Authorities say dozens of people waded to shore and two were rescued by helicopter from a tour boat that was damaged by a wave in Lake Michigan near Sleeping Bear Dunes National Lakeshore.
No major injuries were reported.
The Coast Guard says the operator of the tour boat Pictured Rocks called for help Monday evening after a wave reportedly went over the boat's bow, smashing a window and causing the boat's electronics to malfunction. The boat had 61 people aboard.
The boat's operator told the Coast Guard he grounded the boat near the shore in Empire in part to prevent further damage.
All but two of the passengers waded to shore. The Coast Guard says two with apparent shoulder injuries were lifted from the boat by helicopter.
