       The cycle of the seasons turns once again.
By late fall the ponds freeze enough to support
the weight of small mammals and with the first
dusting of snow their secret night time activities
are revealed as if by magic as they use the flat,
even surface of the pond to travel about their

       There are many stories printed in a thin skim
of early snow that allow us not only to identify the
wild animals involved, but also to put the still
image of the animal in motion in the mind's eye
and watch it interact with its habitat.
Come along this early winter and try your hand at
identifying and interpreting the trails in the snow.
