SOUTH AMERICA Colombia Sierra N evada de Cocuy, Southern Peaks. I used the upper valley of La Cueva to tackle several peaks in the southern half of this range. On D ecem ber 23, 16-year-old M ateo López, a local hillman, and I, reached a point some 120 feet below the top of N evado G orro Blanco (5047 meters, 16,560 feet), w here we retreated for lack of proper equipm ent to finish the climb. On D ecem ber 26, I m ade the 7th (?) ascent of N evado Pan de A zúcar (5174 meters, 16,975 feet) and on the 31st, the first of N evado del Chifión (5050 meters, 16,568 fee t), to ­ gether w ith A rturo L ópez, also of La Cueva. T he last is a rock-and-ice

peak located on the west ridge of N evado Banco A ncho. I also did my best to collect from the locals m ountain names, to replace the existing nom enclature assigned by visiting expeditions. The following new nam es (or rather, old names, since they have been in use for m ore than 200 years) have been subm itted to the Instituto G eorgráfico A gustín Coddazzi, chief geographical authority in Colom bia; names previously used by climbers are in parentheses: N evado de G ü icán (R itacuba N o rte ), A lto R itacuba (R itacuba B lanco), Pico Los Portones (E l P icacho), Pico Corrales (San Pablín N o rte ), N evado Banco A ncho (San P ablín S u r), Pan de A zúcar (C oncavito), Pico Los Portales (Pico D aniel T ru m p y ), Pico P úlpito (Pico Toti G an sser), C am panario (C am panilla G ra n d e), N evado del P úlpito (Pan de A zúcar) and C am ­ panula (C am panilla C hica).
