A mountain that’s hidden in a sea of snow in Antarctica looks strikingly like an ancient Egyptian pyramid when viewed from above. But no human (or alien) hands were needed to build this peak — it was forged through the slow, grinding process of erosion.

The pyramidal mountain, which doesn’t have a formal name, became internet-famous in 2016, but scientists likely knew about it before then, Mauri Pelto, a professor of environmental science at Nichols College in Dudley, Massachusetts, previously told Live Science. A research base for climate scientists sits just south of the mountain in an area called the Patriot Hills, and “you can probably see this mountain from up there,” Pelto said.
