In a lot of places at Raquette River in Colton, NY, we saw icy sheets forming overheads over the ice and water. In some places, you could see the layers of ice and snow, with the water peeking through deep below. The unfrozen water carves out pathways beneath the ice, allowing it to flow through even though there is frozen water above. We saw a small rodent jump and hide in one of the nooks this created, which is the one seen here. I took several pictures of this because it looks very neat, and I had never seen it so pronounced before.
