It is that time of year when nature likes to get out her frost compasses for us to admire.
I took this photo last Friday in the middle of the day.
We are looking due west.
The southern sun has thawed the areas it can get to, but unlike other suns, it cannot refresh the parts it cannot reach. (My apologies, I think a retro marketing slogan tried to creep in there.)
The frost shadow on the sand itself is quite straightforward, but the shadows and frost on the logs are more interesting, particularly when…
It is that time of year again. The sun and Jack Frost are working together to paint the land.
In this photo of a dog-mauled football, we are looking southeast. But why does the football's shadow appear longer than the patch of frost? Surely, since the sun is rising it should be the other way round?
Useless clue: it doesn't have anything to do with the dog, who wisely avoids footballs until they are well defrosted.
UPDATE: The patterns of frost we see as the day wears on are shaped by more than one factor.
