Some Quick Notes on Intensive Survey Method in the Argolid

This weekend I finally got around to putting together my various notes from database and GIS crunching and field observation on the Western Argolid Regional Project. Since we’re still working to analyze finds from this season, our main body of data derives from artifact densities. That being said, we have been able to spend a little time figuring out what variables had the greatest influence on artifact recovery throughout the survey area.

FEET

Visibility. The overall visibility in the survey area was right around 50%. Surface visibility did not correspond with artifact densities in a linear way, as survey archaeologists have come to expect. The highest artifact densities peaked first in units with 50% visibility and then in units with 70%—90% densities before dropping off in units with 100% artifact densities. In fact, units with 100% visibility produced fewer artifacts per ha then the average for all units. This serves as a useful reminder that visibility and artifact densities are independent variables even if the drop in density at 100% visibility hints that something strange must occur to artifact recovery rates in fields which have been finely plowed and cleared of all vegetation.

Surface Clast Size. We also recorded surface clast size for each field. Most of our fields consisted of 19-75 mm coarse gravel and these fields along with those with cobble sized (>75 mm) surface clast produced the highest densities. The average visibility in these fields falls between 41% and 53% respectively. Cobbles tended to produce more artifacts per ha than average visibility alone might suggest, but not by a vast margin (1040 artifacts per ha rather than the 913 artifact per ha that units with 50% visibility tend to produce). Units with coarse gravel were consistent with visibilities. Interestingly, units with fine gravel or sandy soil produced fewer artifacts than their average visibilities would suggest. Sandy soils, although relatively rare, had 41% visibility but produced only 390 artifacts per ha. It’s tempting to see sandy soils as recently deposited riverine sediments, but they don’t necessarily pattern that way across the survey area.

Background Disturbance. Recently, survey archaeologists have begun to think about background disturbance as a major influence on artifact recovery. This term describes the amount of objects in the soil matrix that distract the eye from the ceramic and man-made lithic objects we are supposed to be identifying.  We recorded background disturbance as either light, moderate, or heavy (or none). Our data showed that units with moderate and light background disturbance performed more or less consistently with their visibility. Units with heavy, background disturbance, however, had much higher than average visibilities (70%) and much lower than predicted artifact densities than this visibility alone would predict. This suggests that high background disturbance might influence recovery rates in a substantial way.

Dominant Vegetation Height. For each unit we recorded the dominant vegetation height. This correlated strongly with surface visibility – as one might expect – with densely overgrown units with vegetation head high or higher (!) having average visibility in the teens (18% and 17% respectively), and waist high vegetation averaged a paltry 33% visibility. Interestingly, head high or higher vegetation produced lower artifact densities than suggested by visibility alone, but we’ve long reckoned that our visibility scale runs to imprecise with very low visibility fields. Units with vegetation at knee height coincided produced densities that coincided with expected visibility, but units with ankle height vegetation produced more artifacts than one might expect from visibility alone.

These short studies demonstrate that artifact recovery rates are influenced by a range of variables present in the landscape. Using visibility and artifact density as a baseline for understanding artifact recovery allowed us to recognize the influence of a range of variables that impacted field walker performance. The highest recovery rates appear to come from units with cobble or coarse gravel, ankle high vegetation, plowed, loose soils, and light or moderate background disturbance producing visibilities of between 70% and 90%.

Western Argolid Regional Project T-Shirts

Every real archaeology project needs a t-shirt for every field season. Experienced archaeologists collect these shirts as a living symbols of their archaeological prowess. (And I mean living literally. After a few days or weeks in the field archaeology t-shirts come to support a thriving ecosystem of bacteria, funguses, and tiny insects).

On WARP we invited our students to contribute suggestion for the shirts. All of the contributions were good, but two were the best. 

The front of the shirt shows a field walker in profile holding a compass in his or her left hand. The rakish hat and backpack add a bit of style to the figure. The text says Western Argolid Regional Project 2014.

The back of the shirt, designed by a different student, shows the great Larissa fortress that overlooks the Argive plain. Beneath it roll the six cars transporting the eager field teams through the dawn light to their assigned tasks.

We think they’re pretty nice!

