Pisco Oeste, South Face, and Chopicalqui, Southwest Face. A number of new routes have been done on the south face of Pisco in the past few years. It is not altogether clear just where these routes have been made. Maurice Barrard made a route he believes is new in an hour-and-a-half on July 26, 1977. That same day Christian Bougnaud and Liliane and Alain Bontemps repeated the same route, which followed a central couloir. On July 29 and 30, 1977 Barrard, Bougnaud and Patrick Vallençant did a different and direct route on the same face. On July 21 and 22, 1977 Barrard and Vallençant made what they called the first ascent of the southwest face of Chopicalqui. Since the southwest ridge is the standard route on the mountain, it is not known if their route went left or right of the ridge. On June 5, 1978 Marie-José and Patrick Vallençant and Dominique André descended the normal route on skis. At the end of July V. Lant soloed in two days the north-northeast face of Chopicalqui.
