A teenager was pinned for hours and was nearly unconscious for a time as rushing waters trapped his leg between his damaged canoe and rocks after he descended a waterfall near the Minnesota-Canadian border, authorities said Wednesday.
Rescue personnel freed the injured 15-year-old at the bottom of Upper Basswood Falls late Tuesday afternoon, but it was another two-plus hours before the teen was airlifted out of the Boundary Waters Canoe Area Wilderness (BWCA) by a State Patrol helicopter and eventually taken to a hospital in Ely, Minn.
The teen, whose name has not been released, was being treated Wednesday for "crushing injuries" to a leg and hypothermia, said Lake County Sheriff Carey Johnson.
"They were afraid they were going to lose him," Johnson said of two fellow canoeists who came away unscathed when they went over the 25- to 30-foot falls late Tuesday morning. The teen and his companions were in one of at least four canoes from a church group in Rochester, the sheriff said.
The force of the cascading waters pressed the mangled canoe against the teen's leg, pinning him on the rocks, Johnson said.
Upper Basswood Falls "is one of the most dangerous places" in the BWCA to navigate, he said. It is a tempting place for canoeists and boaters to catch a thrill, rather than portage around it, he said.
The sheriff said he has heard a "couple of different stories so far" about whether these canoeists intended to ride down the falls, which Johnson described as a series of rapids.
Rescuers determined that the teen became trapped sometime between 10:30 and 11:30 a.m., but the lack of cellphone service in the area kept them from calling for help.
