Sub-Zero explores the souls of four top Canadian ice climbers and this time we meet John Freeman, a mountain guide and rope access supervisor living in Canmore, Alberta, Canada who was recently in the climbing news for establishing a new route at Helmcken Falls with Will Gadd called 'Overhead Hazard'. John also happens to have survived one of the craziest ice climbing falls ever recorded when a pillar of ice he was climbing detached from the cliff face. This exclusive footage has waited for over two years to see daylight and we're delighted to share it with you. Ice Pillar Snaps with Climber on It, Here's How He Survived | Sub-Zero, Ep. 3
