Clark (1987) documents a substantial collapse horizon in the Post Stratum III gap that he interprets as either the result of earthquake damage or long-term structural decay. In H.1, he records that “a 0.25 m deposit of rock tumble and windblown loess (H.1:010 and 011) overlay the Early Byzantine I–II occupational deposits,” noting that this deposit “appears to represent a period of abandonment and of building collapse.”
