Breaking the silence with an article

Two years ago, during the summer and autumn of 2015 I worked on an article. I set an intention to account for and contextualize the Kvarnbo Hall based on the results of the investigations in 2014. I discussed the site and the building at the state of knowledge at that time in its regional and historical context, in comparison to the full data set of coeval houses on Åland. I also examined the development of Iron Age settlement and explanatorily discussed the rapid and large-scale colonization to Åland evident in the middle of the first millennium AD. As a result, a new perspective for our understanding of the emerging importance of Late Iron Age Åland was provided.

As the text turned out pretty well (if I might say so 😉 ), with lots of new knowledge potentially relevant beyond the Fennoscandian region, I decided to submit it to The Journal of Island & Coastal Archaeology, a well-renowned, peer-review journal rated high among archaeology journals worldwide. I was, of course, well aware of the fact that not only is it more difficult to get accepted in journals of such calibre, but that the wait time might turn out to be rather long. I submitted the manuscript on the 8th of December 2015. And I received positive reviews on the 1st of February 2016. My revisions were submitted on the 12th of February 2016. But then, the great silence spread its wings over the whole thing… (This silence was, however, apologetically explained by the editor during the summer). The processing of my manuscript was resumed in the beginning of 2017 and on the 7th of March 2017 it was finally published online. Why do I provide such a lengthy account on this process? To illustrate the anxiety the author is faced with?? Well, partially, yes, but also because things obviously changed during the excavation 2016 and certain aspects of this article written in 2015, the ones related to the building remains as seen from the infra-red aerial photo, should probably be reconsidered, at least, to a certain degree. In general though, I am very happy with this research being published and thereby providing some interesting stuff on the Late Iron Age settlement archaeology on Åland for a wide audience.

Reflections of a volunteer – part 6

by Anton Larsson

Anton as a front page teaser in the newspaper

Originally from the town of Uddevalla on the Swedish West Coast, I moved a few miles south to the “big city” Gothenburg three years ago to study archaeology. I recently took my Bachelor’s Degree there, so it seems to have gone quite well, and I’m just about to begin working towards my Master’s Degree. History and prehistory have always been my passion, and while my primary research interests have been quite different in the last few years, it was in fact the Baltic Iron Age which first caught my attention. At age four, I went with my family to Gotland, and was very excited by all the old Viking tombs, mainly beautifully preserved ship burials… and my parents bought me a wooden Dane axe-style toy. Big mistake. I kept running around screaming with it. Now, this summer, I returned to the Baltic Iron Age, although further to the north and with no axe.

I spent four full weeks at the Kvarnbo excavation, although it seemed almost like a lifetime – that’s probably because of the lack of WiFi and battery charging possibilities, though. I spent the four weeks at a campsite in Mariehamn, sleeping in a tent, which certainly took its toll. If it wasn’t for the magnificence of the project, if you pardon my hyperbole, I would have been complaining far more than I was doing. But a work experience so fulfilling and exciting can drive away the bothers of any living conditions, no matter how frugal. Although I have worked on prehistoric sites before, including one dating to the Vendel / Merovingian Era, there’s certainly no excavation in my short career so far that can match the one in Kvarnbo. Not only is it a fantastically fascinating place, with beautiful finds and ample knowledge to be uncovered, it has also been an excellent exercise in archaeological fieldwork. Although I did nothing during the four weeks that I technically haven’t done before, the work process has certainly opened my eyes to the uses and benefits of many strategies and technologies I have just barely considered before, including 3D-modelling, georeferencing, drone-based aerial photography, metal detecting, and plough layer digging. As I left the Åland Isles, that summery paradise (to tell you the truth, it was almost too summery sometimes, what with the nearly constant sunshine), I was filled with inspiration and new ideas for my future work.

Finally, something really must be said regarding the people of the excavation and of the Ålanders in general. Rarely have I ever been received as warmly as I was on Åland, or with such hospitality. Especially, the staff at the Kvarnbo dig – Kristin, Kim, Frands and Henke – were wonderful to work with, as were my fellow volunteers. No man can live on archaeology alone; such a lifestyle can only be sustained by the companionship of good colleagues.

The life of a post-hole

with Kim Darmark


Digging post-holes can be rather tedious, non-rewarding work. Cut through, photograph, document the section, take samples and on to the next one. To a certain extent, this has been true at Kvarnbo as well, but a surprising number of the post-hole remains have, on the contrary, been challenging and exciting to investigate. This is due partly to the fact that so many of them have a life history which is possible to reconstruct. It is often possible to follow the events that have taken place through the different constructional elements making up the feature. In quite a few cases, it is possible to see the edges of the original pit, filled with a lighter primary fill, which was deposited in the pit at the moment of its construction. This fill is often lined with stones, creating a solid base for a beam to rest on. Both naturally rounded stones from the surrounding and rugged, fire-cracked blocks of stone have been chosen for this purpose. The primary fill contrasts markedly from a darker secondary fill, which enters into the pit at a considerably later date, when the old supporting beam is removed from the pit. The darkening of the fill represents many years of intensive use of the site, during which large amounts of organic remains have been tossed on site, creating refuse layers, usually referred to as cultural layers. This dark soil only infills the small chamber that is produced by the stones in the stone packing, and is often also rich in finds, which constitutes the other interesting aspect of post-hole investigation at Kvarnbo. Since we sift the soil through sieving net using water, we find every little find, even tiny ribs, scales and vertebrae from fish, which has ended up in the post-hole. The usual finds are bones and pottery, but a few less common items have been found as well, such as pearls, and small copper loops. Almost every feature that has been investigated this season has contained at least a few finds, some of them large amounts, and gives testimony to the richness of the cultural layer once present at the site.

