1 SUMMARY OF RESULTS

A detailed magnetometer survey was conducted over approximately 64ha of arable farmland and grassland. Two areas of probable later prehistoric settlement activity have been detected, along with further possible evidence of industrial activity. Former field boundaries, ridge and furrow and evidence of modern ploughing indicate that the site has a largely agricultural past. The remaining features include areas of magnetic debris, trackways, land drains, underground services and areas of natural magnetic variation.

2 INTRODUCTION

2.1 Background synopsis

SUMO Services Ltd were commissioned to undertake a geophysical survey of an area outlined for the construction of Roade Bypass and Phase 2 of works at Junction 15 of the M1. This survey forms part of an archaeological investigation being undertaken by CgMs Consulting.

2.2 Site details

NGR / Postcode The Roade Bypass area is centred around NGR SP 747 516 / NN7 2ND.

The area at Junction 15 of the M1 is centred around NGR SP 743 546 /

NN7 3AG.

Location The Roade Bypass site comprises 15 parcels of land curving around the

west of the village of Roade, Northamptonshire. Blisworth Road runs

through the north of the area, with a dismantled railway running through

the south.

The Junction 15 area comprises 4 fields, each bound to the west by the

London and North Western Railway.

HER/SMR Northamptonshire

District South Northamptonshire

Parish Junction 15: Milton Malsor CP

Roade: Roade CP in the north; Stoke Bruerne CP in the south

Topography Mostly flat, slight undulations

Current Land Use Arable, pasture and horse grazing

Weather Sunny, dry

Geology Roade Bypass - Solid: Blisworth Limestone Formation – Limestone

across most of the area. Rutland Formation – mudstone across the

southern end of the site. Superficial: Oadby Member – diamicton across

the majority of the area.

Junction 15 – Solid: Whitby Mudstone Formation – mudstone.

Superficial: Oadby Member – diamicton across the site, with a small area

of mid Pleistocene Glaciofluvial Deposits – sand and gravel, in the north-

west corner (BGS 2017).

Soils Roade Bypass - Hanslope Association (411d) across the majority of the

area, with Denchworth Association (712b) across the south.

Junction 15 – Hanslope Association (411d) across most of the area, with

small area of Wick 1 Association (541r) in the north-west corner.

Hanslope soils comprise calcareous clayey soils, Denchworth soils

comprise clayey soils with similar fine loamy over clayey soils, and the


_________________________________________________________________________ 2


Wick 1 soils comprise coarse loamy and sandy soils, locally over gravel

(SSEW 1983).

Archaeology A search of Northamptonshire HER identifies several possible

enclosures and ditches within close proximity of the survey area(s), one

of which is located within the site itself (MNN125297), at the southern

extent of the survey area (Northamptonshire CC 2017).

Survey Methods Magnetometer survey (fluxgate gradiometer)

Study Area 64.8ha – approximately 0.8ha could not be surveyed due to livestock and

overgrown vegetation.

2.3 Aims and Objectives

To locate and characterise any anomalies of possible archaeological interest within the study

area.

3 METHODS, PROCESSING & PRESENTATION 3.1 Standards & Guidance

This report and all fieldwork have been conducted in accordance with the latest guidance

documents issued by Historic England (EH 2008) (then English Heritage) and the Chartered

Institute for Archaeologists (IfA 2002 & CIfA 2014).

3.2 Survey methods

Detailed magnetic survey was chosen as an efficient and effective method of locating

archaeological anomalies.

Technique Instrument Traverse Interval Sample Interval

Magnetometer Bartington Grad 601-2 1.0m 0.25m

More information regarding this technique is included in Appendix A

3.3 Data Processing

The following basic processing steps have been carried out on the data used in this report:

De-stripe

De-stagger

Interpolate

3.4 Presentation of results and interpretation

. The presentation of the results for each site involves a grey-scale plot of processed data.

Magnetic anomalies are identified, interpreted and plotted onto the ‘Interpretation’ drawings.

The minimally processed data are provided as a greyscale image in the Archive Data Folder

with an XY trace plot in CAD format. A CAD viewer is also provided.

When interpreting the results, several factors are taken into consideration, including the nature

of archaeological features being investigated and the local conditions at the site (geology,

pedology, topography etc.). Anomalies are categorised by their potential origin. Where


_________________________________________________________________________ 3


responses can be related to other existing evidence, the anomalies will be given specific

categories, such as: Abbey Wall or Roman Road. Where the interpretation is based largely on

the geophysical data, levels of confidence are implied, for example: Probable, or Possible

Archaeology. The former is used for a confident interpretation, based on anomaly definition

and/or other corroborative data such as cropmarks. Poor anomaly definition, a lack of clear

patterns to the responses and an absence of other supporting data reduces confidence, hence

the classification Possible.

