A major search for a missing 13-year-old kayaker on Lake McDonald came to a successful conclusion when the boy was found and rescued on Tuesday evening. Earlier on that afternoon, the boyâs grandfather contacted rangers and told them that heâd searched for his grandson on the upper section of the lake for an hour but hadnât been able to find him. High winds blowing at the time had churned the lakeâs surface into very rough, choppy, five- to six-foot-high waves. The boy had last been seen in a plastic kayak near the middle of the lake. Rangers began a search, assisted by personnel from Glacier Park Boat Company, the Flathead County Sheriffâs Department, North Valley Search and Rescue, and Minute Man Aviation. Boats, a helicopter and ground searchers were employed in efforts to find the teenager. Around 4 p.m. rangers found a capsized kayak near the middle of the lake. An air, land and water search continued until just after 6 p.m., when the crew of a park tour boat saw the boy on the eastern shore of the lake about a half mile south of Sprague Campground. He told the rangers that heâd been capsized by a large wave and that heâd been unable to stay with the kayak. He then swam to the far shore of the lake. He said he was so tired and cold when he got so land that he crawled into a hollow log to warm up, fell asleep, and didnât wake up for about an hour. A park medic treated the boy, recommending that he be taken to the hospital to be checked out after possibly suffering from hypothermia. The boy was wearing a properly fitting lifejacket and a âshortyâ style wetsuit.