Reflections of a volunteer – part 5

My name is Kåre, and I had the pleasure of being a volunteer at the Kvarnbo Hall dig site. My background is not from archeology, but as a teacher in Norway.

I first heard about this project during a convention in Mariehamn, Åland, last year, where Kristin talked about the project and the local islands during the Viking age. I`ve always been interested in history, so when she informed about the possibility to volunteer, I thought this might be an interesting experience.

The excavation had already been going on for a few weeks before I arrived, but I was given a good introduction to the basic tools of the trade (trowel, bucket, hand shovel, measuring tape), and shown where and how to dig a proper hole in the ground, and how to wash, sift and sort the soil. It was also a new and interesting experience to learn what to look for. Especially, the fact that you could taste things, to feel the texture and hardness against your teeth. I haven’t put this many rocks in my mouth since kindergarten. Usually, I have to tell pupils in first grade not to put things from the ground in their mouth 🙂 To see and experience how much work that lies behind finding and sorting objects in the ground was an eye opener.

It was also very nice to work with the people who share a lot of the same interests. I don`t always get the opportunity to do this, since teachers are a very diverse group. I also found the tasks I was given interesting when I was told why it was done. Talking to, learning new things and getting to know the other people at the site made the work even more rewarding. I learned quite a lot from all of this.

The thing I found I had to work most with was to overcome my feeling of inexperience in the field, and my “Oh God, I`m going to destroy something if I do this wrong” – reflex. I think this made me a little hesitant at first, until I got my feet wet. Despite my inexperience in the field I felt I was included among the others at the site and made to feel welcome among everyone.

All in all I`m happy I volunteered for this, and hope to do it again sometime.

Traditional Strategy and New Techniques

by Frands Herschend

Strip (off the plough soil), map (the patterns you see) and sample (material from mapped structures) – is an archaeological field strategy applied to settlement remains in agricultural land, where crops have been growing for centuries. Ultimately, the method has become prolific, because of the gradual shift in the use of the cultural landscape. This shift made arable land more important and organized not least by means of roads. Consequently, farms were moved out of the farmland when possible. In Iron Age, on the other hand, arable land was less important, while grassland and meadows contributed substantially to subsistence. Not surprisingly, a rational Iron Age farm situation was in the centre of the farm’s agricultural area. Few roads were needed.

In Kvarnbo, change has been model, and today, the farms at Johannisberg are situated next to and above the arable land in which the Iron Age Kvarnbo hall stood on its small drained hillock.

When the excavations were planned, the strip, map and sample method was the obvious choice. But there are different way of stripping, mapping and sampling, and at Kvarnbo we have introduced a new mapping method in order to develop the general method. The testbed was successful during the test excavations in 2014, and in 2016, this mapping method was developed to become a routine.

Except for a handful of GPS reference points defining some of the test pits before the excavations started (see here), nine main reference points were defined after the top soil was stripped off in the area of over 1000 m2, and complemented with 183 reference points inside of that area. Supported by these, all (georeferenced) exact measurements, plans and sections are based on photographic 3D models. Also, a large scale plan was made with a drone during a 10 minute photo session and its orthographic projection, printed as an overview, has enabled the team to orientate itself on the site.

New techniques

Archaeological documentation goes hand in hand with interpretation. Description dominate fieldwork without excluding interpretation, and in the field, ocular observation is the general mode of perception: either you see something of you don’t. Later on, during the report writing process, interpretation and lab results dominate in order to answer the question: what cultural phenomena have we excavated? The problem in field archaeology is not what one observes, the problem is that which cannot be seen.

Overlapping features in the trench of 2014

In this section from the trial excavations of 2014, one can see archaeological features from Late Iron Age (A12 and A13) been transected by more modern plough furrow (A18).

For instance, looking at plough layer and plough furrows or any other depression, the point is to describe some sort of “ploughing biography” of the field as a part of the its involvement in history. It is easy to see the dark furrows when they cut into the yellow underground, but difficult to detect them at the bottom of the plough layer, and impossible higher up, although they may well exist in soil 20 centimeters or more below the surface. In fact, only by means of close observation of soil sections can one distinguish between ploughed and not ploughed soil.

Since we want to sample the contents of the different fills in postholes, we make a preliminary section of the first centimeters of the soil until, based on this section, we can dig away the plough soil, that is, the contamination of the prehistoric fill. As a result, we can, for example, conclude that the burnt clay, which represents burnt walls and was abound in the test pits, doesn’t exist in the postholes of the hall (because it was never burnt down).

So far, we have sectioned, described and interpreted c. 230 features of 273 on the c. 1000 m2 of our site. This is time consuming, but the ensuing 3D documentation is fast. On average, therefore, a team of four professional archaeologists and 2-3 amateurs can section, describe, interpret, sift and model 20-25 features per day, and sample soil for chemical and macrofossil analyses. 3D-modelling brings a new better and cheaper standard to strip, map and sample methods.
