operations is recommended.”

*by which they mean geophysical survey, watching briefs and selective excavation.
 
The archaeological assessment (unpublished) states “A number of undesignated assets are either crossed by the pipeline route, or have the potential to fall within the working width.” 71 out of 257 identified through HER or field survey are specifically called out, spanning the Late Neolithic-Bronze Age through to post-Medieval.

Many will be aware of the stream of unusual, often unique, sometimes nationally important discoveries in a region considered an archaeological ‘backwater’ in the not too distant past.

Consultation

“The pipeline proposal falls within the remit of the National Infrastructure Directorate at the Planning Inspectorate (formerly known as the Infrastructure Planning Commission). More information can be found at:
http://infrastructure.planningportal.gov.uk
. York Potash is already in advanced discussions with local landowners along the route that the pipeline will take from the mine to Teesside. There will be a separate consultation period specifically on the pipeline before any planning application is submitted.” (From the York Potash Project website, see below.)

The Summary of Proposals Document (booklet) can be requested from Sirius Minerals on the York Potash Project website. More information about the entire project can also be found there and there is an invitation to submit comments and questions, although your editor had to wait some weeks for a reply. See also the North York Moors National Park Authority press release (Jan-2013) although the mine-head and pipeline proposals are separate projects.

2. Dogger Bank Wind Farms and Offshore/Onshore Cabling | A Forewind Project

Click to visit websiteForewind is a consortium comprising four international energy companies which joined forces to bid for the Dogger Bank Zone Development Agreement as part of The Crown Estate’s third licence round for UK offshore wind farms. The proposals comprise three elements:

  • An offshore element (the wind farms) located on the Dogger Bank in the North Sea, some 125 to 290km from the coast and covering 8,660 km² with a sea depth of 18 to 63m.
  • An offshore cabling element to bring power to the coast (landfall): (1) Fraisthorpe to the south of Flamborough Head; (2) Between Redcar and Marske near Teesside
  • Cable lines connecting landfall sites with the National Grid at two points: (1) Creyke Beck near Cottingham in East Yorkshire; (2) running to the industrial areas between Teesport and Lackenby (there are four ‘projects’ with two ‘connection points’).

Archaeological impact

There are extensive resources available on the Forewind website including a comprehensive Zonal Characterisation Document (ZCD) (v2 Dec-2011, 21Mb PDF) which includes a full analysis of geology, ecology, archaeology (including wrecks and aircraft) and many other aspects of the onshore and offshore catchments. It is well-structured with copious references and worth a read, irrespective of the proposals.

Dogger Bank, or Doggerland, is part of a post-glacial land-bridge between Britain and continental Europe, probably (with some evidence) intensively occupied and exploited by Mesolithic communities until the North Sea inundation around the seventh millennium BC. The ZCD is skeptical about the survival of offshore archaeological deposits (due to “scouring” during sea-level rise), but acknowledges the significant archaeological and palaeoenvironmental potential of the offshore wind farm zones.

According to the website, Archaeological field surveys and trial trenching along the proposed onshore pipeline routes will be conducted by URS (a US commercial company with UK presence) during May-June 2013.

Consultation

Consultation on Dogger Bank Teesside is being carried out in two formal phases.

Phase One (May-June 2012) | During this phase, “Forewind explained the site selection work done to date, including the process to narrow down the locations of the offshore wind farms, landfalls and converter stations.  Stakeholders were invited to provide comments on the proposals while local people were specifically asked for information on issues to be considered when choosing the precise locations for onshore and offshore elements of the project.” The Preliminary Environmental Information 1 documents and other consultation materials are available to download here and hard copies are available locally from the locations listed here.

The consultation period for these documents is now closed. However, comments may be given consideration if possible. They can be submitted by Email: info@forewind.co.uk | Freephone: 0800 975 5636 | Freepost RSLY-HKGK-HEBR, Forewind, Davidson House, Forbury Square, Reading RG1 3EU

Phase Two (anticipated to be 2013) | During this phase Forewind will ask the local community for comments on the detailed proposals for Dogger Bank Teesside.

