From the La Paz basin, the road climbs over 1,000 metres to the La Cumbre pass (picture) at an altitude of 4,643 metres, before descending into the Yungas via countless hairpin bends through a deeply incised U-shaped valley, with the Cordillera Real towering in the background. The treeless scrub and grassy vegetation of the Puna still covers the saddle here, where indigenous people are resting with a herd of llamas. A little further down the valley, scrub begins to appear, until finally a dense forest takes over. - Book: Picture 2 - Bolivia - 1976
