1992 TOP SECRET CODE
PAGE
The main code that we used
in 1992 involved site gridding.
Site gridding is done each
time you excavate a site because it keeps
everything organized.
You may have seen excavations (or 'digs') where
the area looks like it is
separated into little boxes by string and pieces
of wood. Well, this
is site gridding.
