Ontario Provincial Police are asking for the public's help to identify the body of a man investigators believe had travelled throughout Canada, the U.S., and possibly Costa Rica.

The body was found on Sept. 5, 2001, at a rest area of a remote cross-country ski trail near Deep River, Ont., west of Ottawa, OPP said in a media release issued Friday.

The cause of his death isn't suspicious and foul play isn't suspected, OPP said.

Investigators have not been able to identify him.

The man was wearing a blue Eagle Creek nylon knapsack that contained hiking items including a candle, lantern, mini flashlight and a water container.

Police also found:

A Levi's pocket watch with a blue face and built-in compass.

A luggage tag from a Costa Rican domestic airline.

A laundry bag from the Sutton Place Hotel in Toronto.

Matches from Sheraton Hotels, W Hotels and the Barclay Hotel in Vancouver.

Protein bars from a GNC store.

He is described as a white man, five feet four inches tall, weighing 130 pounds with a slim build. He had good dental hygiene and no tattoos or scars. OPP said he was also "in good physical health" prior to his death.

The man was wearing size 30 Pepe blue jeans with a button fly, a black leather Calvin Klein belt, a medium-sized Fundamentals T-shirt, Replay black running shoes (fairly worn), black cotton underwear and a silver ring with an aqua-coloured stone on the pinky finger of his right hand.

He was also wearing glasses designed for near-sighted people.

The Upper Ottawa Valley OPP crime unit is investigating. Anyone with information is asked to call the unit at 1-613-735-0188 or 1-888-310-1122.
