Excavation in 2019 seems to confirm our tentative, preliminary interpretation from 2018. This layer most likely represents some kind of leveling layer, after the abandonment of what may have been an earlier surface (roadway?) that occupied the space of this corridor. The presence of such a density of large basalt stones makes it almost certain that it is an intentional deposition, but it doesn't appear suitable to be a preparation layer for another road surface, and thus the roadway (or alley/corridor) has probably gone out of use as such when this layer is deposited.

Without excavation in 2018 season, secure interpretation is impossible. But, together with its equivalent layer 7242 in Room 5 (to which it seems to connect below wall 7114/7115/7185), this compact spread of basalt stones seems to represent an important horizon or discontinuity in the occupation of the original corridor delimited by ashlar walls 7108 (east) and 7038/7078 (west). It may be a kind of surface (for a 'roadway' or passageway), or just a large leveling layer before the construction phase that divides what had been a long corridor into rooms for the first time (by the insertion of wall 7114/7115/7185).
