The earthquake in Nepal caused Everest's worst ever disaster, despite the fact the mountain was 200km from the epicentre.
The quake caused multiple avalanches across the Himalayas, one of which hit the base camp of the world's tallest mountain.
At least 17 people died and more than 60 were injured.
