Mike R. Heidenreich was 20 when he left his Seattle home on July 17, 1995, for what was described as a routine camping trip and never returned. An avid outdoorsman, he took equipment that included an electric blue backpack in a metal frame and an aqua blue North Face tent. He is described as blond or strawberry-blond, with blue eyes, five feet eleven inches and about 150 pounds.

Investigators found no activity on any of his accounts after June 30, 1995, more than two weeks before he was last seen. Clothing he was thought to be wearing included a turquoise jacket, a red and blue plaid Pendleton shirt, and khaki green Eddie Bauer canvas shoes. Searches in the wilderness he was believed to have entered turned up no confirmed campsite, belongings, or witnesses, and the case remains open.

Does anyone who knew Mike or who was in the areas he might have camped remember seeing him or his gear that summer?