4 RESULTS

The survey has been divided into 20 survey areas (Areas 1-20) and, where considered

appropriate, specific anomalies have been given numerical labels [1] [2] and these appear

in the text below, as well as on the Interpretation Figure(s).

4.1 Probable Archaeology

4.1.1 A positive, sub-rectangular anomaly, some 37m x30m in size, [1] has been identified in Area

17, and corresponds with the location of a cropmark visible on aerial photographs

(MNN125297) likely to be representative of a former enclosure, containing small discrete

responses which are likely to relate to backfilled pits. To the north-west of the enclosure

further linear anomalies [2] have been detected. These are indicative of cut features and may

relate to a larger enclosure / field system associated with [1], and form part of one area of

settlement.

4.1.2 A weak, sub-rectangular and linear anomaly [3] has been detected in Area 3. This is

indicative of a small former enclosure and boundary ditch. Also in Area 3, to the north of

anomaly [3], a weak curvilinear response [4] has been identified. This is likely to relate to a

larger enclosure, though the full extent of the response cannot be determined. These

responses are likely to be a result of a further area of prehistoric settlement activity.

4.1.3 The morphology of all of the probable archaeological responses detected indicates that they

are likely to have a late prehistoric origin.

4.2 Possible Archaeology

4.2.1 A number of small discrete responses and an area of increased response [5] can be seen in

Area 17. These may relate to small backfilled pits or areas of industrial activitiy. Their

proximity to a sub-rectangular enclosure and ditches [1-2] indicates that they may be related

to this, though their exact origin cannot be determined with confidence. These provide further

evidence of settlement activity in the area.

4.2.2 A band of enhanced magnetic response [6] runs from the cut features in the north of Area

17, towards the sub-rectangular enclosure [1]. This may be related to a former boundary

ditch, though the strength of the response suggests it may have a natural origin.

4.2.3 Positive, parallel linear anomalies [7] in Area 16 may be associated with a former trackway,

possibly associated with the settlement evidence to the south. However, it is also possible

that the features are an agricultural effect, especially given that the ridge and furrow

cultivation detected across the area follows the same alignment.

4.2.4 Further weak linear and curvilinear anomalies have been detected in Areas 1, 4, 16 and 17.

These may be related to former cut features, such as ditches, though their lack of context


_________________________________________________________________________ 4


and weak response makes further interpretation difficult. It is equally possible that they are a

result of agricultural activity, i.e. field boundaries.

4.3 Former Field Boundary

4.3.1 Positive linear anomalies [8-9], corresponding with the locations of former field boundaries,

have been detected in Areas 6 and 17. Both of the boundaries are visible on available historic

mapping from 1884 to 1993.

4.3.2 An area of enhanced magnetic response in Area 11 also corresponds with the location of a

former field boundary, visible on available mapping from 1884 to 1990.

4.3.3 A positive linear anomaly [10] running roughly east-west in Area 10 may relate to a former

field boundary, but is not visible on available mapping.

4.4 Agricultural – Ploughing, Land Drains, Trackways

4.4.1 Widely spaced, parallel linear anomalies are visible in Areas 1-4, 8, 11-12 and 16-18; they

are a result of ridge and furrow cultivation.

4.4.2 Evidence of modern ploughing is visible in Areas 1, 5-6 and 7-9, in the form of magnetically

weak, closely spaced, parallel linear anomalies.

4.4.3 Strong magnetic linear anomalies are visible in Areas 5 and 18. These are related to modern

farm tracks, visible on aerial photographs and modern mapping.

4.4.4 Magnetically weak linear anomalies in Area 8, and strong positive linear anomalies with

associated negative responses in Area 5 are likely to be related to land drains.

4.5 Natural / Geological / Pedological / Topographic

4.5.1 Several areas of sinuous and amorphous magnetic variation have been detected across the

site (Areas 1-3, 10, 12-13 and 17-18). These are typical of natural responses detected across

superficial deposits of diamicton.

4.6 Uncertain

4.6.1 Several positive linear and small discrete responses are visible across the site. These may

be archaeological, agricultural or natural in origin. The anomalies do not form clear features,

and many provide weak responses, hence their classification as being of ‘uncertain’ origin.

4.6.2 A large area of strong magnetic debris [11] in Area 1 also falls into this category. The strength

and nature of the response suggests that it has a modern origin, and may relate to an area

of made ground. Similar responses are detected over infilled ponds/gravel pits, however

there is no evidence for any such feature in this location on available historic mapping.

4.6.3 Areas of increased magnetic response [12] have been detected in the north of Area 16. It is

possible that these are associated with the archaeological remains to the south; however,

the are thought more likely to be of modern or agricultural origin.

4.7 Ferrous / Magnetic Disturbance

4.7.1 Strong bipolar linear anomalies in Areas 5 and 6 are related to underground services, such

as pipes or cables.


