A question out of the blue.

[LeeKen]

I was walking today and notice blue tinted snow. It looked like windshield fluid had dripped on the snow. Twenty feet later more blue, it appeared at least six times that I noticed. All spots were areas that multiple deer had passed through and there was also deer droppings and urine stains. There was no signs of recent human activity. Anyone ever see this before? Any explanation?

Deer eating juniper (red cedar) cones (look like berries) would be my guess. I usually start seeing those blue spots about this time of year

Blueberry Artic Blast?

Tamrack,cedar,juniper all get eaten by deer and come out blueish.Look at bunny trails you'll see the same.Its when we can see their excretments (in the snow) and the time of year that they eat those heavier than early winter.

Good chance it is from them eating buckthorn berries

Deer eating buckthorn berries. You will notice the blue spots are usually very near to the buckthorn.

Not only are the berries very dark, they are a natural diuretic.

Smurfs would be my guess.
