SU 6195 is a layer of concrete that runs underneath and binds together SUs 6193, 6194, and 6284. It also covers partly the road curb SU 7020. SU 6194 is a north-south wall dividing rooms G-1 and G-20. We believe based on twin semi circular features [one at the western end of G-20 (SU 5866 and SU 6095) and the other at the eastern end of room G-1 (SU 6051 and 6032)] that rooms G-1 and G-20 were previously one continuous space. At some later point in time, wall SU 6194 was constructed, separating the space into two rooms. Because SU 6194 sits on the same concrete (SU 6195) as the pier base SU 6193, perhaps the row of piers that line the southern portion of room G-1 date to the time when this space was divided, rather than running the full extent of both rooms G-1 and G-20.
