On the cover: Crossing the Andes between Chile and Argentina is always an experience, with spectacular scenery, especially on the Argentinean side. In October 2010 Paul Klaassen used the Paso de Jama to cross from San Pedro de Atacama to Susques and drove on to Maimara. The last stretch leads down the Cuesta de Lipan, an excellent paved road, Ruta Nacional 52, that winds itself down the Andes from 4,170 metres (13,680 ft) above sea level at Abra de Potrerillos to 2,192 metre altitude (7,192 ft) at Purmamarca in the Province of Jujuy. There is a spectacularly diverse range of cacti to be found, as various taxa have found a niche habitat at different altitudes. Here the light helps to create a dramatic setting for a stand of Echinopsis (Trichocereus) atacamensis ssp. pasacana.
