After the summer of 2006 we found images on Flickr (taken on August 28th) which showed that all was OK on the ice.
The base station is just visible at the top.
Then we received email from Valentin Burki showing the base had fallen down a deep crack which openned in the glacier.
The view of the side shows the catastrophic break-up of the glacier.
Then we went on a “rescue mission” in November – when the base had been seen floating in the lake! This is what it looked like on recovery.
The rescue trip was recorded for BBC News.
The whole ice front had fallen into the lake – a catastrophic loss of glacier ice.
