The Snow Line?

Not as you might, normally, expect as a result of altitude; but I suspect we actually saw a tiny touch of Sun.  The Snow line ocurrs at about where the, currently quite low, Sun would fall across the lawn.
It's, almost, a cue for a song?

Seems "The frozen North" is getting off light again?
