After enjoying the waterfall, we headed down towards the river, which the waterfall's stream feeds into. On the way down, we saw four cedar waxwings in the tops of several nearby trees. I could barely tell what I was seeing as I took this photo (which has been cropped but is otherwise unedited), so I was pleased at how clearly it came out.
We were soon to encounter many of these ourselves as we walked the Trout Lily trail around the east tip of the big bend in the river that gives the nature center its name.
There's my foot for size reference. These blocks were thick -- some of them as high as my knee.
I've seen ice breaking up in the Cannon River before, but never big slabs that had beached themselves like these. I was fascinated to see ice crystals seemingly calving off the big blocks like icebergs off glaciers. The crystals, or ice shards, ran vertically through the ice, rather than being in horizontal layers.