Recent feedback and status

Forewind very kindly responded (and gave permission to quote) this statement (April 2013):

“We are working with Wessex Archaeology Coastal and Marine to assess the impact of the Dogger Bank wind farms to offshore archaeology. This comprises the archaeological assessment of both geotechnical and geophysical data aimed at an in depth analysis of the palaeo-landscape and palaeo-environment and the potential for prehistoric archaeology, as well as the assessment of maritime and aviation archaeology. In addition Forewind is working closely with The Crown Estate to record any finds under the ORPAD protocol (Offshore Renewables Protocol for Archaeological Discoveries) as a result of our extensive survey programme.

Onshore, the baseline archaeology assessment is being undertaken by the heritage team at URS www.ursglobal.com and is currently on-going.  We have consulted English Heritage and the archaeology advisor to Redcar and Cleveland Borough Council – Phil Abramson and his colleagues at NEAR, who will no doubt be known to TAS members.  The suitability for geophysical survey was discussed and agreed with Redcar and Cleveland Borough Council.  Subsequently a programme of detailed magnetometry for the onshore cable routes has been carried out, and the interpretation plots are currently being processed.  The results are very clear and several areas of enclosure and trackways have been identified which are indicative of late prehistoric and Roman settlement-related activity.  In addition, the surveys have identified anomalies relating to First World War practice trenches at the landfall.  The fieldwork is being undertaken by Archaeology Services University of Durham and all reports will eventually be uploaded to OASIS and submitted to Tees Archaeology (for their records) and to the council.

We are planning to consult on a draft version of the environmental statement for Dogger Bank Teesside, which will cover both onshore and marine archaeology, in the autumn.  We will send you details of this consultation nearer the time and would appreciate any comments or feedback that Teesside Archaeological Society and the Council for British Archaeology Yorkshire may have.

If you are interested in seeing the level of detail our assessments go into, you could take a look at the draft Environmental Statement for our Dogger Bank Creyke Beck project.  This is on our website at
http://www.forewind.co.uk/downloads/dogger-bank-creyke-beck-downloads/phase-two-consultation.html
and we are inviting comments from any stakeholder.  The deadline for responses is 11 June 2013.”

Mesolithic dig at Goldsborough, North Yorkshire | Every conceivable type of weather

The final phase of the North East Yorkshire Mesolithic Project, funded by English Heritage and directed by Tees Archaeology with the North York Moors National Park Authority, saw a two-week long excavation at Goldsborough, near Whitby. The research project has investigated Mesolithic sites (c. 8000 – 3600 Cal BC) for potential on the high moor watersheds and in the lowland areas like Goldsborough—including sites that might have organic preservation, provide direct palaeo-environmental data (pollen and preserved palaeo-soils), retain features such as stake or post holes, hearths, etc., and yield radiocarbon dating evidence for which there is a complete absence in the whole of north-east Yorkshire. The project aims also included the testing of various archaeological and geophysical survey techniques in the identification and recovery of Mesolithic evidence as well as reviewing assemblages recovered in historical times and through volunteer reconnaissance activities.

Fieldwork in March is always going to be a somewhat tricky affair. Fieldwork in early March on the Yorkshire coast, on a cliff top, is likely to be rather interesting weather, and it most certainly was!

Distant memories of warm (if wet) summer fieldwalking soon evaporated as the snow blizzards and hail rolled in from (apparently) Russia, over huge North Sea waves.

Project director Rachel Grahame commented:

“Despite the weather we achieved everything we set out to do—we have enough shovel pit data to compare to the fieldwalking and the geophysics, we found a ditch (probably Iron Age), a small gully and post pit (could be Mesolithic?) and an area of burnt sandstone, charcoal and unusual stones which could be the remains of a Mesolithic fire. Kevin has washed and re-bagged all the flint and other finds, and they are awaiting assessment by Peter Rowe. We also have environmental samples to be processed, in the hope of finding some dating evidence, and the unusual stones will also be going to a specialist.”

