glaciers continuously creep to lower , warmer elevations – it is because of thermodynamics ( raising pressure from later snowpack causes a change of state from solid toward liquid ) and gravity causing the mass to slide down the slope . It is not surprising that the AGW crowd try to use the story as ‘proof’ of warming .
Very interesting story about the finding of the bodies and equipment , preserved for over a century . Sounds like they were executed rather than taken as prisoners .
