On March 9, Eduardo Baca, Yjeguel Camasa, and I climbed Nevado Bonanta (ca 5,300m a.k.a. Bonomia), a large, rounded glacial summit on the ridge extending west from Nevado Veronica (5,893m). Our route up the east ramp had a short, easy, but very exposed 5th-class rock section to gain the glacier. Here, I found an old Charlet Moser ice axe; I believe it is from the 1958 Italian expedition that made the first ascents of Bonanta, Huakeihuilqui, Marconi, and the Chicon peaks farther east (AAJ 1959). 

The climb onto the summit plateau was straightforward on 120m of 50° ice, after which we post-holed up knee-deep snow until the summit (300m, PD+). There were no views, as it was still the wet season, but they would be spectacular on a clear day.
