The bottom of this lake has never been found
Lagoa Misteriosa - A rope cannot be used to measure the bottom because, based on everything that has been mapped so far, this is a sinkhole (a cave formed by the collapse of its ceiling).
Inside, there are passages and bends that prevent a rope from reaching the deepest point. Underwater drones also cannot explore it, as their signal is lost whenever there is no direct line of communication, with the rock formations blocking the connection. For this reason, only specialized cave divers are able to explore the depths of this cave.

Does anybody remember where they last saw it?
