Climber dies after falling 1,000 ft near summit of Alaska's Mount Johnson and their body can't be moved due to severe weather as hiking partner suffers 'serious traumatic injuries'

A mountain climber has and died and another seriously injured after falling nearly 1,000ft from the summit of Mount Johnson in Alaska. 

The two-person team had been climbing the 8,400-foot peak in the Denali National Park on Thursday night. 

Both individuals had been roped in and were ascending a route on the peak known as 'the Escalator', a steep, technical climb on the southeast face of the mountain.

Another climbing party witnessed the fall and alerted the Alaska Regional Communication Center shortly before 11 pm.

The climbing party who saw the fall then descended to reach the two climbers, confirming that one of them had died.

Responders who arrived at the scene dug a snow cave and worked on the surviving climber's injuries throughout the night. 

The park's rescue helicopter ran a reconnaissance flight of the area at 7 am the next morning, with a mountaineering ranger being long lined to the climbers. 

Both the ranger and the injured climber were then hauled out before being taken to a separate helicopter for a flight to Talkeetna State Airport. 

Later on Friday, the park helicopter and two other rangers returned to recover the body of the climber who died. 

Severe weather and increasing cloud cover forced them to turn back, with rangers to return once weather conditions allow. 

The National Park Service said in their statement that the identity of the deceased is being withheld until family members are notified. 

Mount Johnson is notable for its north face, with over 4,000 feet of vertical sheer granite that makes up part of the Escalator. 

The mountain is located in the Denali National Park and Reserve, which is home to the Denali, the highest peak in North America, seen here