Blizzards | Return of the Ice Age?

OLYMPUS DIGITAL CAMERAOLYMPUS DIGITAL CAMERAOLYMPUS DIGITAL CAMERALocal enthusiasts had come across flint scatters on ploughed fields close to today’s cliff edge—on one of the most beautiful and tallest coastlines in England. Tens of thousands of flints were recovered, unfortunately without grid plotting*, and so the project aimed to identify clusters, as well as conducting a geophysical magnetometer survey to see if features (such as burning) showed up.

*The importance of plotting finds accurately (preferably to the nearest square metre or at least 2x2m grid squares) and seeking professional archaeological guidance cannot be over-estimated. Collecting artefacts, including debitage, even from ploughed fields, removes evidence and cannot be undone. Flints in boxes have little meaning. Our shared ability to reconstruct and interpret past human activities is therefore compromised—forever.

Memories of summer

Flints & flags

Flints & flags

Gridded fieldwalking and shovel pits in previous seasons were aimed at pin-pointing specific areas of activity and interest. Flints (and some Whitby Jet) seemed to reflect activity right through the prehistoric period, with a few finely retouched Neolithic and Bronze Age items. All flints were plotted exactly using a GPS Total Station—hugely expensive and amazing devices.

Provisional results and finds news

The results of this final excavation—over 90 shovel and test pits, and a long trench to test the geofizz “anomalies”—will take time to assess. Tees Archaeology will be cleaning and analysing the finds, and there was at least one charcoal soil sample taken that will need careful specialist scrutiny plus several environmental soil samples to look at.

Selection of stones from Context 116

Selection of stones from Context 116

Features included a modest post hole with adjacent “slot” or scoop (not dissimilar to one found in Penny Spikin’s March Hill excavations in the central Pennines). It’s not inconceivable that it’s Mesolithic. There was a test pit, just behind the crest of the ridge, that produced an area of stones and cobbles, and an elliptical lens of charcoal around 20cm in diameter and 3-4cm deep. It seemed to be surrounded by some of the cobbles and there was a flint blade or two and some spalls between the stones. The stones themselves were odd in that they were different to the natural eroded sandstone and not native to the area. While glacial tills (boulder clay) do exist on the coastal margins south of Whitby (their likely source) they are unusual at this elevation and must have been brought to (or at least arranged at) this spot intentionally. Some stones were heavily burnt—or indeed half burnt (stone ‘a’ in the picture) with a clear line showing where the heat had affected only one side—and one metamorphic piece displayed linear “lattice” groove marks. Whilst these could be due to historical plough or agricultural damage, none of the other stones were similarly affected. All will be submitted to a geological specialist for examination.

Late Mesolithic Microliths similar to those found at Goldsborough

Peter Rowe (Tees Archaeology) will be conducting the lithics analysis of the flint assemblage. Inspection on-site showed at least one “narrow-blade” microlith fragment, some possible microburins, faceted bladelets and blades (some with edge wear from utilisation) and a few small scrapers. Many are consistent with Late Mesolithic activity, and the microlith (a backed micro-bladelet with some opposed edge retouch, possibly the barb from an arrowhead) is diagnostic. Fieldwalking finds also included bladelet cores of conical form and similar blades, bladelets and scrapers. The soils here are acidic and so bone and shell (calcium-rich) do not survive well, if at all. Even prehistoric pottery (Neolithic onwards), usually poorly fired until the Iron Age, succumbs to the soil conditions, erosion and ploughing. Lithics such as flint are generally all that survive, but their spatial patterning, the presence and absence of certain types, can still tell a story about activities, subsistence (microwear), raw material procurement, mobility and approximate dating.

