The search continues for a missing 81-year-old hiker in Waterton Lakes National Park one week after he was reported missing. On July 16, Bob Toothill set out to hike the Great Divide Trail from Waterton all the way to Coleman in the Crowsnest Pass. He was supposed to arrive by July 22 but never made it. His family reported him missing a day later. Toothill’s last known location was Rowe Lakes Trail on July 19. RCMP say they have narrowed down the search area and have used drones, helicopters and tracking dogs. Toothill’s family describes him as an avid outdoorsman who could easily hike up to 20 kilometres a day.
