About ten years ago I was doing labour work for a small backhoe firm and we occasionally dug a few graves, this was during the winter too. Most of the time it was pretty uneventful I cleaned up around the grave site and helped setup the green carpets they used around it, shoveled snow if it was tight, etc. Well the boss who was running the backhoe was taking his last few bucketfuls of dirt out when one wall of the hole caved in exposing the side of a pine box and then all the water that was in that grave started pouring in. I was probably 19 at the time and been around a few sewer and water excavations that sloughed in growing up as a kid but not a grave I thought I was going to see who was next door. lol Well I cant remember exactly how the boss cleaned it up but I seem to remember he bucketed out most of the water and hid it in the snow I think, then he used some of the dry mud he had already dug out and mixed it with the slop and cleaned it up pretty nicely. He phoned the funeral director people and they brought some longer carpets to hide the other box and nobody found out about what had happened. We backfilled normally and while I was still freaked out about it, the boss told me that was nothing he had hit unmarked graves before. Sorry if I went off topic I just wanted to tell my little bit of excitement with grave digging.
