Winter Shadows

We thought this photo-collage would be instructive and demonstrate the power of the sun. The border between the snow and the lawn moss shows where the sun shines when it passes through the local meridian.

In about a month, around the Spring Equinox, the snow shadow would bisect the block circle around the cherry tree.

If the snow had fallen on the Winter Solstice, there would be no green in this collage.... well, maybe some from the sunlight reflecting off of our house.

By the time Summer Solstice rolls around, the sun will shine on the entire yard, except where the back fence casts its shadow.