The end is nigh

The end of the season, that is. Tonight was our last regular group dinner at Γραμμές, after which we took a group photo with the Argolic gulf as our backdrop (we’ll post that later). Bill told everyone to pick up a rock, and that led to skipping stones. Even Lena gave it a go. It was a triumph.

The Good, the Bad, and the Ugly on the Western Argolid Regional Project 2014

Yesterday was the last full field day with our field teams on the Western Argolid Regional Survey. So I thought I should do a traditional “Good, Bad, and Ugly” post from our field season.

I should emphasize that the project was pretty remarkable. We covered an amazing amount of territory (almost 5.5 sq km), our field teams held up well, our team leaders remained (more or less) in good spirits, and we produced interesting results. With one week remaining we mostly have odds and ends to sort out, some drawings and photographs, and the usual work of data curation.

So without further ado:

The Good.

  1. Units, Resolution, and Efficiency. We walked close to 2400 units while keeping our average unit size to under 2500 sq. m. and through most of the field season we walked an average of 92 units per day. The average unit took a little over 5 minutes to walk so taken together our field teams walked for around 7 hours and 40 minutes per day or about 2 hours per team per 6 hour field day. There are certainly gains to be made in efficiency, but the cost will be steep with our current manpower.

  2. Good Field Clothing. The project produced a spectacular display of innovative, synthetic, hip looking field clothes. The maquis, heat, spiders, and sweat took a toll on all field clothing. I destroyed a pair of decent field pants, but my Mountain Khakis held up with only one repair (generously made by Sarah James). Better still, my sub-$20 Dickies long-sleeve work shirts proved their reputation for indestructibility. Whatever I lost in terms of being stylish, my clothes survived the rigors of a 6+ week field season.

  1. Beautiful Landscapes. We could not ask for a nicer survey area in terms of scenery. The upper reaches of the Inachos Valley was beautiful especially in the morning light which filtered through the olive trees and the vanishing dew.

P1070124

P1080032

  1. Maps. We mapped our survey units using two sets of very recent satellite images on we printed on a sheet of paper and other we carried with us on our Garmin Oregon GPS units. The two maps were taken at different times of year so they provide different views of the vegetation in our survey area. Mapping onto these high resolution and very recent satellite images was much easier than our practice with earlier surveys where we mapped onto 1:5000 maps or the 1960s era aerial photographs taken by the Greek army.

The Bad.

  1. I’m old. This was the hardest field season that I have ever experienced. My body started to ache about week 4 or 5 and by the end of week 6, I was ill with some kind of fatigue induced cold. My ankle is swollen, my knee is glitchy, and I’m riddled with little cuts, sores, and rashes.

P1080028

  1. Boots. The sharp-edged limestone of the Argolid and Corinthia is absolutely brutal on boots. So far this season, I’ve seen gashed soles, torn leather, eviscerated nylon, and other boot related disasters.

  2. Puppies. I’ve never been a dog person, but I’ll admit that watching the puppy saga unfold this year on WARP was heartrending. I’m glad that we managed to save the “micro-dog” although I’m worried that it’ll never learn to walk properly (although people say at 6 weeks no puppy can walk properly). So this is not a bad thing in a traditional sense, but it was an unexpected emotional outlay.

The Ugly.

  1. Spider Sticks. The Western Argolid is filled with large spiders who build beautiful webs between closely spaced trees. These things are creepy and the webs are sticky and annoying especially when you come upon them unexpectedly while field walking. Students (and staff!) discovered the value of a the spider stick. This is a stick – usually made of olive wood – that can brush aside spider webs as you field walk. Unfortunately, they can also be used as weapons to beat down a team leader who has pushed a bit too hard. We only narrowly averted a spider stick uprising in the waning weeks of the season.

P1080008

  1. Paper Forms. Our data recording involved two steps. Writing on paper forms in the field and keying the data into a database. The days of paper forms are almost over, however. We saw how the Mazi Project is using iPads to streamline data flow from the field to the laptop. I think there is also a chance that iPads will allow for better, more robust datasets that include more images, more field drawings, and more integrated data both in the field and in the lab.

