In February 1966, Pierre Mazeaud and Lucien Berardini traveled to the Atakor massif, in the Hoggar mountain range of the Sahara in southern Algeria. There, they attempted a challenging first ascent: the Takouba spur, one of the peaks adjacent to Garet El Djenoun, a legendary mountain in the Hoggar massif, first climbed by Roger Frison-Roche and Raymond Coche in 1935. The documentary, superbly filmed by Jacques Ertaud, won the Grand Prize at the Trento International Mountain Film Festival in 1966.
