Snow that Survives

There is plenty of snow on this tree stump, but very little nearby, why?

The stump means that the tree that was once there has now gone – the sky is open, so the snow can reach the ground there easily. But that is also true of the ground next to it.

The stump lifts the snow off the ground. The ground is warmer than the air a foot above it.

The stump’s wood is also a good insulator and stops the heat from reaching the snow and keeps it cold.
