Tiina Törmänen Found a Magical, Secret Lake in Finland

“I found this small lake in my first year of diving,” the photographer Tiina Törmänen tells me of this remote and secret place in Finland. “The pink algae was just so weird, and I had never seen anything like it before. That first time, it even felt a bit scary. Visibility was maybe seven to ten meters, so I couldn’t see what was in front of me.” As she swam, long ribbons of rose-colored algae appeared out of nowhere, like the arms of a ghost. As she moved, they broke apart as easily as swirls of dust.
