Field dispatch: update from Olduvai Gorge

University of Colorado-Denver fieldschool student Tracy Lancaster preparing to piece-plot materials in Unit L10.
I'm sitting here at the Sundown Restaurant in Karatu with my first real internet connection in about two weeks. The work at the gorge has been going very well; our excavations at DK have now exposed nearly four square meters of deposit, and faunal material is very common. Importantly, most of it appears to be very well preserved. Unfortunately, we have not come across any definitive stone tools as of yet, although a few pieces that were excavated yesterday may have been produced by hominins. I'll provide a more detailed summary of this year's field season next week when I get another stable internet connection...

View of our excavation trench in the DK area. The thick deposit at the top of the sequence is Tuff IB, which is dated to approximately 1.85 million years ago.
