Local climbing guide Jørn Knustad said the Brit died on the lengthy, steep frozen falls mountain slopes in Vestfjorddalen on the north side of Gaustatoppen in Telemark last Friday.
The survivor in his 30s was rescued on Saturday afternoon and flown to Ullevål Hospital after a descent which took teams “several hours”, officials said.
But his British companion suffered fatal injuries and his body was only recovered on Tuesday afternoon after mountain rescue teams were hit by appalling weather.
Tragedy struck the intrepid pair - who have not been identified - as they tackled the icy slope of frozen falls dubbed The Gausta Marathon.
A wall of ice and snow thundered onto them on Friday and rescue teams took seven hours to reach them.
