ULURU, Australia — The creation stories of the Anangu people are sacred. Some can be shared only with men, some only with women. Some are revealed, layer by layer, as an Anangu grows and matures. Outsiders can be told only what a tjitji, or child, would hear.

Many of those stories reside in the geology of Uluru, the otherworldly red rock in the heart of Australia. For years, the Anangu have asked those who trek to the giant monolith to take them at their word that it is a holy place and should not be climbed. “This is our home,” a sign at the base says. “Please don’t climb.”

On Saturday, that gentle plea will give way to an official ban on ascending Uluru, a national symbol whose auburn folds have graced countless postcards, tourism ads and selfies. It is a spiritual and psychological victory for an Aboriginal people who waged a decades-long campaign, anguished over the physical danger and cultural harm of the climb.
