Pressure cracks appear when ice contracts when the temperature falls and expands and forms ridges when its temperature rises. Fluctuations in recent temperatures led to the cracks, and the lack of snow made them visible. The cracks usually originate from a weak spot on the ice cover. After days of freezing temperatures and fluctuating thaw, pressure cracks may appear in the surface of ponds, puddles and lake ice. Loweswater, Cumbria.
