Female skier survives fall down Alaskan mountain

A female skier has walked away unscathed after tumbling like a ragdoll down an Alaskan mountain.

The footage posted yesterday on YouTube shows Freeskiing World Champion Angel Collinson travelling at speed down an Alaskan couloir when she appears to lose her balance and falls onto her back.

Unable to stop her rapid descent, Collinson aimlessly hurtles down the mountain for more than 30 seconds before coming to a stop. 
"I'm okay!" she calls out.

Miraculously Collinson was uninjured after the crash.
