Photos by Camilo Lopez - On November 27th, 2009, Anna Pfaff and Camilo Lopez successfully completed a traverse of all the peaks in the Laguna Grande de la Sierra Located in the Sierra Nevada del Cocuy, Colombia, South America. The Laguna Grande de la Sierra is located on the West side of the Sierra Nevada del Cocuy. It consists of six peaks: Pre-Concavo (5,100 m), Concavo (5,215 m), Concovito (5,115 m), Portales (4,920 m), El Toti (5,125 m), and Pan de Azucar (5,235 m). We climbed in five days, alpine-style using four high camps along the traverse and having no prior acclimatization.
