My last post, “Frozen Fall Creek I”, ended with macros of Ice Crystals on a bed of frost over creek ice within sight of our former home, a restored water mill. I continued on the ice, following the creek to this spot were the stream bed turns 90 degrees, changing from a southerly to a western flow.
Here I encountered an open course where constant water motion resisted freezing. A few frigid days later, the course had an amazing transformation.

The transparent ice of the now frozen space retained the impression of movement, the surface rippled by current. In the following photograph, motionless ice crystals reveal the truth.
In the intervening days, the constant motion resisted freezing while the water temperature dropped well past freezing to achieve a supercooled state. As the water temperature continued to drop, a fast transition from fluid to solid happened so quickly the movement of the water surface was preserved.
Here is the matching “after” photograph to the “before” that started this post.
