Oversand is one of the first films about free climbing, the third film in a series of three with "Overdon" and "Over-Ice". Directed by Jean-Paul Janssen, the film was shot in 35mm in Algeria, in the Sahara Desert, in the Tamanrasset region, on the walls of the majestic peaks of the Atakor massif, central sub-region of Hoggar, mountainous heart of Hoggar, a volcanic plateau of almost circular shape, whose average altitude is 2000 meters, and which culminates at Mount Tahat (2918m), the highest point in Algeria. The Atakor is distinguished by its spectacular volcanic peaks, its needles, and its rugged landscapes, resulting from the erosion of ancient volcanic chimneys, which make it the most emblematic summits of the Hoggar, such as the Assekrem, the Ilamane, or the Tizouyag, where climbers Patrick Edlinger, Patrick Bérhault, Bernard Gorgeon, Hugues Jaillet, Jacques Perrier, Stéphane Troussier and Odette Schoënleb evolve under the watchful eye of the Tuareg caravans.
