Glaciers grind and churn with slow but brutal force, and any bodies within them are generally crushed to molecules. Very occasionally they are stretched to outlandish lengths, like characters flattened by a steamroller in a cartoon. If no oxygen gets to the body, it may undergo a process called saponification, in which the flesh transmutes into a waxy, foul-smelling substance called adipocere. Such bodies look eerily as if they have been carved from soap and lose nearly all meaningful definition.
