This is Flathead Lake in northwestern Montana, USA. The water is so transparent that it seems that this is a quite shallow lake. In fact, it is 370.7 feet deep.
I’ve been there & swam there and it was so gorgeous, I loved it.
I’ve been there too it was so fun and beautiful! I wanna move there when I’m older:)
