|Building F9 was an unusual
building in many ways including its squared-off shape with rounded corners,
regularly spaced interior posts that may have supported benches, and the
mass of debris, including broken ritual items, found on its floor. It looks
like the building was "ritually trashed" after it was dismantled
and burned. (Also visible is Building F29, an earlier structure built and
dismantled before Building F9 existed.) Graphic by Dee Ann Story.
