The experienced mountaineer tells that they were on their way down from the Karakoram mountains in Pakistan when the rockslide occurred.
I saw how a large stone hit Laura, then she was thrown against the mountain wall", she says.
From that moment on, she did not move anymore. It was impossible for me to get to where she was in a safe way. I shouted, but there was no answer.
Krauss then called for help before she finally continued down the mountain.
Pakistani authorities confirmed on Thursday to the German news agency DPA that no further attempts will be made to retrieve Laura Dahlmeier's body after she was found dead on Wednesday.
In a statement, it says that the authorities want to respect the former biathlon star's previously expressed wish that no one else should risk their life if she had an accident.
The climber Thomas Huber was part of the rescue team that reached the scene of the accident.
When we saw Laura's body, it was clear that she had left us, he says to DPA and continues:
The body lay in very difficult terrain, which would have entailed great risk for the rescue team.
Laura Dahlmeier was 31 years old.
