Pulled South: What Lake Superior Did After a Man Was Swept Off Black Rocks

Clutch Justice is extending condolences to the man’s family. Police have not publicly released his name, and this article does not speculate about why he was on the rocks. The purpose here is narrower and more useful: to explain what the lake was doing that afternoon, why his body traveled the way it did, and what the public record does and does not capture about deaths like this one.

What Happened, in Order

The response drew the Marquette Fire Department, Marquette County Sheriff’s Office, Northern Michigan University Police, Michigan DNR conservation officers, UPHS-Marquette EMS, and the U.S. Coast Guard on Thursday. Chocolay Township Police and Fire joined the recovery Friday.

The Wind Built the Waves

Waves on any large body of water are a product of three things: how hard the wind blows, how long it blows, and how much open water it crosses before reaching shore. That last factor is called fetch. A north wind arriving at Marquette has crossed a large stretch of the widest freshwater lake on Earth, and on Thursday it was blowing at gale force for hours. That is how the lake produced waves in the 11 to 16 foot range and a single buoy reading of 15.5 feet.

Black Rocks sits on the outer edge of Presque Isle, an ancient outcrop that draws summer cliff jumpers, wedding photographers, and storm watchers. In calm weather it feels like a viewing platform. In a north gale it is the first solid thing those waves hit. Waves that size do not simply splash a rock face; they wash over it. Anyone standing near the edge is standing in the runup zone.

Why He Was Carried South

The most telling detail in the police account is direction. Witnesses did not describe the man being dragged straight out into open water. They described him being pulled south, out of the cove and along the coast. That is the signature of a longshore current.

When waves strike a shoreline at an angle rather than head on, each wave pushes water along the beach as well as toward it. The result is a current that runs parallel to shore inside the surf zone. The National Weather Service describes these as cross currents or lateral currents, and notes that it is unusual for a shoreline not to have at least a slight one. Wisconsin Sea Grant explains that longshore currents grow strongest when waves are high and arrive at a steeper angle, and that with breaking waves of just 3 to 8 feet, they can move at 2 to 4 miles per hour. Thursday’s waves were roughly double that height.

The geography completes the picture. From Presque Isle, the Marquette shoreline runs south past the Lower Harbor and on toward Chocolay Township and Harvey. A north gale drives waves down that coast at an angle, which pushes water, and anything in it, southward. The recovery location near Lakewood Lane sits along that same down-wind path. This is a reasonable reading of the physics, not an official finding; police have not described the drift mechanism. But the witness account, the wind direction, and the recovery location all point the same way.

The 2017 Black Rocks tragedy followed a similar path. Robert Anderson, 53, and Sarah Hall, 37, both of Iron River, were swept off the rocks on October 24, 2017, during hurricane-force winds while the park was closed. Anderson’s body was found more than three weeks later in the water about 200 yards south of the Lower Harbor ore dock, again south of Presque Isle. As of the reports announcing his recovery, Hall had not been found.

The Cold Did the Rest

Current explains where a person goes. Water temperature explains why most people cannot fight it. The National Weather Service defines any water below 70 degrees as cold enough to sharply reduce survival time, and Lake Superior in November is far below that line. Below about 660 feet the lake holds close to 39 degrees all year, and storms like Thursday’s churn that deep cold toward the surface.

This is the 1-10-1 principle, developed by thermophysiologist Dr. Gordon Giesbrecht and used by the National Weather Service and U.S. Coast Guard. The Army Corps of Engineers notes that most cold-water drowning deaths happen in the first two stages, long before hypothermia sets in. Add 15-foot breaking waves and a current moving along the shore, and the window for self-rescue effectively closes in minutes. That is also why responders could not safely enter the water Thursday: the same conditions that took the man would have endangered anyone sent in after him.

The Lake That Keeps What It Takes

Lake Superior’s cold does not end at the moment of drowning. It shapes what happens afterward, and the clearest example sits about 17 miles off Whitefish Point. On November 10, 1975, the 729-foot ore freighter Edmund Fitzgerald went down in a November gale with all 29 men aboard. The wreck lies in two pieces in roughly 530 feet of water. None of the crew’s bodies were ever recovered.

The old saying that Superior rarely returns its dead, made famous by Gordon Lightfoot’s 1976 ballad, has a physical explanation. In warmer water, bacteria inside a drowned body produce gas, and that gas eventually floats the body to the surface, usually within days. Superior’s deep water sits near 39 degrees year-round, cold enough to suppress that bacterial activity almost entirely. Without the gas, a body that sinks into deep water tends to stay down. Cold fresh water can also trigger adipocere, a waxy substance that forms on tissue and slows decomposition further.

The result is that the Fitzgerald functions less like a shipwreck and more like a sealed, refrigerated grave. A 1994 expedition to the site located human remains near the wreck. Families of the crew have long objected to divers treating it as an attraction, and Michigan law under MCL 750.160a makes it a felony to disturb human remains at a shipwreck site like this one.

Next Tuesday marks the 51st anniversary of the Fitzgerald’s sinking. The storm that took it and the gale that hit Marquette this week belong to the same season, the stretch of late autumn when Superior is coldest at depth, roughest at the surface, and least forgiving to anyone who ends up in it.

The Count Nobody Official Keeps

For a lake this deadly, the public record is thin. There is no official federal or state tally of Great Lakes drownings. Reporting by CBS Chicago noted that, without good official numbers, researchers have had to rely on statistics compiled by the Great Lakes Surf Rescue Project, a nonprofit founded in 2010 by a drowning survivor.

That group’s data shows Lake Superior averaged roughly five to six drownings a year from 2014 to 2023, a smaller number than Lake Michigan but drawn from a much smaller population along its shores. Across the lakes, the project has tracked nearly 1,500 drownings since 2010. In 2025, its founder publicly asked for donations to keep the organization running.

What the Lake Asks of the Public

Marquette police closed the park Thursday and afterward repeated a simple warning: stay away from the shoreline in bad weather, because conditions can change in seconds. Storm watching on Lake Superior is a cherished U.P. tradition, and Black Rocks is one of the most dramatic places to do it. The lesson of 2017 and of this week is that the safe distance in a November gale is much farther back than it looks. Waves that size reach well past where the water appears to end, and once someone is in, the current decides the direction and the cold decides the timeline.
