Even with the prevalence of digital capture, it is only every once in a while that we see something entirely unprecedented.

Growing up in the mountains, I always felt like geologic change was real, but not the kind of thing that happened in human time. I was in awe of how glaciers grew and receded, carving the mountains into the seductive shapes that inspires us to learn to ski and climb; but I always believed that I wouldn’t live long enough to really see the changes.

How wrong I was! Just a decade of working with CMH Heli-Skiing has been enough to see dramatic changes in the glaciers of the Canadian Rockies. During the same time, geologic change seems to be accelerating in many parts of the world, and with the phenomenon reaching beyond the niche circles of skiers and mountaineers, people are aiming cameras and instruments at our planet in new ways.

Perhaps the most dramatic example of this change being captured “on film” is the Chasing Ice project. By using time-lapse methods the team, led by photographer James Balog, set out to capture geologic change in a human time frame.

The results, starting with a National Geographic Magazine assignment in 2005, have received global attention. The project has continued, and with cameras trained on galciers all over the globe, perhaps it is not suprising that something extraordinary would be revealed. Recently, a team of photographers in Greenland captured something that defies all our previous assumptions about geologic change.

While shooting a tongue of glacier that has receded as much in the past ten years as in the previous 100, they stumbled into filming the largest glacier calving that has ever been captured on film. This is not a time-lapse, but instead a city-sized section of glacier falling into the sea in little over an hour:

This video clip is perhaps the most stunning thing I’ve ever seen on film. It is part of the film “Chasing Ice” which is showing in North America and the UK during 2013.

Thankfully, here at CMH Heli-Skiing, we still have a vast wonderland of safe and skiable glaciers positioned right next to epic tree skiing; but I gotta wonder; will my grandkids be able to ski these glaciers too?
