Has anyone come across a hard white layer while digging? It is about a half inch thick..almost like cement but breaks easily? About a foot down..if so, what is it?
Based on the limited description, I also would say it is lime. This substance hardens to an almost rock hard texture, and was either sprinkled in the privy and is a thin layer, or the entire bag was dropped in and is still in that form. Lime usually requires quite a bit of chipping to break it up and remove. It also often means the bottom is near as it seems to sink over time. It could also signify the beginning of an older layer...or you are digging up a body
