Steven Thomas MacLaren, 25, was last seen June 29, 1981, in Kananaskis Provincial Park, Alberta. He planned to go hiking from the Capital Trail Crew Camp and did not show up for work on July 11, 1981, which prompted concern because it was out of character for him to miss a shift.

He is described as a Caucasian male, 5 feet 9 inches, 154 pounds, medium build, with long brown hair. At the time he went missing he was wearing a red and black sweater and brown hiking boots. The Canmore RCMP opened an investigation, but there were no witnesses to his hike or confirmed signs of his whereabouts in the extensive mountain, forest and river terrain of Kananaskis.

The case remains open and unresolved. If anyone remembers Steven, saw him in the Kananaskis area around late June 1981, or has information about his plans that week, please come forward.
