Recent Archaeological Discoveries in South East Lancashire

Even on the moors, at 440 metres above sea level, many archaeological sites can be seen, several previously unrecorded.

I will list my recent discoveries in this blog. Most sites have been subsequently confirmed by other archaeologists and a geologist. Certainly much work needs to be done and detailed survey is urgently needed.

What’s new – June 2010

Detailed photographic survey of a site on Rooley Moor completed and magnetometer survey of another site (TBA) undertaken. Watch this blog for more details!

Video added! July

Sites missed

Great grass covered burial mound, near Rooley Moor, also missed amazingly.

The site below was missed in an earlier archaeological survey (oops!) and is man made and not a quarry or a mine, according to a British Geological Survey Geologist who kindly visited the site. Why not a quarry? not local stone! If the stones were quarried on the spot they would be “Haslingden Flags”. The number and orientation of the stones cannot be explained by glaciation. The difference in vegetation, visible in the photograph, may be why this area was chosen by whoever built this damaged, enigmatic site.

notches

Clear signs of working, note the two notches at the base of the stone.

This stone is clearly not from the immediate vicinity and so cannot be the result of quarrying at this location.

Here is another to the SW.

Bagden Hillocks Cairn

Still visible after thousands of years, the Bronze Age cairn (burial mound) at Bagden Hillocks. The area of the cairn is marked by the greener vegetation, the pile of stones in the centre is more recent.

Thanks to Bury Archaeology Group and Whitworth Historical Society regarding this cairn.

Lidar for your archaeological discoveries!

Lidar used to be exotic and expensive, but no longer! Cutting edge, archaeological  aerial survey techniques are now free for us to use.

Here is an example

Smallshaw_ditches_crop
Smallshaw, note the three ditches of the prehistoric enclosure and the image “shows” the ground  under the tree cover!

Here is a standard aerial view.

Lidar image bank

Get your Lidar images here

Example
The link example directs to OS grid reference SD 81, which covers most of west Rochdale.

The Ordnance Survey National Grid Reference System

See more about the OS grid reference system  here.

Selecting an OS grid square

Select a grid reference by entering the OS grid or move the map with your mouse or by touch.

SD81selected

Example
Enter SD81 to select the grid that covers west Rochdale.

Download and process your Lidar images

  1. Select the grid you are interested in (SD81 in our example).
  2. Create a directory on your pc, or other device for the group on files you download, example SD81
  3. Select a group of files to download  from the bottom of the display
    (the different file types and what they mean are explained here)
  4. Select DSM (in this example) at 1m resolution for SD81.
    SD81_DSM_at_1m
  5. The files are a zip archive of 180.3MB!
  6. Select the green download icon to download the zip archive.
    click2download.jpg
  7. Download the zip files to your directory (SD81 for example)
  8. Unzip the files with a compatible program (I used the free Pea zip, there are many others)
  9. You directory, with the unzipped files should look like these names, they are ASC file format.ascfiles
  10. These ASC files have to be converted into images you can view, use a GIS system if you have access to one (lucky you!), if not…go to step 11.
  11. To decode ASC files without a GIS system download the Relief Visualization Toolbox (RVT) for your operating system (currently supports Windows and Linux 64 ) from the Research Centre of the Slovenian Academy of Sciences and Arts.
  12. Download the RVT (for example rvt_1.1_win64 for Windows 7) and then unzip the files to a directory.
  13. Install the software, you should then see this
    IDL
  14. Select click to continue and then you will see
    reiefvistoolbox
  15. Select addfiles.jpg add the ASC files in your directory (SD81 in our example).
  16. Your directory should look like this:
    SD81DSM1ASCfiles
  17. Load all the files and use the default settings for now and then select “Start”.
  18. This will take time depending on the speed of your computer.
  19. When the process is complete your directory should now have graphic files (TIFF format) created alongside the .ASC files.
  20. View these files with any program that can read and display the TIFF images, I used a free program called IrfanView.
  21. Here is a selection from one of the images, know what is in the centre? send me a message if you do please! -:) it’s old and it is north of Bury!

Want to install your own GIS system?

LandSerf is a free GIS system which runs on any platform that supports the Java Runtime Environment (Windows, MacOSX, Unix, Linux etc.)

Too much work?

Try this site, just zoom in to explore your region (some areas do not have Lidar coverage). Note you do not have the choice of surface or terrain Lidar images.

Thanks to…

Special thanks to Marcus Jecock of Historic England for telling me about the Lidar source files and the software to decode the ASC files.

The software to decode the Lidar source files is from Slovenia’s Institute of Anthropological and Spatial Studies and is funded by the EU, see more details here.

James Moran-Zietek for telling me about LandSerf.