P1080042

3. Larry Potter.  This season was the season of Larry Potter. As my colleagues pointed out, this cohort of students have been involved with Larry Potter from the time they learned to read and the novels, movies, and soundtracks dominate their world. In fact, we had to talk about the possibility that the bamboo sticks used to separate lots in our workspace might be tempting swords, Quidditch sticks, or wands and how that might be facilitate an unhelpful blurring of the line between the productive space of the archaeological workroom and the fantasy space of Larry Potter and friends.

The last day

Today was our last day in the field. We ended our fieldwork on the slopes above and below the acropolis site above the village of Lyrkeia that was, in many ways, the epicenter of our work in 2014. Alyssa and Melanie led a team in a ravine below the acropolis and right next to the modern highway to Tripoli and Kalamata:

IMG_20140710_094414It involved some pretty serious climbing around in terraced (and not-so-terraced) fields with some extreme slopes.

IMG_20140710_100152

IMG_20140710_102325In the meantime, Grace and Phil were leading a team on the slopes just above the acropolis that involved just as much climbing and hiking. I didn’t see anyone fall or falter. It was an impressive display.

As hard as fieldwork is — it leaves us with sweat-stained clothes, our hiking boots broken down from stepping on ancient limestone, our skin scratched by maquis, our noses tickled by wild sage, our knees sore from climbing — it is even harder to leave the field. We work in a beautiful landscape and in it we get to find new things every day. It’s really a lot of fun, so as glad as we all are for the rest, and as much accomplishment as we feel for working hard for six weeks, the last day isn’t really a day of celebration or triumph. It is a bittersweet feeling.

Western Argolid Regional Puppies

Every archaeological project experiences a crisis at some point. Fortunately, the Western Argolid Regional Project managed to avoid all serious crises until the very last week of intensive field work.

P1070980

Over the last week or so a dog and her puppies has been hanging out at the church of Ay. Eleni and Konstantinos in our survey area. Apparently they were left in the care of the saints at some point in the last few weeks. A local woman was feeding the dogs and we provided them with some food and water. On the whole, it was not a very good situation, but one that was stable.

P1070969

One of the puppies grew up and “went off to college,” but the other puppy seemed to be doing fairly well. This weekend, the mother decided that she had done her best and left to try her luck elsewhere leaving the puppy alone.

P1070972

When we understood the situation, Dimitri Nakassis and I immediately panicked. We then called Sarah James. And I then called my wife. All the while Machal Gradoz was bonding with the puppy and decided to take it back to adopt it on the spot. We made a quick run to the vet in Argos and got some puppy supplies and puppy formula and the crisis has been averted.

The puppy’s name is Eleni after the saint who looked after her for the first few weeks of her life.

So for today, we are the Western Argolid Regional Puppy (project).

Photo Friday on the Western Argolid Regional Project

Now, I’m almost entirely sure that there is only one more week of full on field work. This past week was cooler and slightly less exhausting, but we still have two weeks to go before we wrap up the first season of the Western Argolid Regional Project.

This morning, I did some field walking for the first time this year. As we filled in a few units that the survey teams missed, Dimitri Nakassis and Stephanie Steinke check the GPS unit to make sure that we are in the right spot.

The day before I hiked up to the rock shelter fort for the last time this season to fill in a few points on our plans and finish one drawing. It was a cool opportunity to think about how archaeological field work shapes how we hold our bodies.

Bees and Marginal Landscapes in the Western Argolid

Bees! I hate bees. I’m partially convinced by the position of the environmentalist lobby that bees somehow contribute to the good of all humanity. That being said, we should recognize that pollination but like global warming, evolution, and gravity, is a THEORY meaning that it may or may not be true. Consider the lilies of the field, how they grow, and all that.

At the same time, I’ve become interested in the use of marginal landscapes in the Western Argolid for bee keeping, and keep my eye out for evidence of these practices on the Western Argolid Regional Project.

On Monday, we encountered a bee keeping complex on the northern slope of the Inachos valley above the village of Lyrkeia. There was evidence for long term olive cultivation and the neglected remains of broad terraces serve as reminders of grain cultivation.

