The milkbottles on our doorstep had frozen. Gold Top milk expands more than silver top when frozen, and silver top melts faster, so that the silver top had made a little puddle of cream around itself, whereas the gold top had just thrust its contents skywards and left it at that.
Yesterday I walked near Tavistock with my sister and my mother and her dogs, under a fabulous red-skies sunset, with the folly on Kit Hill silhouetted against it in the distance. This morning, I saw a puddle in a hollow on the hill which had frozen fast and created a huge spiral swirling pattern of air trapped under the ice. Of course, I didn't bring my camera either time...
EDIT - on my second walk of the day, I noticed that the snowdrops which were all in bloom have frozen solid - some of them had melted in the sun, drooped and contorted, then re-frozen in strange sad twisted shapes. There's something strangely violent about such a sudden cold coming on a landscape that was warming and unfolding ready for the spring : it's not like the expected process of going slowly to sleep for the winter : it's more painful and ugly.
EDIT2: Saturday - And now it IS snowing! Though only an inch or so and it's not so cold.
