Wreck Location Map
Vessel Type
A sizable three-masted schooner tailored for Great Lakes freight trade, especially bulk cargo like lumber or grain. After construction, she underwent modifications—including shortening, rebuilding, and rig alternations—to adapt to evolving freight demands and sail-handling needs.
Description
The Iver Lawson was a wooden-hulled schooner designed for the transportation of bulk goods across the Great Lakes. Her construction and subsequent modifications reflect the changing needs of maritime trade during her operational years.
History
- 1869, May 4: Enrolled at Chicago; sustained collision damage soon after
- 1871–1888: Changed ownership (Lawson et al to Johnson)
- 1882: Underwent rebuild and was shortened by 2 ft
- 1888, Apr 18: Rig updated to three masts
- 1891, Apr 4: Remeasured to reflect final dimensions and tonnages
- 1904, May: Owned by Henry Larson, Chicago
- 1905, Oct 19: Struck ground in Horseshoe Bay in a fall storm and grounded
Significant Incidents
- Grounded during a storm on October 19, 1905, in Horseshoe Bay.
Final Disposition
After grounding, the hull was stripped and broken up on the beach; the vessel was salvaged for wood and equipment but not refloated. By 1908, she had been fully dismantled.
Current Condition & Accessibility
The remains were dismantled onshore and no longer exist; no underwater hull has been documented. The site holds only historical land records rather than a physical wreck.

The Iver Lawson served over three decades of freight trade on Lake Michigan, undergoing multiple rebuilds to remain commercially viable. Her final grounding in October 1905 concluded a long career. Dismantled in situ, she left no marine remains, but her story contributes to our understanding of industrial-era schooners and their adaptability to changing trade conditions.

Notmar & Navigation Advisories
None recorded. Horseshoe Bay is a known natural harbor, but the grounding was due to severe storm action—an event still possible today, though modern forecasting reduces similar risks.
