Mount Everest’s summit the highest place on Earth was once underwater, resting at the bottom of an ancient ocean.
It sounds unbelievable, but it’s true: the peak of Mount Everest, towering 29,032 feet above sea level, was once part of the Tethys Ocean floor. Millions of years ago, what we now call the Himalayas didn’t even exist. Instead, Earth’s shifting tectonic plates caused the Indian plate to collide with the Eurasian plate forcing layers of seafloor rock to crumple and rise, eventually becoming the Himalayan mountain range.
To this day, geologists can find marine fossils embedded in the limestone near Everest’s summit remnants of ancient sea creatures that once swam above what is now the world’s most iconic peak. These fossilized shells are physical proof that the top of the world was once submerged in saltwater.
It’s one of the greatest transformations in Earth’s history: from ocean floor to sky-piercing summit. Everest isn’t just a mountain it’s a vertical time capsule.
