Last night temperature was below zero, but not too cold. To my big surprise it was cold enough to let the small duck pond in Skelleftehamn freeze over completely anyway. The yellow-brownish leaves lay on, in and under the thin new ice. The rudtjärnen – a lake perhaps twenty times as big – was completely open by contrast. I had a look at the rocky landscape nearby and most of the puddles were frozen over with 3mm ice, too, but not all of them. I guess, there must be some warmer spots in some places even if the sun is hardly shining.
