Anchor Ice Dam on the Kananaskis River

???????????????????????????????

Anchor Ice Dam on the Kananaskis River, AB (Canada), Nov. 28, 2012

Anchor ice occurs frequently on the Kananaskis River – it forms when suspended frazil ice adheres to the stream bed.  In some cases the buildup of ice on the bed can get large enough to create a little ice dam or weir, and the water backs up and spills over in dramatic fashion. MSc students Stefan and Vincent found this ice dam on the Kananaskis River in November 2012.
