As the sun warmed the roof, ice fell from the eaves. (I know, more insulation.)

We tend to think of permaculture zones as concentric circles on a plane of two dimensions. Here, however, is a vertical zone: The zone from the eaves to the ground onto which ice chunks fall — possibly smashing a milk jug! We need to think in at least three dimensions.

So, in this case, the nano-climate under the eaves includes ice chunks falling from above!
