Heinz Gamper was 28 when he was last seen on September 25, 1980, in Stony Plain, Alberta, after setting out on a planned mountain climbing trip into Jasper National Park. He failed to show up for a scheduled work shift, and was reported missing; his last known activity was heading into the park’s rugged wilderness. He had brown hair, hazel eyes and a medium build.

Jasper Royal Canadian Mounted Police led the search and investigation, but no definitive answers have been made public. Details about his planned route or the expedition’s specifics are not widely available, and publicly shared updates have not produced new information. The disappearance remains an open case and a lasting question for family and community.

Did anyone who knew Heinz or who was in Jasper around September 25, 1980, see him or recall details that could help?
