After the deserts of Utah and Romania, a mysterious metal block continues to appear on the top of a mountain in California

A mysterious metal mass suddenly appeared on the top of a mountain in California with a similar shape to the one that appeared and disappeared in the Utah desert.

A silver metal block was suddenly discovered in Pine Mountain in the town of Atascadero, on the central coast of California, USA. The appearance of this mysterious metal block has attracted dozens of locals to climb to the top of the mountain to see and take pictures to post on social networks, the Guardian said.

“The three-sided metal block seems to be made of steel, more than 3m high and 45.7cm wide. The metal blocks are welded together at each corner and rivets are used to attach the steel plates to the frame,” local newspaper Atascadero News reported.

This metal block is only placed on the surface, not firmly attached to the rock like the metal block that appeared in the Utah desert. It has not been determined whether this metal block is the same one that was discovered in the Utah desert and then disappeared.

Not long after the mysterious metal mass disappeared from the desert in Utah, a similar metal block appeared in Romania. But this metal block is made quite crudely and is not as smooth as the one that appeared in the Utah desert.

Who created the metal blocks and placed them there is still a mystery, but their appearance in various locations has led to many speculations about the appearance of aliens. Experts claim they are man-made products, but it is unclear what their purpose is.
