Watch out -- there's a glacier stalking you

As part of my occasional series extolling the virtues of glaciers and the work of ice, I came across these pics. Wow! This is Fridtjofbreen in Svarlbard. The photos were taken in 1996, around the peak of a surge that caused the glacier to advance 2.8 km between 1991 and 1997. At the peak of the surge, the glacier ice was moving at 4.2m per day, or almost 30m per week or about 130m per month. The lower photo shows that the ice was moving so fast that the glacier surface was literally torn to shreds.....http://www.unis.no/35_STAFF/staff_webpages/geology/monica_sund/web/New/glacier_surge_sund_unis.htm
