I have used much time that I have had off work the past few months catching up on this and other similar projects (I try to stick to two or less, sometimes successfully).
I entered a search on FamilySearch Wiki, one of the LDS databases and found a short biography of Peter N Garff in Utah Pioneer Biographies, vol 34, page 62-63. The pages were stamped as the book was compiled so some are weak and others misplaced, but the biographies follow the alphabet fairly well within the volume.
A story I had not read before retells the event during Peter Garff's mission to Norway. Son Orson had attended a funeral in Preston, Idaho when he was approached by one Soren Jensen, who having heard his name asked his relationship to Peter, stating "I was a missionary companion to your father."
He then went on to tell how they were sent to visit a member family that lived in a valley some miles away and over a mountain range, "like going from Logan to Bear Lake". It began to snow and the trail became difficult to travel. The two missionaries became troubled and Elder Garff turned to his companion and asked how his faith was, which Elder Jensen admitted was very weak at that moment.
"He turned, then moved away from me some twenty steps and then in the name of the Almighty, rebuked the storm and commanded it to cease lest we perish. Immediately the storm was over." After several hours of plodding over the mountain they reached their destination, "completely give out." Mr Jensen, even those years later, still held the belief that if it had not been for Elder Garff's strong faith they would not have made it through.
The biographer notes that she later discovered in Peter Garff's Patriarchal Blessing was the promise of such faith as could control the elements. This biography was presented by Hazel Puehn in October 1951.
