Sunrise over the Hoggar Mountains. At 5.30 am, the crew planted their cameras right outside the small stone chapel on top of the plateau, waiting for the sun to rise while being pounded by a freezing wind. I moved away from the peak, searching in vain for a sheltered camera position. Dawn broke and the sun burned through the frozen mist. Suddenly, the peaks of the Hoggars, some of the highest in the Sahara, seemed weightless, and I recalled the words of José Martí: ‘Should you see a hill of foam / It is my poetry you see / My poems are mountains / And feather fans.’
