Winter Sampling

As part of my work with Alberta Environment, I often travel to Milk River at Hwy 880 bridge to collect our monthly long term sample.  It seems that almost every time I go to collect a winter sample in snows the night before.  I don't know what the odds of this happening is, but I am starting to take in personally.  On January 19 of this year, on top of the fresh fallen snow, we (Salina Perry and myself) were seeing all  kinds of distortions in the light because of warm air and cold air mixing.  It made the Sweetgrass Hills look like hoodoos instead.
