You may see fast flowing streams in the summer and wonder how they can become ice covered during the cold season. The formation of ice shells is a very slow process, but it creates some physical miracles. This is one of the many freeze-up processes that can be observed along McIntyre Creek during the first half of winter.
This is how an ice cover forms in shallow turbulent creeks and streams. In this case (cold temperate climate), the ice cover is left suspended above the water and is often only partial, leaving some water exposed to cold winter air.
