The Radio Free Europe/Radio Liberty recently shared a video about a unique natural phenomenon in a village called Dinoša, located in southeastern Montenegro—a small country on the Adriatic coast. There is a mulberry tree standing in the meadow there that turns into a fountain whenever it rains heavy. From a hollow on the tree trunk water can be seen gushing abundantly.
Apparently, the rains had flooded the underground springs and the additional pressure created pushed water up the tree trunk through cracks or hollows on the trunk, until it poured out of a hole a few feet above the ground. As you can see from the video, the ground is quite sloppy indicating the amount of groundwater there is in the soil and below. You can also see water gurgling out of other holes in the meadow. The entire area is flowing like a small stream.
According to a local man interviewed, this has been happening for the last 20-25 years or perhaps even longer. He estimates the tree is over 100 to 150 years old.
