The Kosi River in the Himalayas once captured part of a tributary: the Arun River. It set off a chain of geological events that reshaped — and is still reshaping — the landscape, a new study ...

(CNN) — Thousands of years ago in the Himalayas, a river ate a smaller river and gave an unexpected boost to Everest’s height, scientists have discovered. Mount Everest, or Chomolungma ...

The Arun River basin is 47 miles from Everest and runs down into the larger Koshi River system – a waterway many adventurers heading for Everest base camp will traverse en route.

Loss of landmass in the Arun river basin 75km (47 miles) away is causing the world’s highest peak to rise by up to 2mm a year, University College London (UCL) researchers said.

In an expedition to the region, the scientists also found ancient lake sediments in the Arun River Basin, hinting at differences in water distribution millions of years ago.
