Georgian Bay in Ontario, Canada, is part of Lake Huron. Parts of the lake close to the shore freeze every winter. But in late February, as the sunshine gets longer and the temperature gets warmer, when the northwest winds are strong, the ice gradually breaks up and melts, forming floes of different sizes, which, driven by the wind, pile up on the shore, creating walls of ice up to two or three meters high. Although it is still a picture of winter, but it is not far from the spring. Right now，the sun is shining on the ice, it gradually melted and opened a big hole that seems to swallow the sun.
