Two of our field crews adjourned to the far western part of the field to continue exploring this new part of the site, while the other four crews continued work on the wall-trench structure.

About 10:00 in the morning, we had a fly-over from one of the most awesome birds ever built - a B-17 Flying Fortress.

Thanks to a new telephoto lens I bought over the weekend, I managed to capture this plane up close and personal...

While cross-sectioning one of the wall trenches, we documented the post holes in profile -- these holes tell us the diameter of the posts that were used in constructing these buildings and a great deal about the "above ground architecture" that no longer survives.

We continue to open new excavation units exposing the walls of this ancient building.

As the day proceeded, we found what we think are the eastern walls of the building -- and what appears to be a second wall-trench building to the south with an interior pit and hearth.

By about 3:00 pm, the sky was warning of impending rain...

So we shut down our excavations quickly and made it out of the field before the thundershower hit.

We are making great progress on finding the pieces and parts of the ancient town that once dominated the landscape of Sumner County around A.D. 1200. Over the next three weeks, we will focus on trying to understand how these pieces and parts fit together.

Tomorrow, we hope will be a wash for our field excavations -- our friends in the Castalian Springs neighborhood desperately need some rain to salvage their crops. We'll probably work in the lab most of the day washing artifacts.
