Hi everybody who might be interested - I've just posted a trip report from my summer's trip to the Cordillera Blanca with lots of pictures and descriptions of our climbs up Vallunaraju, Tocllaraju, Pisco, Chopicalqui, and up to col camp on Alpamayo. If you're interested, please check it out and let me know if you have any suggestions or comments!
