British Columbia, Selkirks, Swiss Peaks. On 17 July Donald David Wallbridge (35) apparently climbed at least one other peak in the vicinity of Rogers Peak Hermit area since he had signed the Cairn register on Sifton (9,563 feet) and had apparently also climbed Rogers Peak (10,546 feet). This was the plan he had registered at the Warden’s office. Extensive searching after he was reported overdue on 19 July failed to find any trace except tracks leading to a broken cornice on Swiss Peaks. Bad weather halted the search on the fourth day. Subsequent searches on the glacier below the broken cornice revealed nothing.

Analysis: It should be noted that the missing person apparently fell through the cornice of a peak he had not indicated he was going to climb. It was not until the third or fourth day that the search expanded to this peak. Correct registration would have led to this discovery earlier. Other mistakes are obvious.
