I spent a day in Austria at the end of my Somersault trip last summer. My wonderful Airbnb host Monika took myself and 15 elderly Austrians on a hike that passed by 4 glacial lakes. I was the youngest by 30 years and the only English speaker. There's a certain learned contentment that comes with being an outside observer. The white lines carving the mountainsides were streams of pure glacier water termed "glacier milk"; from a distance the water appears white.
