With lots of great photos.
At the end of 2010 we thought that we might have found the point at which the mud brick running north-south along the full length of the west side of the excavation area made a corner with the east-wall at the south end of the excavation. As is evident in this photo taken then, the brick was very friable, its excavation requiring more time than we had left. Clearing up this question is one of this season’s goals.
We extended the excavation further to the south and by mid-morning on Thursday (our 2nd actual day of digging) knew that last year’s theory was wrong: not only does the long wall keep on going, but it gets wider. The meter stick is on the newly-found brick of the long wall, and the north arrow sits on another wall that meets the long wall’s west face. We do have a corner, but it is an inner corner where the east face of the long wall meets the south face of the large east-west wall mentioned above.
