Typically, traditional Jewish burial law calls for a speedy burial in the ground, with no embalming or other unnatural preservation of the body. But what about if the ground is too frozen? Nowadays, cemeteries have technology that allows them to dig through frozen ground, or thaw it with heat lamps. But this technology is relatively new. I'm curious if anyone knows of Jewish burial law that relates to preserving/keeping bodies until the body is able to be buried.
