Wind and water eroded a hole in the ceiling of this Monument
Valley cave. The formation is known as "Big Hogan" since the cave resembles the traditional
Navajo hogan. These round dwellings include an opening in the ceiling so that a fire may be
burned inside. The use of a hogan is dictated by its construction - the "female hogan" being
the family dwelling, and the "male hogan" being used for sacred ceremony.
