The National Park Service vessel Peregrine is safely docked in Houghton, after having run aground on the north break wall at the Keweenaw Upper Entrance.
NPS officials said the mishap occurred around 12:30 Saturday morning, as the 25-foot Peregrine was transporting a visitor with a medical emergency from the island to the mainland.
A response boat from U.S. Coast Guard Station Portage rescued all who were aboard.
The Peregrine was towed to Houghton Saturday afternoon, and park officials report there was no fuel or oil discharge.
There is no further information about the park visitor with the medical emergency who was being transported.
