Cerro Torre - David Lama, Peter Ortner in A Snowball's Chance in Hell

After a controversial first attempt in 2009 and a foiled attempt in 2011, in winter 2012 a rare spell of unbelievably good weather provided Austrian alpinists David Lama and Peter Ortner with the opportunity of making the coveted first free ascent of the famous Compressor route, established by Cesare Maestri up Cerro Torre in Patagonia.

As many will remember, Lama and Ortner achieved their masterpiece just days after American alpinists Jason Kruk and Hayden Kennedy chopped over a hundred bolts off the Maestri route and in many ways this hotly debated act overshadowed the Austrian's success, pushing this extraordinary feat out of the international limelight.

The ascent was documented in A Snowballs's Chance in Hell, a film which follows three years of efforts, trials and tribulations and which has now been made available free of charge. It's worth remembering that the second free ascent of the Southeast Ridge - or Compressor Route - on Cerro Torre was carried out from 4 to 6 February 2016 by Mikey Schaefer, Andrew Rothner and Josh Wharton.
