Following their mother's death, two Colombian half-sisters visit a cathedral built within an old salt mine.
"She had imagined the church where the funeral was held, but pillared with white salt instead of gold and marble. A sort of whimsical confection. Only upon arriving at the mountain in Zipaquirá does she realize what this sight-seeing really entails: she and Valentina must descend with hundreds of people 600 feet into the earth. It’s a disturbingly morbid activity to undertake so soon after her mother’s death. But it is also something to do, so she buys their tickets and joins Valentina in the long line near a tall cement cross that marks the entrance to the mountain."
