In the town of Aquismón, in the state Mexican from San Luis Potosí, you will find a wonder of nature, a natural abyss. The Basement of Swallows. This place is a cave of Karst origin. This unusual formation has been created from the erosion of water on a fault, which has the characteristic of having a narrower outer opening than its inner one, which makes it have a conical shape. This upper opening has a diameter of about 60 meters, and is at ground level. The bottom however reaches the maximum opening of 300 meters Su depth is 512 meters approximately.
With these characteristics, the place is used by numerous birds as natural refuge. But contrary to what their name indicates, these birds are not actually swallows. Actually are swifts. Some birds very similar to swallows, hence the confusion. It is a cave in which you can also find a kind of parrots locally known as “cave parakeets”.
Until not long ago, the Sótano de las Golondrinas has been considered the largest cavern in the world with its 512 meters deep, of which 376 are in free fall. Today it is already considered by many to be the most beautiful cavern or vertical basement on the planet.
The decline This natural abyss, in which it would perfectly hold the Eiffel Tower vertically, begins at dawn and you can watch the spectacle of the flight of thousands of swifts and parakeets flying with incredible mathematical precision in a spiral. Currently this spectacular place is considered Biosphere Reserve by the Mexican government.
