Seriously, what is with the dead people?

I either have the best or the worst luck. It seems like no matter where we put an excavation unit, or for what purpose, we keep ending up with skeletons! We’re trying to dig a pit through to sterile (non-cultural) soil to document the time periods of the site. All I want is pottery to match up to some other sites. So of course we find another burial. The very edge of it skims the unit that we’re working in, but of course it’s the edge that contains an entire (though fractured) vessel, which is now sticking out of the wall. Previous experience has told me that things like that left in the wall of an excavation unit won’t stay there for long, so we’re having to open an adjacent unit to do this thing right and get that person out of there.
