High winds and rough waves toppled a lighthouse beacon on Lake Michigan in eastern Wisconsin on Monday. The South Pier Light Navigational Beacon served as a navigational aid to commercial shippers.
The beacon was operated and owned by the U.S. Coast Guard, but it also served as a landmark for the hundreds of ships that use Manitowoc’s harbor each year.

Witnesses told police they saw waves hitting the beacon until it collapsed.
Manitowoc Mayor Justin Nickels said high winds blowing from the east, inland, caused the big waves.
“You talk about the gales of November, this was definitely the gales of January,” Nickels said.
He added that a nearby historic lighthouse wasn’t harmed and that the city would be looking into whether any other harborside properties were damaged.
“It must have hit just right because that beacon has been standing there for decades upon decades,” he said.
Chief Eric Olson, of the U.S. Coast Guard in Two Rivers, told the Herald Times Reporter newspaper that authorities don’t know where the tower went, but it most likely was pushed into Lake Michigan.
He said the Coast Guard will search for the beacon and will arrange for another beacon for the pier.
