Twisting twin canyons

This probably isn't your first time seeing Antelope Canyon—this red-sandstone marvel is the most photographed slot canyon in the United States. But did you know it's not just one canyon, but two? While in English we refer to the whole site as Antelope Canyon, the local Navajo language gives it two different names: Tse'bighanilini ('where water runs through rocks') for the well-traveled upper canyon and Hasdestwazi ('spiral rock arches') for the less accessible lower one. In line with the canyons' temple-like atmosphere, they're considered sacred spaces by observant Navajo, who bless them every four years in a special ceremony.
