“We know it didn’t really happen like that, scientifically speaking, but that doesn’t make the river any less important to us,” says Hayri Dede, a respected leader of the Alevi religion – a mystical faith with strong shamanistic and Zoroastrian roots, a complicated relationship to Islam, and an intimate and sacred connection to the natural world.

Alevis emphasize inner spirituality over outward displays of devotion; tolerance for people of all races and religions is preached and practiced; and music and dance are essential features of their ceremonies. With holy sites scattered all around Munzur, the valley is the spiritual heartland of the Alevi people, says Hayri Dede. And he desperately hopes it remains so.

“If the dams are built,” he says ruefully, “it will all be under water.”
