The Saga Continues ...

Good news for all those who have been following this blog - the digging has started for 2009!

I have recommenced the pit I left open in 2008 at level 8. As well as very quickly turning up pieces of Iron Age pottery I made a momentous find - my first substantial piece of verdigris coated metal. It isn't much to look at but it is a first. I have spotted the tell-tale green signs before but they have crumbled to nothing. This time the chunk stayed in one piece - see photo above.

I have toyed with the idea of filling this pit in and not continuing but I have resisted on the basis that something of significance might be lurking in it. We will see ...

A Talk and a Nodule

I have just given a talk to a neighbouring Local History Group on the subject of Back Garden Archaeology. It went reasonably well considering it was touch and go whether I’d be able to do it due to a sore throat and loss of voice. My voice held out in the end. To give me strength on the day I told myself that I had volunteered to talk, it was on a topic that I enjoyed and that I wanted to do it.

There were questions and comments at the end that were encouraging. Someone asked if the stone of the pot-boilers was local and when I said it wasn’t they suggested that it had come from the coast because of its sea-tossed smoothness. Someone else suggested it could be more local than the coast and glacial in formation. All of which indicates a line of research if I can find an informative geologist somewhere.

There was some interest in the examples of slag that I had taken along. No one seemed to know if it should show signs of a metal reaction under a metal detector and anyway I had discovered that not all slag is the result of metal working anyway. So, what form of industry do the examples I have unearthed suggest? That is another line of inquiry.

I said during the talk that I had not found anything made of metal of any significance and that no worked flint had appeared. There is just one item that makes me reconsider this but I didn't mention it. It is a flint nodule of a very comfortable hand-shaped size (see the photos) that seems to be pock-marked with chips added to which it has a pointy side and a hemispherical side. I wonder whether it is natural or a tool of some kind. It is not that I am desperate to find a significant piece of flint but it would be nice considering how much has been tossed on the spoil heap.

The Snails Are Back!

Just in case you can't see what this is - it's a snail shell.

I am 70 to 80cm down and shells like this have started to appear. I am encouraged to find them as they mean that the soil I am going through was on the surface at one time. Either the snails were part of infill or they got into the ditch as it was filling up. Judging by the nature of the soil it seems like the former. In previous digs I have seen the layers that have built up in the ditch as fine dark soil. What I am going through is very coarse with a lot of chalk and flint so it could be late Iron Age infill.

A New Start

After weeks of rainy days I have returned to my neglected dig. I decided to shore the sides up before continuing as they looked unsafe. That way I can leave things open over the winter if I can't get to the bottom before the weather closes in.

How do the professionals cope with adverse weather conditions?

I am just going into level 7. Compared with previous digs into the same ditch feature (only a foot or two away) I am finding fewer sherds of pottery and animal bones, so far, but I am prepared to be surprised.

I am beginning to think that the first test pit I sunk into this feature uncovered the area that was open longest and got filled up with the most Iron Age domestic waste (lots of animal bone, pottery, pot-boilers).

Unexpected Help

I am still continuing with my dig although I have been hindered by bad weather and other demands on my time. Recently, after a prolonged period of rain, I looked in the pit and saw that I'd had help! A hedgehog had wandered in and could not get out. Over a period of days it had scratched away at the sides in an attempt to escape. Luckily I managed to lift it out in time and initially it looked exhausted but when I started up the lawn mower to cut adjacent grass it uncurled and fled. I now leave a hedgehog escape ramp in the pit when I am rained off.

Latest Finds by Level

This photo gives some idea of what has been found in the latest dig so far. I've kept more than I normally would in order to show others what to look out for. Sometimes what looks like a piece of rock turns out to be pottery and vice versa.

The oldest, most interesting pottery sherds are on the far left. Later medieval and modern pieces are further over to the right in the pottery column.

I have been keeping natural geological specimens other than white chalk and smaller pieces of flint. Some of these are distinctive and not like anything I've found before. Which is why I need a geologist as well as a pottery expert to consult! In layer 5 I have just started to find pieces of what look like broken pot-boilers (see a previous post).

In the bottom left corner I have encircled 5 pieces of the late Iron Age pottery which started to emerge at level 4.

A Post Hole

I've got a post hole to excavate in this dig. This shows it carrying on down from the 40 cm level. It seems to be about 72 cms deep from the current ground surface. What I have removed seems to reveal just the hole created by the post. The hole to take the post was dug wider I think. Finds in the hole suggest a relatively recent date. Since this photo was taken and the hole has been widened I have found a piece of clear glass that looks fairly modern.

Removing the top surface of level 5 has revealed a change in soil type. I have come to a fairly poor soil, lacking in humus with a higher chalk content. At a guess I'd say that I am just going below the medieval cultivated surface. It is after this that things should get more interesting. We will see!

It always surprises me ...

