Wreck Location Map
Vessel Type
Steel-hulled Great Lakes bulk freighter designed for transporting iron ore, coal, and grain.
Description
At her 1898 launch, Superior City was one of the largest riveted steel bulk carriers on the Great Lakes. Built for iron ore, coal, and grain transport, she had a forward pilothouse, tall funnel amidships, and massive open holds (no self-unloading gear, which came decades later). She embodied the transition from wood to steel lake freighters, built for industrial efficiency and durability.
History
Service: 1898–1920, in bulk ore and coal service under Pittsburgh Steamship Co.
20 August 1920: Downbound with ~7,600 tons of iron ore. At ~9:10 PM, collided in Whitefish Bay with upbound Willis L. King.
Collision Cause: Navigational confusion — Capt. Edward Sawyer of Superior City gave port-to-port signal; Capt. Nelson of King insisted on starboard-to-starboard (he claimed haze/fog; Sawyer insisted visibility was clear).
Impact: King rammed Superior City’s port midship, crushing hull. Cold lake water rushed into boiler room, causing catastrophic boiler explosion. Vessel split in two and sank in ~2 minutes.
Significant Incidents
- Total aboard: 33 (32 crew + 1 passenger — the 2nd engineer’s wife).
- Fatalities: 29 (28 crew + 1 passenger). Most were killed instantly by the boiler explosion or sucked under by downwash.
- Survivors: 4 — Capt. Sawyer, 2nd Mate G.G. Lehnt, lookout Peter Jacobson, Boatswain Walter Richter.
- Boatswain Richter later recalled: “The King struck us just aft of midship… several of the boats were torn away while the men were trying to launch them.”
Final Disposition
- U.S. Steamboat Inspectors found both captains negligent under navigation “rules of the road” — neither slowed nor clarified signals.
- Loss valuation: Superior City ~$300,000; Willis L. King damages ~$42,500.
- Settlements: Paid by 1923 to families of the lost, considered modest compared to losses.
Current Condition & Accessibility
- Located: 1972 by diver John Steele; documented in 1980s by Tom Farnquist & Gary Shumbarger (GLSHS).
- Condition: Bow upright with pilothouse intact; stern tilted 45°; midsection obliterated by boiler explosion.
- Artifacts: Personal effects and human remains observed. 1980s artifact removal (jewelry, ship’s telegraph) caused legal disputes; now state property.
- Protection: Within Whitefish Point Underwater Preserve. Removal/disturbance prohibited under Michigan law.

The Superior City disaster remains one of the deadliest Great Lakes shipwrecks, symbolizing the risks of early steel freighter operations. Its loss revealed flaws in communication rules and whistle-signal reliance, pushing navigation reforms. Today, it is preserved as both a maritime grave and a stark historical lesson — a silent steel monument lying in Whitefish Bay.
