Calving / by Strain

Some photographers will sit and wait for days at the terminus of an ice sheet, hoping to capture on film the awesome power of hundreds of tonnes of ice peeling away from the glacier and thundering to the ground below. I don't exactly have that kind of time while I'm at work, so I kinda figured I'd never manage to get a photo of calving in progress. Unfortunately, my camera was secured in its pelican case for the main event: about an hour after this, a block the size of several houses broke loose, shaking the ground as it crashed several hundred metres to the valley floor...
