Virtually every snowflake that falls on Fortress Mountain in the Kananaskis region is recorded and watched. "We're in a time when we get extreme weather and a changing climate," said John Pomeroy, director of the University of Saskatchewan's Centre for Hydrology.  "We try to follow every drop of water, every flake of snow, and see where it's going." The Centre for Hydrology's Coldwater laboratory is made up of stations with instruments placed on the ridges, glaciers, valleys, and creeks in the Alberta Rockies.
