More Bronze Age Pottery!

In a previous blog post, we shared our exciting pottery find from Trench 6 at the Kaims site: a single rim fragment of cord-impressed pottery with a tentative Bronze Age date.  In our 4th week of the season, a further 21 fragments turned up in the same area!  The find included two more rim pieces, four with cord impressions, and 17 undecorated fragments of various sizes from (we believe) the lower portion of the vessel.

After giving the collection a gentle wash, we were surprised to see that on the surface of several of the fragments are what appear to be small finger nail impressions running in horizontal lines in the fired clay.  They don’t appear to be intentional decoration, so they could be marks left by the vessel’s Bronze-Age creator during the forming process.  If after further analysis our suspicions are confirmed, this would be very exciting for us, because this find will be a rare glimpse of an individual person’s fingerprint on this landscape.

Pottery fragments after washing

When the new pottery was compared with the original fragment, we found that the three rim pieces fit together, along with the remaining two decorated pieces.  This gives us a much more reliable idea of the possible size of the vessel, which might have had a rim as wide as 45cm.  Right now we think we might have the remnants of a very large bowl or jar.

The 5 decorated pieces that fit together

One fragment revealed another feature of this vessel: a thin, raised band of clay running along the middle of the vessel, right at the bottom of the criss-cross, cord-impressed band of decoration near the rim.

Due to the poor quality of the clay and low firing temperatures, the vessel would not have successfully held liquid, but could have been used for food storage.

Amazing pottery from the Bradford Kaims

Last week we had a JCB at the Bradford Kaims to extend Trench 6. When cleaning this new extension, Project Officer Tom Gardner found one of the most exciting finds this site has ever seen: a large fragment of Bronze Age pottery. After giving it a wash, we discovered that the pottery was decorated with cord impressions making a criss-cross shape on its outer surface. The sherd is part of the pot’s rim, and thumb imprints can be seen where its creator was shaping it.

Although twisted cord impressions are common in Neolithic pottery, this sherd was found in a context that is likely contemporaneous with Bronze Age radiocarbon dates. Neolithic pottery is also extremely rare in the North East of England which led us to conclude that it was in fact Bronze Age.

Project Manager Rachel Brewer is currently doing an archaeological pottery drawing from the sherd to gauge how large the pot could have been, then it will be sent to our finds department for further analysis!

A Day at the Kaims – Part 1

The following is a report from my day at the Kaims… it’s taken me a while to get it posted.

Last week, I heard Matt Ross was looking for coring volunteers. I’d never done coring before and knew very little about the process or it’s archaeological potential. Keen to try my hand at something new and archaeologically relevant, I decided to take a day off Environmental and escape to the Kaims. After a week of rain, we had a day of sunshine and almost-blue skies. It was amazing. In the morning, they even let me have a go at trowelling in the west extension of Trench 42—it’s been so long since I’ve done actual archaeology. (I may have been a bit overzealous and taken out a few more stones than necessary… sorry, Graham).

Walking down to the trenches at the Kaims

To begin, I was extremely impressed with the archaeology at the Kaims. I, along with the other new students, got a site tour from Jackie, the Kaims Assistant Supervisor, first thing in the morning.

The last time I was at the Kaims, was in June 2011. Trench 6 had been opened and expanded to reveal a large burning area, possible hearth, and post-hole. Victorian era drainage pipes were being found and excavated. And the whole area didn’t look like a bog, though I admit to having to stand in a few inches of water to attempt a section drawing.

This is what it looked like when excavation of the Kaims began in 2010.

What a typical trench at the Kaims used to look like – a 1 m x 2 m rectangle.

What we once thought was interesting archaeology

This is the Kaims now. That’s progress.

Community diggers excavating Trench 6 in the off-season

The archaeological features that have appeared this season are enough to satisfy the appetite of all you prehistoric archaeologists–a burnt mound reminiscent of others found across the UK and Ireland and what was originally hoped was a cist burial.

Recent theories as to origins/purpose of the burnt mound and surrounding area: cist burial , beer production site, fish drying site, tanning site, sweat lodge, cooking area.

An extension was made to the east of trench 42 to allow for a pit to be dug to explore the theory that the large worked stone that was uncovered in T42 might be a stone slab/head stone of a Bronze Age cist burial.

The extention has revealed one edge of the burnt-stones area, but as of yet, there is no compelling evidence of a burial in that direction. Could it possibly be under the stones to the west?

When I was up there on Friday, Sarah Aguirre was continuing the excavation of the long, thin sondage/test pit in the east quadrant of T42—next to the stone slab. The work revealed a series of stones, but no burial as originally hoped.

Meanwhile, Eva Rankmore was excavating a pit feature in the northern part of the trench. As of yet, it’s unclear whether the pit is natural or man made, though the most recent (and mostly likely) theory is that it’s a tree throw.

Nearby, in the area to the SE of T42, students new to the Kaims were taught how to set up and excavate test pits in the hopes of uncovering the cluster of possible burials. As of today (Thurs. July 19), 10 new test pits have been put in, and nothing particularly archaeologically exciting had been uncovered. However, two of the test pits did reveal a continuation of the modern (Victorian era) drainage feature, evident—although the terracotta pipes had been removed at some point—in the south end of T42.

Opening test pits and new trenches at the Kaims

Other than excavating what I feel is some very promising/intriguing archaeological features, a number of interesting finds have also been found this season – A piece of prehistoric (Bronze Age?) ceramic. A beautiful little flint point (likely an arrowhead). A lot of what is believed to be un-worked jet.

That was somewhat my morning at the Kaims. I hope you enjoyed it. Tomorrow’s blog post will continue my insider’s view of a day at the Kaims, accompanied by a more technical explanation of the coring process provided by Matt Ross. A more detailed summary of this season’s work at the Kaims will also be forthcoming.

If any of you readers have any questions for the Kaim-anites about any of the archaeology or finds coming out, feel free to post to the blog or our facebook page. We’re more than happy to answer your questions to the best of our abilities.
