The Flathead Indians, who's reservation is now in Montana, once practiced a regular and actual "flattening" of their tribe member's heads. This would be accomplished using two boards strapped together around an infant's head before the cranium had developed its complete rigidity. As the cranium hardened over the weeks, it would take the flat shape of the board. The flat spot created would extend from just above the eyebrows to a peak in the middle-back of the top of the skull.
