butchers take apart the body, separating soft tissue from bones. The soft tissues are exposed on an elevated rock, just as is. The bones are ground to a meal, then put in the same place. The sky part is that they are all exposed to the sky, and carrion-scavenger birds come from the sky to eat them - and then distribute the droppings about the landscape, to compost and feed the soil community. Excellent! And deeply practical for high plateau dwellers dealing with frozen ground and thin soils over bed-rock. But - alas - too wincey altogether for prissy Westerners.
