Ovoos
An ovoo is a triangular pile of rocks, or occasionally wood, usually decorated with blue ribbons, around which you are supposed to walk 3 times in clockwise direction, and then throw on a new rock, or a skull, or an emty vodka bottle, or whatever you like. This is a part of Mongolian Buddhism, but I guess it has a shamanist root.
