These wonderful feats of nature are more well-known on their version in Ireland, the so-called “Giant’s Causeway“, made up by more than 40.000 basalt columns.
The explanation for their formation involves the rapid cooling of volcanic lava, and it’s no coincidence most of these were created in areas around the sea, and many of them are still on coasts.
The rapid cooling creates a geometrical fracture pattern, kind of what can be seen with dried mud on droughts:
In fact, the first geologists actually thought that these basalt columns were dried rock! There were many debates and curiously, German poet Goethe — who was also a naturalist — had his part on the discovery that basalt had indeed a volcanic origin.
But there are more things in heaven and earth, Hoagland, Than are dreamt of in your “philosophy”. And one of them is in Brazil.
Rocha told us: “I had the chance to visit the place and I have to admit that personally it’s an even more impressive experience. One may highlight the Lajedo itself, formed by a huge rock formation, hundreds of meters long and dozens of meters in height, decorated by round rocks and other organic shapes, weighing dozens of tons each. On some of them we can see rock art of pre-historic people, more than 10,000 years old.”
“But even though the area was inhabited in the past, all rock formations are natural in origin … And of those in the park, the most impressive is the ‘Saca de La‘ [“Wool sacks”]. A pyramidal structure formed by rocks piled up like bricks, around 40 meters high.”
You read it right: the formation in the image above, made of enormous blocks, dozens of meters high, is entirely natural! According to geologists, it was formed through the erosion of regular cracks in the rock, not unlike the basalt columns.
Now, those are things in Earth’s heaven and earth. One can dream about what may expect us when we finally explore the other planets personally. And those are just the surprises we may expect from nature, nothing else.
