Diane Gay Jaspersen, 22, of Calgary was last seen on August 16, 1978, near Hope, British Columbia. She was hitchhiking to a friend’s cabin on Vancouver Island to attend a festival, having travelled from Okanagan Falls with the goal of reaching Parksville. A Royal Canadian Mounted Police highway patrol officer was the last confirmed person to see her near Hope.

Diane was tall, six feet, with long brown hair and hazel eyes. She was travelling with her German shepherd, Jack, and carried a small green cotton packsack. She wore blue jeans, a plaid jacket and hiking boots; she had pierced ears and a pierced nose and was pigeon-toed in both feet. Neither Diane nor Jack ever reached the cabin or the festival, and both were never found.

The disappearance remains unsolved and the circumstances of that highway sighting are a central unanswered detail. Did anyone see Diane or Jack after August 16, 1978, or know where she intended to ride from Hope toward the coast?
