We resumed excavating the trench, finding several slumping layers of soil but no wall. One of these soil layers contained a large amount of small mammal bone. Unfortunately, we failed to find any artifacts within the small builder’s trench in TU 3 that could help us date the stone wall. We also documented evidence of extensive rodent activity that has mixed soil layers even at the base of the foundation wall. To explore the wall further, we opened TU 5 on the other side of the stone wall. We hope this unit will explain the nature and sequence of the structures.
