Urus Este, south ridge; Huamashraju, west face; Pisco, Miss You Baby; various ascents
Peru, Cordillera Blanca
In June 2012, Michael Wejchert and Erik Eisle (U.S.) made an ascent of the rocky south ridge of Urus Este (5,420m), believing the line to be unclimbed. [This expedition was backed by an AAC Mountaineering Fellowship.] Previously unrecorded, the route was climbed by Smith Curry and Jason Foote (U.S.) in 2004, and it’s possible it may have been climbed prior (70° M4).
On July 18, Katty Guzmán and Maria Ramírez (Colombia), along with Jared Vagy and Cory Harelson (U.S.), climbed a possible new route on the west face of Huamashraju (5,434m) in the vicinity of the Sims-Jackson route [AAJ 2005]. Six pitches of rock climbing (up to 5.8) led to a snowfield and the summit.
Additionally, in August 2012, Darfur Hefti and Gian Marco climbed a possible first ascent, Miss You Baby (300m, 6c+), on a rocky spur on Pisco (5,752m), starting from the Paron Valley. Further information is lacking about this climb.
