Watch Salt and Rock (1996) : Full Movie Online Free After reading the book "Guide to Hoggar Climbing," guide Pierre Agresti and his wife Isabelle Agresti set off into the Hoggar massif in the Algerian Sahara and tackled the west face of Garet El Djenoun. After a first attempt in 1967, they successfully reached the summit in 1970 and, with an old camera, made a film that remained unused for 25 years. In 1996, they decided to bring the past back to life through the ascent and encounters with the Tuaregs in the rock salt mines of Amadror. The film was shown in competition at the Trento Film Festival in 1997.
