Along the way we saw several ovoos/oovoos. An ovoo is a type of shamanistic shire cairn. Ovoos are often found on mountaintops or mountain passes. They serve mainly as religious sites, used in worship of the mountains and the sky as well as in Buddhist or Shamanist ceremonies. Between the stones you can find blue silk scarves, khadags, symbolizing the connection between the sky god Tengger and the earth. When travelling, it is custom to stop and circle around an ovoo three times in clockwise direction to have a safer journey. Usually, rocks are picked up from the ground and added to the pile. Also, one may leave offerings in the form of sweets, money, milk, or vodka.