Today, however, the olives are mostly neglected and the grain has gone wild, but bees continue to be kept and honey harvested. There were a few active hives near the compound (I didn’t get too close!), but it looked like the area was mostly used for the preparation of hives with bee food, broken down hives, and various storage containers in evidence.

P1070608

The compound was filled with empty bee hives, metal lined covers, and the metal racks where the honey comb develops. The wood on many of these abandoned hives is beginning to rot, but the metal frames and hinges will stay behind long after the wood disappears.

P1070610

The Inachos river is another marginal landscape. It is seasonal and during the dry summer months, it serves as a road, dumping ground, and temporary apiary!

P1070707

Further up on the slopes, discarded be hives litter an open field. The frames in some were intact, although the metal lined covers had been largely removed.

P1070720

I suppose in a few years, when all the bees are gone, all we’ll have left to show their impact on these marginal landscapes will be scraps of metal. 

The apotheke

We have an apotheke now. Apotheke (αποθήκη) is Greek for storage facility, but for most archaeologists working in Greece, it means a place where you store and study the artifacts that you collect from the field.

IMG_20140630_141059

Up until today, we were getting the apotheke ready. That meant renting the space, having security measures installed, getting electricity, water, and a phone line installed, and so on. That sounds relatively straightforward, but owing to the fact that we’re not Greeks and that the apotheke had been “off the grid” (no electricity, etc.) for some time now, this took quite a bit of work. It involved two accountants, two lawyers, three iron smiths, two glass specialists, two engineers, two guards, a security company, and three major utility companies (electricity, water, phone).

That also meant that until today we were taking our pottery to the Argos museum. So first thing this morning, we loaded up our friend Andreas’ pick-up truck with 44 crates of pottery and drove it from the museum to the apotheke.

IMG_20140630_083350

These crates were organized by the date that we collected the pottery and tile and handed it over to the museum guards, but that’s obviously not super useful, since each of our survey units is assigned a number, sequentially by team. So in terms of finding specific bags, it’s much easier to organize the material by unit number. That means taking all of the pottery bags out of their crates and reorganizing them:

DSC_0013

It’s kind of a hassle to reorganize 1,527 bags, but with the help of Stephanie’s team (Team 5) we were able to finish the job in a morning:

IMG_20140630_140613

And that left time for Sarah to do some pottery reading in front of an audience composed of Team 5:

DSC_0015

Now that we have the apotheke up and running, we can begin the study of the enormous back-log of pottery that we haven’t had access to while it was being stored for us in the Museum. Sarah and Scott will spend the next couple of weeks reading the pottery and tile as quickly as they can!

Five things

1. A mid-morning blow out

I felt the same way.

On Wednesday Bill and I hiked up the side of the mountain on the southern end of our survey area. We wanted to make sure that we hadn’t missed any major features. The result of our efforts was that we confirmed that we hadn’t missed anything, but in the process we had exhausted ourselves by 9 am and our knees were aching by the afternoon.

2. An iconostasis

IMG_20140624_123039

At the northern end of our survey area, on the asphalt road from Lyrkeia to Douka, are two iconostaseis, one older and stone-built, the other of the regular metal variety. Above is a photo of the interior of the older iconostasis. Note the icon of Αγία Ζώνη (left) and the prophet Elias (rear). Here are the two side-by-side:

IMG_20140624_123117

3. A nice wall

IMG_20140624_112701

Bill blogged about a bridge and mentioned the road that it carried; here is the wall that supported that road. It’s much nicer than the standard terrace wall. In fact, Machal (pictured above) and I came across this wall before we hit the bridge, and I said, “Look at that wall; it’s nice. Could this be a road?” Finding the bridge was a nice confirmation of my instinct. Here’s what the road looks like:

IMG_20140624_112634

4. A pocket terrace

IMG_20140623_080106

Bill blogged about these, too. Now I’ve been obsessively taking pictures of different pocket terraces. This is one of my favorites because the terrace forms an almost-perfect semicircle around the olive tree.

5. Tires
IMG_20140627_085428

Yesterday one of our cars got a flat (an inevitability, considering what we put those cars through on a daily basis) and I decided to get it fixed right away at a local tire shop. They had a remarkable quantity and variety of tires.

… and one last thing:
