In spring 2011 Swedish extreme skier Andreas Fransson carried out the first ski descent of the immense, inhospitable South Face of Denali.
British alpinist Will Sim was there at the time (along with Jonathan
Griffith they sped up the Cassin ridge in under 15 hours) and Sim
describes the video as follows: " The footage of the south face descent
isn't great... This is the real deal. Raw, cutting edge, and you just
have to "read between the lines" regarding what you don't see. i.e. you
don't mess around with cameras when you're hanging in there for prick of
light at the end of the tunnel." Insightful. Gripping.
