Coast Guard Sector Northern Great Lakes responded to a marine casualty in Munuscong Lake, Michigan, on March 28, 2024.

At about 1 a.m., the American Mariner, a 714-foot bulk cargo ship, suffered a marine casualty and struck the Mud Lake Junction Light with its bow. The vessel was not carrying cargo. Those aboard reported no injuries, and the vessel reported no pollution from the incident.

The vessel is anchored. Coast Guard Sector Northern Great Lakes responded with boats from Station Sault Ste. Marie, a helicopter from Air Station Traverse City, and Coast Guard Cutter Katmai Bay, homeported in Sault Ste. Marie.