Man Road Ditch

Looking south towards Man Road Ditch and Knowl Hill, Photo by David Mercer.

Even the name is mystery, “Man Road Ditch”. The ditch is of unknown date and unknown purpose and runs from the foot of Knowl Hill in a NNW direction.

The earliest reference found so far, is in the first series 6″ OS map (1851) of the area.

See the aerial view of the ditch hereNote select “satellite” to see an aerial photograph of the ditch.

Here is a Lidar view

The Third Castle!

There were three castle place-names mentioned in the 1626 Rochdale Manor  Survey, but I found the site before I knew of the reference to it.

Survey
We commissioned a geophysical survey and Al Oswald of English Heritage identified a strip lynchet  on one of the site’s steep slopes (west facing).

Location

It was not actually in Rochdale, it is in what was the old parish of….Middleton, in Ashworth township.

Geological summary

“Have looked at data we have on Copped Hill. I’m vaguely remember the
location. I’m pretty sure I never went to the top of the hill. Maps I
did at the time show it has melt water channels on western and southern
sides. The hill is capped by sand and gravel which would have provided
a better drained/dryer site if it was chosen as settlement location.”

Scout Moor Archaeology

Introduction – Under Construction…

This post will briefly cover the historical background to the area, (including the Forest of Rossendale) to better understand the context of the many archaeological sites in and around Scout Moor.

Exciting Discoveries

There are some exciting newly discovered sites to reveal. As in the case of the adjacent Rooley Moor, the area has never had a thorough archaeological survey, perhaps that is an understatement.

See for Yourself (from the comfort of your browser)

Select one of the links below to see sites of Farmsteads Fecit Lane and Coal Road: (centered on SD 81852 17717).

Medieval and other documentation for this area

The extensive body of medieval documentation for the area has been largely ignored by archaeological surveys of the area. This has been covered here.

Missed Sites

Some of the sites archaeological surveys of the adjacent areas have missed include:

  • A ruined medieval manor house (Naden Head) complete with earthworks and early wall
  • Several prehistoric burial sites, including a prominent site on Hunger Hill (see the picture at the beginning of this blog.)
  • Prehistoric Fields on Rooley Moor
  • Several early farmsteads, such as Birchen Holts

Cowpe

There was a vaccary (medieval cattle ranch) somewhere in Cowpe, location not yet verified.

Scout Moor lies mostly in what was the NW of Spotland, a township in the parish of Rochdale, and in what was Bury Parish.

Note
These are the historical areas (which were all in Lancashire), modern boundaries are very different; with the area now divided between Greater Manchester and Lancashire (Rossendale district).

British Geological Survey – Essential Data for Archaeological Surveys

Researching the geological context for your archaeological survey is essential.

The British Geological Survey (BGS) has hundreds of data sets to address the main questions a survey needs to answer;

  1. What processes (glaciation fault lines) led to the landscape you are exploring, how did this influence settlement patterns?
  2. Were mineral deposits (such as coal or iron ore) or quarry stone used in the area/period you are researching?
  3. How did soil formation effect (light soils sandy soils easier to plough )  land use?
  4. How  drainage/hydrology effect farming/fishing and transport routes.
  5. Will the surface geology effect geophysical survey surveys?

 

 

Game of Drones – Archaeological Aerial Photography by Quadcopter

A ‘game changer’, we are going to use a quadcopter to photograph existing, and reveal new medieval and earlier archaeological sites!

Jeff will be our pilot! He has already delivered outstanding views that show sites in a whole new light!

Where to start?

  • Get a base map of 1st series OS maps, National Library of Scotland have a fine site for this purpose.
  • Check the drift geology of the area (Geological Suvey)
  • See existing aerial photographs of areas of interest
  • Check for any old sites that are recorded but never photographed.
  • Use previously published criteria to locate special areas of interest.
  • Lidar photos may be available, check them is possible (English Heritage have some available)

Suitable Drones

Often called “quadcopters” if they have four motors, the most common format for affordable flying.

I will add to this list from time to time:

  • TBS Discovery used by guess who?!
  • DJI Phatom – a popular quadcopter for taking aerial photos
  • Quadcopters shop in UK – I have no connection with them, so for information only!

Take Off

Wow

Thanks to Jeff we have made significant discoveries, more soon!

Sidholme stone, Rochdale

Image

A curiosity, this one, a large stone beside a stream in Sidholme, north of Rochdale. The area is interesting with early enclosures and stone farmsteads nestling below the prominent Hunger Hill. I have posted two pictures, the first picture shows a rectangular recess cut into the south end of the stone. The second picture is taken from the other side of the stream, looking south east towards Hunger Hill.
