After the summer of 2006 we found images on Flickr (taken on August 28th) which showed that all was OK on the ice.

Then we received email from Valentin Burki showing the base had fallen down a deep crack which openned in 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.
