The call of the hoggar, in the heart of atlantis (1935)

Documentary on the French Alpine expedition to Hoggar in Algeria, starring Roger Frison-Roche, Raymond Coche, Pierre Lewden, and François de Chasseloup-Laubat. The 1935 French Alpine Expedition to Hoggar was conceived and prepared by Lieutenant Raymond Coche, the ideal leader for an expedition that would combine alpine and Saharan terrain in Algeria. Among his goals, he set himself the task of leading a French rope team to the still-untouched summits of Atakor and Tefedest and planting the French flag there. His old friend, Pierre Lewden, an athlete and journalist, was soon on the team, and to complete their project and complete the trio, they called on Roger Frison-Roche, a guide from Chamonix and one of the best climbers of this generation. A few days before their departure from Paris, filmmaker Pierre Ichac joined them.
