This made me remember a strange phenomenon I noticed a winter day a few years ago. In a park with some trees there was consistently less snow coverage in a line going away from each tree, always in the same westward direction. Basically following a shadow of the tree. Looking around at other objects I also noticed the phenomenon next to some signs and metal poles.
What could explain this? I could understand if there were more snow or ice in the shadow, as the ground would be colder there, but why would there be less?
- djrogers 5y agoWind. The trees and other structures shielded the downwind area from snow that doesn’t fall straight down.

- sjg007 5y agoIt's probably windy and the snow piles up on the windy side of the tree.
- minitoar 5y agoPossibly less vegetation in shadow of these objects, and therefore less insulation between snow and warmer earth.
- AYBABTME 5y agoProbably prevailing wind conditions.
