In his determination, the sheriff noted the three people died from multiple injuries.
He said the likely cause of the accident was a slip or fall, and there were no precautions that could reasonably have been taken to prevent their deaths.
However, the sheriff said there were concerns that Cox and Crombie were given inadequate information about the use of ropes.
He also said there had been “inadequate detailed pro-active discussions” around their levels of experience and competence before heading on to the ridge.
The inquiry heard that Fowler was a competent mountain guide with considerable experience.
Wilson said: “I would wish to extend my condolences to the families of the three deceased.
“David Fowler, Graham Cox and Hazel Crombie were all clearly very much loved, and continue to be missed.”
