'Ludi ar aris ts'udi' is the transliteration of this post's title. As you can see, this fitting phrase for a refreshing beverage on a hot day also has a nice ring to it. It also was one of the many new actual sentences I have been taught over the course of the last week at Dmanisi. Also, helpful phrases like 'where are you going?' and 'Go!' have now been added to my Georgian vocabulary. I really wish I could speak it and understand more of it because I would really like to ask questions to the people in the village that are also on the excavations. None of them speak English, or are limited to 'Thank you' and 'Hello,' which isn't too much different than my level of Georgian. It would also be nice to hear what the others are talking about in the camp. It is amazing how much fun they have at the camp and how much they smile and laugh at all hours of the day. Although I don't understand most of what their saying (I say most because once in a while someone will translate for me), I can't help but smile and laugh along. Which may be ironic because my current facial hair situation may be the butt of their jokes. Ha. But I digress...
The last week has been pretty fun but exhausting. We arrived in Dmanisi last Saturday to some newly uncovered bones in M5, which I got to partially dig out at the end of the day, since Reid had to pay the workers and there was no one else there. It turns out that that square produced about a dozen bones, including a bear mandible and a rhino humerus. Pretty cool stuff. There are also two pelvis halves in the ground that should come out this week. Getting there Saturday also meant overlapping time with one of the field school students from last year. He was leaving on Monday so Saturday night we drank up the Chacha that Sergio gave me and about a third of a bottle of vodka. Not too much, but enough for bakhmelia the next morning. (You can figure that one out I'm sure. :) )
We had only planned to stay until Monday, but as I was getting prepared to catch the Marshutka (small bus) back to Tbilisi, we decided that it would be better for me to stay behind while Martha and Julia went back. I was happy with this since it was nice and cool in Dmanisi and I would get to excavate. I was hoping to work in the square with the bones, but since I am not so experienced with taking fragile bones out of the ground, I was assigned to a different square. I was fine with that and started to go to town with the rock hammer. At Dmanisi, the sediment is so hard that a rock hammer is really the only way to get through it. Some layers are basically cemented together and they are taken out by Hilti, our resident jackhammer. I usually have no trouble moving dirt, as I have had a lot of practice in my teenage years (Thanks Dad!) so I was going back in time at a pretty good rate. After about 30 centimeters down into my square, and about 3 or 4 meters below the actual ground surface, I reached the line that separates the two different types of sediment. The line is indicative of a magnetic reversal on Earth, which has happened dozens of times over the last couple million years. This reversal means that the magnetic north of the planet had actually switched from the north pole to the south pole, and these reversals have very reliable dates based on a dating technique called Paleo-magnetism. This concept is way over my head to explain any further so I hope you got the gist of it. Anyways, this line basically means that I had reached 1.78 million year old sediment. These sediments from this line and downward to the basalt, which is 1.85 million years old, were all ash layers from volcanic eruptions and are the reason that a lot of the bone preserved so well, because they were buried right after they were deposited.
So, before I had reached this line, I found a pebble or two. Nothing very exciting for a day and a half of swinging a rock hammer into the dirt. After the line, my luck didn't get much better. I found one unidentifiable bone fragment that crumbled if touched and a few cobbles, or larger stones. Finally on Thursday I found an artifact, which was a nice piece of stone that had flakes taken out of it, which could be from early humans flint knapping, or making stone tools. On Friday, I reached a lower sediment and found 6 artifacts in the same 10 centimeter layer. Pretty exciting stuff. Of course after things start heating up, the day ends and I was summoned back to Tbilisi.
I knew that my time excavating wouldn't last very long, but it was fun while it lasted, and the physical toll it took on me did not go unnoticed. Maybe that's why people weren't going as fast as I was, but I'm leaning more towards the fact that I didn't find much. On Saturday we washed artifacts and I had a break where I went to the site and met Martha and Dr. Bernard Wood, who is a professor of Anthropology at George Washington University in DC and one of the big names in Paleoanthropology... and my roommate for the next few days. Ha. Martha gave a tour to a bunch of people from the US embassy who knew very little about the site and even less about archaeology and they were apparently pressed for time because the tour took about half the time it was supposed to.
Sunday was when the field school students arrived, which consists of 10 Americans, all girls, and 3 Georgians, two boys and one girl. Adam, the field school instructor and a professor at Wellesly in Boston, and Zach, the field school assistant, also arrived then and it was nice to see both of them again this year. We ate dinner with them at the camp and then took the museum bus back to Tbilisi, with Zaza driving, who has been driving for the museum for a long time, and we arrived in about half the time it normally takes that trip. ha. It was really bumpy. That's all I have to say about that.
I was summoned back to Tbilisi to look at more bones in the Museum, which are all fragments of limb bones. We are taking measurements of the angles of the breaks and are going to compare them with the previous measurements we took on the elk bones that I broke last fall and compare them also with other papers. We are planning on writing a paper on bone breakage this fall and submitting it to a journal of some sort. This paper will be a chance for us to publish our experimental data, some of our field data, and some of our problems with methodology and inconsistencies in the previous studies. It should be a fun paper to work on and a meaningful first publication. We spent most of the day measuring bones today and will tomorrow as well, until we have to go to Dmanisi for Dr. Wood's lecture, and then come back tomorrow night.
It's pretty hot in Tbilisi and I miss the scenery at Dmanisi already.
Another long winded entry but I hope you enjoyed it.
I will write again sometime soon.
