We have had snow and very cool temperatures for about ten days now. It's a surprise . We can get snow and cold this early but the temperature usually rises and the snow melts.
So at 7:00 A M Oct. 23, I looked out and saw a Jack rabbit in the intersection. This one didn't have much white on him so he was very obvious.
Now I know there are other years when snow is very late to make it's appearance so there are white Jack rabbits which are obvious. So I would guess that there are very few years where the turning of color corresponds to the snow cover.
I'm sure that many ducks got a nasty surprise when the ponds froze over early this year.
Let me know of some of the things you noticed this year because of the early snow and cold.