I have just cleared level 4. I've said before that I always find at least one piece of Iron Age pottery at level 4. I was beginning to wonder whether I was right about that. I was washing my last tray of finds and amazingly the very last piece of pottery I washed turned out to be the same as the "local coarse ware" I've seen so many times before - an indication that I am travelling back in time and getting closer to the levels that contain evidence of the late Iron Age.

Pause for Thought

There are two reasons I haven't been digging in the back garden recently. One is that I had to take a break because of my daughter's wedding, the other is that I have been on an archaeology course for a week. With other volunteers, on a major urban dig, I learnt about the theory and practice of professional archaeology.

I was lucky enough to be able to attend for free as the course was part of a Community Archaeology initiative. Instruction and supervision were outstanding. I have to admit that it was a surprise to find that digging was a minor part of the course with the emphasis being to learn about the methods employed on and off site to fully record what is uncovered. In hindsight I see the sense of that. Reading about archaeology had not prepared me for the rigorousness of the actual practice.

I have dual interests, one for my personal efforts and the other for initiatives within the wider area of the parish in association with a local history group. I need to mull it all over ......

I find myself mulling over the significance to me of single-context recording, the hand-drawing of contexts and the relevance of the matrix to my efforts in the back garden.

Hopefully I won't be mesmerised into inactivity .....

One Iron Age Sherd

The only type of pottery I can reliably identify, because of the guidance of experts, is late Iron Age "local coarse ware". It is good to have at least one point of reference.

The photo above shows the latest single piece from Test Pit 2. It was found at level 4, which is normally the case. It is a rim piece that I've scanned to show the colour and nature of the fabric with its white inclusions.

I've no doubt that the presence of this type of pottery represents late Iron Age settlement in the immediate vicinity. The presence of copious amounts of this type of pottery in a previous dig, below, alongside and above pottery from the Roman era, suggest a continuation of use of the coarse ware either side of Romanisation.

Test Pit 2 - Closed!

I haven't been keeping up with events! Test Pit 2 petered out at around 40 cm. I scraped the bottom, measured the depth and then filled it in (and sowed some grass seed on the top).

The pottery finds are laid out above. Level 4 included some older looking pieces, including the largest piece (top right) which was of a colour and fabric I haven't seen before. More about that later.

One piece missing from the photo is a single rim-piece of "local coarse ware". It is identical in colour and fabric to my other late Iron Age pieces (see following entry). So, true to form, I always find at least one piece of this type wherever I dig in the garden.

The piece I featured in my previous entry seems similar in fabric (and inclusions) to two pieces of a gritty nature that have a green glazed finish. Although these have signs of a grey core, the fact that they appear to have the same brown pebbly inclusions makes me think that they are related. I thought that the orange piece I wrote about last might be older than this.

Oh for a pottery expert I can run to with such things!

Test Pit 2

I've started on Test Pit 2! The photo above shows the location: at the bottom of the garden. Beyond the hedge is a back lane. On the other side of that were the open fields before enclosure in 1772.

I said that I expected the same range of pottery only less. One of the first pieces I uncovered was of a type I haven't seen before - see below:

The outside (convex) surface is slightly darker than the inside (concave) surface though not quite as much as this scan suggests. The fabric is the same orange colour all the way through. The inclusions are interesting:

They are of two types: very minute, dark brown, pebble-like and smooth (on the left above); again minute, quartz-like, white/translucent (on the right).

The inside has two, not quite parallel, lines about 1.5 cms apart. Evidence of a tool used for smoothing, perhaps?

This piece was at level 1 (in the first 10 cms). I normally riddle the first two levels but I decided to trowel instead this time. I am glad I did!

I am quite excited about this piece for some reason!

Bereft of Finds!

I have packaged up my finds to date and taken them to a local museum for any possible help that is available to identify pottery types and dates.

What with that and catching up on assembling photographs and documentation from previous digs I have had my head down and I have not been able to open another test pit.

But I have got a location in the garden staked out ready. As it is further down the garden it means that it is more than likely to be in an area that has been continuously cultivated for centuries. I predict that I will find the same cross section of pottery but less of it. But I could be wrong. We will see.

More and more, the idea of community test-pitting as an organised event appeals to me, if only for the chance of being able to engage the necessary archaeological expertise. Having to go out and find that expertise as an individual is not easy.

I have tentatively started to ask others in the village if they would be willing to be involved by making a part of their garden available.

CORS & HEFA

I have been lent the Annual Report (No. 20) of the Medieval Settlement Research Group for 2005. It couldn't have come at a better time.

Low and behold, there is a paper by Carenza Lewis entitled, "Test pit excavation within occupied settlements in East Anglia in 2005" which "introduces a new project which is focussing on the archaeological investigation of medieval rural settlements that are still inhabited".

I am pleasantly surprised to see that a new (to me) acronym of CORS has been devised for "currently-occupied rural settlements". With CORS it would seem, test pits have become main stream and the verb "test pitting" has arrived.

