Day 3 (June 28, 2011): A New Way of Life
June 28, 2011
Late yesterday afternoon, Kathryn Ranhorn made her way to our camp. Katie is an American student who’s been doing interesting work in Tanzania for the past year, and will be starting her life as a graduate student at George Washington University, in D.C., in September. For now, she’s come to Olorgesailie to participate in the excavations. And she’ll be helping me out on this season’s blog.
Seventeen of our excavators are helping Alison uncover the finds at BOK-2, and they’ll be hard at work over the next several weeks. I’ll explain more later about how we name sites. For now, let me tell what we’ve found out from our previous excavations at this site – and the reason why we’re going back to dig more.
The sediments at BOK-2 are the younger than the layers containing handaxes. In fact, the stone tools at BOK-2 are of a later technology, called the Middle Stone Age (MSA). BOK-2 sediments date between 493,000 and 220,000 years old, and our team is carrying out tests of the sediments to see if we can obtain a much more precise date in that time span.
Around 12:30pm, the two teams working at Site 15 and BOK-2 were hungry, as it was time to head back to Kampi Safi for lunch – and out of the hot sun for a couple hours. At BOK-2, the crew trekked back to the Land Cruiser only to find yet another small challenge in this rough terrain – a flat tire. Teamwork prevailed, and the tire was replaced with a spare in no time. We had a special lunch, which the camp cooks have dubbed safari njema, which means “nice journey” in Swahili. Let’s hope safari njema will prevent future flat tires!
