I love looking around at remote places on Google Maps. This might be the most curious that I've found. It shows a boat heading towards a pier that leads to what looks like a cave in a mountain in the northernmost reaches of Norway. https://www.google.com/maps/@71.158088,25.7968344,498m/data=!3m1!1e3
On a second look, I think there's a switchback trail leading to the pier. Why the hell would someone put a pier there?

It starts off like German soft "ch," then turns into Russian palatalized "l."