The project described is tied in with the Higher Education Field Academy (HEFA - find out more here) thereby meeting twin archaeological and educational aims (and providing an archaeological workforce in the process).

The paper concludes, "In terms of archaeological results, it seems clear already that the HEFA model of test pit excavation within currently-occupied rural settlements can and does produce new and useful archaeological evidence".

How encouraging! Somehow I feel less confined to the periphery of archaeology. But it does make me want to catch up with the documentation of my test pitting!

Regrouping

The village I live in is called a "nucleated settlement" with dwellings concentrated at one spot in the landscape and formerly surrounded by the Open Fields. The experts say that prior to this dwellings were dispersed over the landscape. So, when did nucleation begin? Also, there are signs that the village layout was replanned at some time in the past to give it a more regular appearance. When did this happen? I started to dig in the back garden in order to answer these questions ...

... and I have decided that answering these questions is more important, at the moment, than finding the end or the continuation of the Iron Age ditch. Finding pottery (or anything else) provides a chance of obtaining dating evidence for continuous habitation on this plot of land. That could help with the nucleation question if not the one of replanning.

After I've documented the current dig and packaged the finds so that I can obtain expert advice on type and date, I plan to open a test pit at the bottom end of the garden in order to explore something completely different!

Rock Bottom!

As I trowelled off the surface of layer 6 I realised that I was seeing the natural sub-soil, a light brown mixture of pieces of chalk and clay. Bad news!

For anyone who hasn't read the earlier posts I was hoping to find the continuation of a ditch feature running into the garden from the boundary. The diagram below (not to scale) shows the location of previous digs, the possible direction of the ditch feature and the test pit I have been working on in 2007.


So, I have to conclude, at least, that the ditch doesn't run in a straight line. Tantalisingly the natural surface slopes off towards the edge of the test pit (on the boundary side). Does the ditch continue but not in a straight line? Or, perhaps it isn't a ditch at all. It could be a hole dug for some practical purpose like the acquisition of clay.

Watching Time Team prepares you for such set backs! I will have to regroup, consult the "Mick Aston" within and decide how to proceed.

In the meantime, the grass needs cutting!

Wild Speculation

I have learnt that it doesn't pay to speculate on what type and date a piece of pottery might be. But that doesn't stop me doing it!


In looking through the reference books I have to hand (I have listed them in the sidebar) this sherd seems closest to a Stamford ware crucible judging by the shape of the rim (from the A. J. Mainman book). There is a deposit on the outside of the sherd that could result from use in extreme heat. But this is wild speculation!

Although I show the sherd in cross section I do not think I have got its inclination right. It probably sloped inwards on the actual vessel.


I will not attempt to guess at this one but it does have a distinctive rim shape (like the top part of the Times Roman number "1"). I am hopeful that this, with the colour and type of fabric, will enable an expert to give it a date.

My first stop for dating will be the regional Portable Antiquities Scheme. This time instead of taking along a few pieces at a time I will take everything from the one dig and leave it for identification (if they will have it!).

Level 5: The Outcome

Just one or two observations before I feature some specific pieces in a later entry: a small number of bone fragments are on the right and beneath them is an encrusted nail-like object (which I wouldn't normally bother with but it is quite long and slender); the majority of the sherds are unglazed; of the glazed pieces there is one that is splash glazed, one fully olive-green glazed and one partially dark green glazed with grey fabric.

In the centre of the display, the largest sherd is exciting! It has signs of finger indentations at two of its tips with accompanying fingerprints. It is quite flat so I cannot make out what kind of artefact it comes from.

I think that the pieces come from a range of eras but I don't want to prejudge the expert opinion.

And there were Bones ...

When I found the pot-boilers I also found a mass of animal bones. Although I am still finding the odd bit of bone in other digs in the garden there is nothing like the same amount.

The photo shows the accumulation of bones from two previous digs that explored the Iron Age ditch feature. Along the bottom there are an array of animal teeth and bits of jaw bone. The biggest bone in the photo was found 1.1 metres down. As the pottery found at this level and lower was crisply broken and not worn it is fair to assume that all of this domestic debris was discarded close to where it was used.

By contrast, my current dig is further down the garden and although I am finding pottery and bone it would appear that it has been much disturbed by cultivation.

Stop press: I have cleared level 5 and I am starting on level 6. More about that later.

Talking of "pot-boilers" ...

The photograph shows the quantity of "pot-boilers" I found when excavating the Iron Age ditch feature in previous years. At the time it didn't seem unusual but when you carry on digging elsewhere and find none of them you get a better perspective. On Time Team they get excited when they find one!

Apart from one or two examples of whole, smooth, small stones, all the rest show signs of being pieces that have cracked away from larger, smooth stones due to thermal shock.

The quantity seems to indicate use and disposal over time. The ditch they were found in showed signs of having gradually filled up.
