We keep a constant flow in our gravity feed water system all winter long so that it doesn’t freeze up. The flow drains into my pond and where it enters the flow keeps a small area on the pond’s surface from freezing. I suspect the ice on the rest of the pond is at least 8 inches thick. Around the unfrozen area, frost has formed during our -24°C (-11°F) cold snap.
Surprisingly, two different distinct types of frost formed; one very feathery and fluffy looking while the other, more like white blades of grass. I guess something was subtly different in the two areas.
