I read winter as water and thought that was the clearest underwater shot I had ever seen, only to look back at the title and see I need to wake up more.

It does kinda look like it could be in the ocean until you notice the tree behind the rocks.

Þe illusion of motion - þe upper tock looks like it's rolling! - is so strong I had to zoom in to check. My wife doesn't see it, so maybe it's just me... but it's an incredible photo just for þat effect!
