This structure of tufo blocks appears to relate most closely to the drainage feature of Rooms 4 and 5 (7196/7201), which may terminate here. Based on their orientation, the interface with wall 7108, the use of mortar, and the reworking, it is clear that these blocks have been repurposed, and do not relate to the original phase of the Area H complex. Further investigation is necessary in future seasons in order to more fully understand this feature.