Typical Mesolithic flint core

One further test pit also revealed a small “V” section ditch that may be of Iron Age date. The inclement weather (snow and rain) showed a low-lying area away from the flint concentrations that retained water. Could this be the remnants of a palaeo-lake (or more accurately a modestly-sized pond or pool)? Mesolithic people tended to favour sandy well-drained spots close to rivers, streams, springs and open water—not only for ease of movement through a heavily forested environment, and as familiar “handrail” features in the landscape to return to—but also as focal spots (clearings) that would have attracted game and wild fowl and made hunting easier. A similar situation exists on the Eston Hills at the edge of the Tees basin where a modest wetland area and sandy ridges seem to have attracted both early Mesolithic (Deepcar type tools) and later Mesolithic (Narrow-blade geometric microliths) hunter-gatherers. A palaeo-pool also seems to have been the reason for a cluster of campsites at Esklets & Bimshaw, Westerdale, North York Moors.

Mesolithic background

Mesolithic winter

Enigmatic huts

The stone age people, modern humans like ourselves, that we’re searching for in the Goldsborough area could perhaps be called the “first British folk”. This was the time when the rising North Sea finally cut us off from the continent—Denmark, Holland and Belgium—drowning Europe’s “lost country”, Doggerland, and we truly became the British Isles that we know today, around 6400 BC. There was even a tsunami that finished off the job about 6100 BC, sending giant waves down the east coast and wiping out the last remnants of the lowland forests, rivers and marshes. Like everything British, we did things slightly differently after that, and there’s a big change in the stone tools that people used. The Mesolithic—middle stone age—is still over four thousand years before metal tools and two thousand years before the first pottery.

Microliths_Scalene_Triangles

The first colonisers after the Ice Age glaciers thawed (north of the River Esk and out to sea), at places like Star Carr (Scarborough), had large and distinctive flint tools and antler harpoons. Once we were cut off from Europe the tools become a bit peculiar and get much smaller—like “plug-in” multi-purpose drill bits that could be used for many different purposes such as arrow barbs, needles, drills and knives. Our ancestors had the best DIY kits, perhaps even better than today!

It also looks like these tiny tools, some smaller than a fingernail, begin to appear first in Northern England and Scotland—places like Howick (Northumberland), East Barns and Echline (Firth of Forth) where families seem to have returned to the same places—maybe even settled—over many generations, rebuilding their turf or hide-covered huts several times. Is it the same at Goldsborough?

Final trench

The final trench

Were these the displaced people from Doggerland, victims of global warming, literally moved from their ancestral territories by ever rising tides—a second wave of settlers? One of the project’s aims is not just to find the evidence for the first “Britons” through their stone tools, but to find charcoal from their fires (and roasted hazelnuts were a particular favourite) that we might be able to radiocarbon date.

White Gill Samples

“There are no recent, reliable Mesolithic radiocarbon dates from the North York Moors”

The sale proceeds from this rare run of journals will fund AMS radiocarbon dating of charcoal samples from a Late Mesolithic activity area excavated at White Gill, Westerdale, North York Moors in 2000.

Permission to excavate a rapidly eroding moorland area was granted by the North York Moors National Park Authority and the Estate owners. The rescue excavation of 20m² revealed four hearth-based flint knapping events.

WhiteGill Isometric Plan

One of the hearths was surrounded by stones and an area of piled boulders. Other features included “flat surface” stones and a possible seat or anvil all of which had clusters of artefacts, including utilised blades, scrapers, awl-piercers, microliths—and refits. There was a possible post-hole and an area free of knapping debris that may indicate the location of a shelter. Every flint was spatially recorded, revealing activities—including microlith manufacture—over the excavated area. A rare jet fragment may have been curated.

White Gill re-fitting segmentsDespite over eighty years of largely unpublished flint collecting, there are few recorded features and no recent reliable radiocarbon dates from the prolific sites on the North York Moors. Samples from the fire-spots and hearth contained rosaceae—a short-lived taxa that includes crab apple, hawthorn and sloe. Analysis was generously provided by professional archaeo-botanists, with advice from English Heritage scientists. Lithic analysis is underway with a view to publishing the findings in due course.