_________________________________________________________________________ 5


4.7.2 Areas of weak scattered magnetic debris are visible in Areas 1, 3, 3, 6-7 and 10. These are

of modern origin, and likely relate to ferrous debris/rubbish within the topsoil.

4.7.3 Ferrous responses close to boundaries are due to adjacent fences and gates. Smaller scale

ferrous anomalies ("iron spikes") are present throughout the data and their form is best

illustrated in the XY trace plots. These responses are characteristic of small pieces of ferrous

debris (or brick / tile) in the topsoil and are commonly assigned a modern origin. Only the

most prominent of these are highlighted on the interpretation diagram.

5 DATA APPRAISAL & CONFIDENCE ASSESSMENT

5.1 Heritage England guidelines (EH 2008) Table 4 states that the typical magnetic response on

limestone is good, however over mudstone and diamicton results can be variable. The

detection of areas of prehistoric settlement activity along with further linear anomalies and

enclosures, suggests that this survey is likely to have detected any archaeological features,

where present.

6 CONCLUSION

6.1 The survey at Roade and Junction 15 of the M1 has identified two areas of likely prehistoric

settlement activity, comprising a sub-rectangular enclosure, linear anomalies and small

discrete responses. An area of possible industrial activity has also been detected, though it

is possible that this is modern in origin.

Evidence of ridge and furrow, former field boundaries and modern ploughing across much of

the area indicate that the site has a largely agricultural past.

Areas of magnetic debris and disturbance are a result of nearby ferrous metal objects, such

as fences and underground services.

Appendix A - Technical Information: Magnetometer Survey Method Grid Positioning For hand held gradiometers the location of the survey grids has been plotted together with the referencing information. Grids were set out using a Trimble R8 Real Time Kinematic (RTK) VRS Now GNSS GPS system. An RTK GPS (Real-time Kinematic Global Positioning System) can locate a point on the ground to a far greater accuracy than a standard GPS unit. A standard GPS suffers from errors created by satellite orbit errors, clock errors and atmospheric interference, resulting in an accuracy of 5m-10m. An RTK system uses a single base station receiver and a number of mobile units. The base station re-broadcasts the phase of the carrier it measured, and the mobile units compare their own phase measurements with those they received from the base station. This results in an accuracy of around 0.01m.

Technique Instrument Traverse Interval Sample Interval

Magnetometer Bartington Grad 601-2 1m 0.25m

Instrumentation: Bartington Grad 601-2 Bartington instruments operate in a gradiometer configuration which comprises fluxgate sensors mounted vertically, set 1.0m apart. The fluxgate gradiometer suppresses any diurnal or regional effects. The instruments are carried, or cart mounted, with the bottom sensor approximately 0.1-0.3m from the ground surface. At each survey station, the difference in the magnetic field between the two fluxgates is measured in nanoTesla (nT). The sensitivity of the instrument can be adjusted; for most archaeological surveys the most sensitive range (0.1nT) is used. Generally, features up to 1m deep may be detected by this method, though strongly magnetic objects may be visible at greater depths. The Bartington instrument can collect two lines of data per traverse with gradiometer units mounted laterally with a separation of 1.0m. The readings are logged consecutively into the data logger which in turn is daily down-loaded into a portable computer whilst on site. At the end of each site survey, data is

transferred to the office for processing and presentation. Data Processing Zero Mean Traverse

This process sets the background mean of each traverse within each grid to zero. The operation removes striping effects and edge discontinuities over the whole of the data set.

Step Correction (De-stagger)

When gradiometer data are collected in 'zig-zag' fashion, stepping errors can sometimes arise. These occur because of a slight difference in the speed of walking on the forward and reverse traverses. The result is a staggered effect in the data, which is particularly noticeable on linear anomalies. This process corrects these errors.

Display Greyscale/ Colourscale Plot

This format divides a given range of readings into a set number of classes. Each class is represented by a specific shade of grey, the intensity increasing with value. All values above the given range are allocated the same shade (maximum intensity); similarly, all values below the given range are represented by the minimum intensity shade. Similar plots can be produced in colour, either using a wide range of colours or by selecting two or three colours to represent positive and negative values. The assigned range (plotting levels) can be adjusted to emphasise different anomalies in the data-set.


Interpretation Categories

In certain circumstances (usually when there is corroborative evidence from desk-based or excavation

data) very specific interpretations can be assigned to magnetic anomalies (for example, Roman Road,

Wall, etc.) and where appropriate, such interpretations will be applied. The list below outlines the

generic categories commonly used in the interpretation of the results.

Archaeology / Probable Archaeology

This term is used when the form, nature and pattern of the responses are clearly or very probably archaeological and /or if corroborative evidence is available. These anomalies, whilst considered anthropogenic, could be of any age.

