So instead we took some hasty views of the cold lake and the glaciers above it, and started walking down the valley where it would get less windy and warmer. We hoped.
On the way we got to walk over a cool curvy dam, and found some nice waterfalls. And it did get quite warm at the bottom of the valley, after we had hiked a long ways down.
I hope the via ferrata closure is temporary as it looks like a fun one going just above the green water (still a few icebergs hanging out in it also!
