How deep is Croatia in the eyes of the earth?

The depth of the Eye of the Earth in Croatia is150m.

Cetina river spring, also known as the eye of the earth, is an incredible karst spring located at the foot of Dinara Mountain. Croatia's Eye of the Earth is named because it looks like a blue-green longan from above.

The Eye of the Earth in Croatia is about 250m long, 360m wide and150m deep. The Eye of the Earth in Croatia is a cave and a national tourist attraction in Croatia.

Precautions for Eye of the Earth:

Croatia's Eye of the Earth belongs to a karst spring, where groundwater rises to the surface in karst areas. This source is called "topf" because of its conical or inverted bowl/bowl shape. This kind of karst spring is generally the area where the cave drainage system reaches the surface and connects with the cave system from its bottom.

For a karst kingdom, the most mysterious and magnificent is not only the wonderful landscape on the ground, but also the water world hidden underground. Under Adinala Mountain, a karst mountain range dominated by limestone, there is such an underground river skylight as deep as 100 meters, which is like the blue eyes of the earth, and constructs a secret world with unique aesthetic feeling.

Karst karst landform is a landform where rocks are easy to dissolve, and it will dissolve when it meets water. Therefore, the land formed by karst is a land with constant dissolution, strong leakage, full of cracks and no water left. As a result, the water here often collects underground. Whenever the water volume soars and the groundwater gushes out, it will collect the groundwater to the ground through the hole opened on the surface, that is, the skylight, forming a river on the ground.