Possible Archaeology

These anomalies exhibit either weak signal strength and / or poor definition, or form incomplete archaeological patterns, thereby reducing the level of confidence in the interpretation. Although the archaeological interpretation is favoured, they may be the result of variable soil depth, plough damage or even aliasing as a result of data collection orientation.

Industrial / Burnt-Fired

Strong magnetic anomalies that, due to their shape and form or the context in which they are found, suggest the presence of kilns, ovens, corn dryers, metal-working areas or hearths. It should be noted that in many instances modern ferrous material can produce similar magnetic anomalies.

Former Field Boundary (probable & possible)

Anomalies that correspond to former boundaries indicated on historic mapping, or which are clearly a continuation of existing land divisions. Possible denotes less confidence where the anomaly may not be shown on historic mapping but nevertheless the anomaly displays all the characteristics of a field boundary.

Ridge & Furrow Parallel linear anomalies whose broad spacing suggests ridge and furrow cultivation. In some cases, the response may be the result of more recent agricultural activity.

Agriculture (ploughing)

Parallel linear anomalies or trends with a narrower spacing, sometimes aligned with existing boundaries, indicating more recent cultivation regimes.

Land Drain Weakly magnetic linear anomalies, quite often appearing in series forming parallel and herringbone patterns. Smaller drains may lead and empty into larger diameter pipes, which in turn usually lead to local streams and ponds. These are indicative of clay fired land drains.

Natural These responses form clear patterns in geographical zones where natural variations are known to produce significant magnetic distortions.

Magnetic Disturbance

Broad zones of strong dipolar anomalies, commonly found in places where modern ferrous or fired materials (e.g. brick rubble) are present. They are presumed to be modern.

Service Magnetically strong anomalies, usually forming linear features are indicative of ferrous pipes/cables. Sometimes other materials (e.g. pvc) or the fill of the trench can cause weaker magnetic responses which can be identified from their uniform linearity.

Ferrous This type of response is associated with ferrous material and may result from small items in the topsoil, larger buried objects such as pipes, or above ground features such as fence lines or pylons. Ferrous responses are usually regarded as modern. Individual burnt stones, fired bricks or igneous rocks can produce responses similar to ferrous material.

Uncertain Origin Anomalies which stand out from the background magnetic variation, yet whose form and lack of patterning gives little clue as to their origin. Often the characteristics and distribution of the responses straddle the categories of Possible Archaeology / Natural or (in the case of linear responses) Possible Archaeology /Agriculture; occasionally they are simply of an unusual form.

Where appropriate some anomalies will be further classified according to their form (positive or negative) and relative strength and coherence (trend: weak and poorly defined).


Appendix B - Technical Information: Magnetic Theory Detailed magnetic survey can be used to effectively define areas of past human activity by mapping spatial variation and contrast in the magnetic properties of soil, subsoil and bedrock. Although the changes in the magnetic field resulting from differing features in the soil are usually weak, changes as small as 0.1 nanoTeslas (nT) in an overall field strength of 48,000 (nT), can be accurately detected. Weakly magnetic iron minerals are always present within the soil and areas of enhancement relate to increases in magnetic susceptibility and permanently magnetised thermoremanent material. Magnetic susceptibility relates to the induced magnetism of a material when in the presence of a magnetic field. This magnetism can be considered as effectively permanent as it exists within the Earth’s magnetic field. Magnetic susceptibility can become enhanced due to burning and complex biological or fermentation processes. Thermoremanence is a permanent magnetism acquired by iron minerals that, after heating to a specific temperature known as the Curie Point, are effectively demagnetised followed by re-magnetisation by the Earth’s magnetic field on cooling. Thermoremanent archaeological features can include hearths and kilns; material such as brick and tile may be magnetised through the same process. Silting and deliberate infilling of ditches and pits with magnetically enhanced soil creates a relative contrast against the much lower levels of magnetism within the subsoil into which the feature is cut. Systematic mapping of magnetic anomalies will produce linear and discrete areas of enhancement allowing assessment and characterisation of subsurface features. Material such as subsoil and non-magnetic bedrock used to create former earthworks and walls may be mapped as areas of lower enhancement compared to surrounding soils. Magnetic survey is carried out using a fluxgate gradiometer which is a passive instrument consisting of two sensors mounted vertically 1m apart. The instrument is carried about 30cm above the ground surface and the top sensor measures the Earth’s magnetic field whilst the lower sensor measures the same field but is also more affected by any localised buried feature. The difference between the two sensors will relate to the strength of a magnetic field created by this feature, if no field is present the difference will be close to zero as the magnetic field measured by both sensors will be the same. Factors affecting the magnetic survey may include soil type, local geology, previous human activity and disturbance from modern services.
