The mysterious Al Naslaa Rock in Saudi Arabia is a spectacularly large rock with a complete fissure in the middle that looks like it was cut by a laser, so precise and sharp that many thought it was an alien creation.
Located in the Tama Oasis in the Saudi Arabian desert, this sandstone monolith is nine metres high and 7.6 metres wide, and is topped by a mural that has become a popular photo op.
But it is the flat cut in the middle that has attracted the most attention. Some miraculous force has precisely split the boulder in two, and the bottom of the two boulders touch the ground in such a small area that it has been presumed by archaeologists to be 4,000 years old.
Many believe it to be the work of aliens, while others believe it to be evidence that ancient civilisations also possessed ‘high technology’. After years of discussion and research, some academics have recently solved the mystery from a scientific perspective.
According to the Daily Mail, geologist Cherry Lewis of the University of Bristol said that the cracks in the Anastasia megalith are likely to have been formed by a ‘free-ze-thaw’ phenomenon, explaining that “this happens when water enters a small crevice in the rock. As the temperature drops, the water freezes and expands, causing the cracks to widen and extend, and then as the ice melts, the water penetrates deeper, a process that repeats itself over thousands, if not millions, of years until the rock finally splits”. This process was repeated over thousands, if not millions, of years until the rocks finally split”. This, combined with the wind erosion effect of the desert, had the effect of ‘sandblasting’ the windward side of the rocks to create the smooth surface that we see today.
However, Lewis also says that although the Anastasia Stone is more likely to have been formed ‘naturally’, ancient people have also used the most basic tools to create Stonehenge and the Easter Island Statue of Moai, so there is no way to rule out the possibility that it was man-made.
