Creepy image from A Deadly Alkaline Lake in Africa that Turns Animals into Calcified Statues.
From This Is Colossal:
Lake Natron in northern Tanzania is one of the harshest environments on Earth. Temperatures in the lake can rise to 140 °F (60 °C) and the alkalinity is between pH 9 and pH 10.5, almost as alkaline as ammonia. Animals who enter the water are almost certainly doomed, save certain kinds of fish that have evolved to survive in such a caustic environment.
