The eerie "Black Hole" in Mani Desert, Greece

We are located in Mani, a historical place, special but also extremely barren. We fly near the village Desert of western Mani, which - as its name suggests - is a vast desert of stones, with only low vegetation.
This monotonous landscape, however, is suddenly interrupted by a "Black Hole". And we call it so because it is the only place that does not rise and does not see the hot sun of Mani.
We fly over the abyss which is probably called Deep Muse - from the little information available about it.
Its vertical "walls" awe and thanks to them and the great depth it has, the ideal conditions are created for a small forest inside. The humidity that is trapped there and the minimal sunshine that enters the abyss feed the unique trees in the area so that they can thrive and compete who will be able to find first above the ground.
Definitely worth studying further by speleologists to map and reveal its well-hidden secrets.
The dimensions of the "Black Hole" are about 50 x 30 meters and its coordinates are as follows:
