[Flashpoint]

I took an archaeology course where we went to the Calgary coroner's office and had a slide show showing the various stages of decomposition of the human body. Things like a homeless person who fell into the bow and died, and what he looked like when they pulled him out next spring. Or what was left after someone burned to death. The point was to show what parts of humans survive in the archaeological record, and ways to potentially determine cause of death.

We ran out of time before we got to the "mass casualties" event.

I actually found it to be absolutely fascinating material. Grisly though it was.
