Aniversario, Hampaturi Range. Aniversario (c. 17,250 feet), the northernmost peak of the Hampaturi range, falls off steeply on the north and east into the Yungas, while the southern and western sides, separated from the other peaks in the range by a gap, are also precipitous. In November 1968 Richard Hartshorne and I attempted a narrow ice couloir on the south side, but were driven back by falling rock. On April 4, Hartshorne, Ted Tucker and I reached the peak from camp on the south by climbing a large couloir to a pass southwest of the peak and a traverse around to the northwest on a snowfield. Here a steep snow finger led to the base of a 5th-class rock pitch, which was followed by easier rock pitches to the summit. This was the first ascent.
