2013 Day of Archaeology Festival Thank You!

The D.C. Historic Preservation Office (DC HPO) would like to thank everyone who came out and supported the 2013 Day of Archaeology Festival!  Thank you for stopping by our table and participating in our activities, we really enjoyed having you.   We would also like to thank Archaeology in the Community, for hosting the D.C. festival. 

It was a very successful event!

For those of you who wish to learn more about the DC HPO, within the Office of Planning, please navigate to our website.

The DC HPO presented on Prehistoric Pottery and Historic Ceramic assemblages, found in DC archaeological sites.  Displays were complete with signage and artifacts.  Visitors were engaged in a variety of activities, such as the “What is This?” game, where visitors had to guess the identity and function of artifacts on display.  The Stratigraphy Exercise, where visitors matched artifacts to associated soil contexts.  And, finally, the Pinch Pot making station, where visitors make their own clay Pinch Pots using prehistoric-themed tools and techniques.  It was a huge hit with the kids!

Tracing Neandertal Territories in the Mountains of Southeast France

Day of Archaeology 2013 for me means being away on 2 months of fieldwork in the southern Massif Central, France.  I’ve been contributing to DOA since 2011, and if you look back, it’s clear a lot has changed  since then (see my four 2011 posts, and 2012). After my PhD I was searching for a postdoc for several years, ran out of time and money to keep looking, and ended up seredipitously with a contract to write a book about humans and birds in prehistory.

I thought that would be it, and that the 2013 Day of Archaeology would take place without a contribution from me. But it seems that archaeology wasn’t quite done with me…

As I wrote in a postscript comment to my post last year, only a few days after writing about the difficult process of changing paths from a research career to one focused on writing and wider communication, an email dropped into my inbox from the European Commission offering the very last postdoc funding I applied for- a Marie Curie Intra European Fellowship to work in at the PACEA lab, Universite of Bordeaux. After a lot of soul-searching on the wisdom of doing another 180 degree turn in my life trajectory, and talking with my husband about him coming out with me, I decided to go for it. And so here I am, in the mountains of the Massif Central!

My postdoc is focused on two elements: training in a new skill (the Marie Curie Fellowships are especially concerned with career development), and applying this method to an archaeological context. I’ve written on my own blog in more detail about my project, which is called TRACETERRE. This stands for “Tracing Neandertal Territories: Landscape Organisation and Stone Resource Management“. It’s part of a larger collaborative project directed by my boss, Jean-Paul Raynal, and Marie-Helene Moncel.

Essentially I’ll be learning a detailed geological technique called petro-archaeology, that allows us to determine where in the landscape Neandertals were obtaining the raw materials to make their stone tools. Specifically, we are especially interested in the flint sources: most of the geology in the area is igneous, which means it comes from volcanic action (the Massif Central is a world famous centre for volcanology, where you can see virtually every type of volcano and lava).

It’s possible to make stone tools from these kinds of rocks, but they are often very hard, and can also be coarse. Flint is a sedimentary rock, meaning it forms from the slow accumulation of mineral deposits. Flint is famous for the high quality tools that can be made from it, because of the predictable way it fractures. It’s often associated with Cretaceous chalk deposits, such as the big cliffs in the southern UK, where you can see black bands of flint nodules. So flint forms in marine contexts, but it can also form in other situations such as in lakes.
Although there are few primary sources of flint in the Massif Central (i.e. outcrops of rock containing flint), there are many different secondary sources. These can be eroded outcrops, material washed into river gravels and other kinds of sources. My training will be in identifying these secondary types of sources, based on the way the outer surface of flint cobbles changes during the process of first formation, erosion and later exposure at archaeological sites.

Because there are more than 70 different secondary sources in the region which have been painstakingly identified over more than thirty years (by Paul Fernandes, who will train me), this is too much to try to attempt to learn in two years. So I will be using a source-centred approach, where I look at one flint source, and see how this particular rock has been used by Neandertals. In particular, we are interested in where this rock ends up: which caves or open-air archaeological sites is it found in? And secondly, in what form does it occur: as finished tools, raw blocks, or flakes of stone that have been struck off blocks (cores) but not yet made into tools.

Finding these things out can tell us a huge amount about techno-economics: the way in which Neandertals were choosing to organise their exploitation of resources on landscape scales. For example, working out which types of technology they used to make tools and which stages of tool production occur where can reveal the level of investment of energy: were they making tools quickly, and dropping them soon afterwards? Or were they carefully choosing which kinds of tools to make, and which ones to take with them in toolkits, maintaining them by re-sharpening? Both these strategies can be used as adaptations to different situations, particularly the level of mobility.

A handaxe, one type of tool Neandertals seem to have carried with them as part of mobile toolkits, which could be re-sharpened and used in many tasks. This one is from near Bournemouth, UK

The question of Neandertal mobility is also a key reason for studying in such detail the different sources of stone used. We want to know where the stone from a flint source was going: which sites is it found in? How far was flint being transported, especially in comparison to other stone types? We can even begin to work out the paths taken through the landscape by Neandertals: did they have to cross rivers, high mountainous areas? Which passes would have been likely to be used? We also plan to excavate at the flint source itself, to see what activities were taking place, and also which tools came from other places in the landscape.

We can then begin, by combining all the geological and techno-economic data, to build up a detailed understanding of the inter-connections between different parts of the landscape that Neandertals were living in. And this is just the stone tools: other parts of the archaeological record, such as animal bones preserved in caves, are studied by other project members. We can use these to determine things like what season people were living at sites, and where they were probably hunting the animals in the landscape.

All this creates a web of the palaeo-landscapes that Neandertals were inhabiting. But the impact of sourcing flint tools goes even further, because if we can map the extent of inhabited landscapes, we can start to think about territories. This is crucial because territories are not just regions full of resources- they probably were also involved in defining social interactions between different Neandertal groups. This is something we are still learning how to measure, but it has huge significance because different kinds of territories and social interactions suggests particular cognitive capacities. This is of course one of the key areas of research in human evolution: how did Neandertals differ from us, and how were they similar? Did they have similar webs of social connections, or were they living local, isolated lives in small groups that did not regularly meet? If this was the case, how did they find mates, and prevent huge in-breeding? All these fundamental questions can be advanced by new data and investigations such as the research I am doing.

Right now, I’ve only been here just over a week, and am only one month into a two year postdoc. So there’s a long way left to go. But it’s very exciting, and I hope to start the petro-archaeology training and looking at the flint collections very soon. Meanwhile, there’s always time on fieldwork to have a day off, check out the local wildlife, cuisine and culture, and enjoy some of the lovely sunsets in this region. Very different landscapes to when Neandertals were living here!
