Jim Morrison hopped left on his skis, sending trickles of snow down a sheer gully on the north face of Mount Everest.

Then he carefully manoeuvred to the right, his skis in a controlled slide, his breathe heavy in the oxygen-thin air.

Below him plunged 9,000 feet of snow, ice and rock — the most merciless ski run on Planet Earth.

It had never been done. The last person to attempt it disappeared on its slopes two decades ago.

Morrison, after several years of preparation, climbed what's called the Hornbein Couloir on the mountain's north face — which only five people had ever done before — and then skied down it earlier this month.

He was in part inspired to undertake and complete the feat by his former partner Hilaree Nelson, who died in an extreme skiing accident in Nepal in 2022.

Morrison's accomplishment was documented by filmmaker and mountaineer Jimmy Chin for an upcoming documentary for National Geographic Documentary Films.

Chin previously filmed Free Solo, about climber Alex Honnold's ascent of El Capitan in Yosemite National Park without using ropes.
