This may sound like a question for my local cemetery association rather than TOH, but here goes. In December of 2004, I lost my best friend of 14 years, Heidi (my Labrador Retriever). My yard contains more slate rock than soil, and is extremely difficult to dig, especially being partially frozen. It was pouring down rain when my champion of a brother managed to dig her a grave for me, shallow as it was (about two feet deep). (She was too large to keep in the deep freeze until Spring thaw.) The vet had placed her body in a thick plastic body bag for transporting her home in my car, and unfortunately, I did not remove her body from the bag when we buried her. I did, however, tear the bag open on top thinking it would help with the decomposition process. Well, there is still a pretty good sized mound where Heidi is buried. I have tried planting flowers in that area and I place my birdbath on top of the mound as a "marker" of sorts. Will this "grave" ever settle properly with that bag in there among all the slate rock? I don't want to grade the mound down and maybe find her bones. The only thing I can think of is to use one of those heavy concrete yard roller things to try to "push" it down, but the thought of doing that feels awful. Suggestions?
