This is my contribution to the Cosmic Photo Challenge: Forces of Nature.
I had a couple of ideas for the challenge and was thinking about some of the winters in Canada. So I decided to go with a small selection of winter photos.

Ice thick enough to drive on. A section of frozen marsh at Little Quill Lake in Saskatchewan, Canada at dusk. It was -40° when the photo was taken. -40° is the same in Celsius and Fahrenheit.

Snow storm. This snow fell in a couple of hours on a Christmas Day morning. Taken on the South Bruce Peninsula, Ontario, Canada, there was another 4 inches of snow during the rest of the day.

Frazil ice on Lake Huron. What looks like water in the foreground is frazil ice. When it is cold enough to start freezing water but wave action stops the water freezing solid frazil ice forms. Think of it as a thick, slushy ice.
