Description

edit

The vessel measured approximately 135 ft in length, with a beam of about 20 ft, and registered at 231 gross tons. Her propulsion was provided by dual side paddle wheels, typical of mid‑19th century Great Lakes steamers.[1]

History and wreck

edit

On October 8, 1850, while en route to resupply the Thunder Bay Island lighthouse, Benjamin Franklin was caught in a sudden storm and ran aground on the limestone reef at the southeast end of Thunder Bay Island. The vessel became stranded and began breaking apart. No lives were lost.[2]

Following the grounding, much of the machinery was stripped ashore. A subsequent storm on November 28 washed away all remaining hull components, scattering wreckage along the shores and underwater.[2]

The wreck

edit

Today, no intact hull remains. Machinery and hardware are widely scattered across depths ranging from 10 to 55 feet. Notable survivors at the site include: Two paddlewheel shafts lying on the lake bottom, each with cast‑iron hubs, one still containing portions of the original wooden spokes; One intact and two partially intact cylindrical boilers located in deeper water and a rudder and rudder post found closer to shore.[1]

Diver access to various artifacts, including boiler fragments, steam machinery, and paddle wheel components, reveals the destructive effects of waves, ice, and currents on the shallow reef site.[1]

GPS location of primary wreck artifacts is approximately N 45° 01.934′ W 83° 11.529′, with additional coordinates recorded for paddlewheel shards and boilers.[2][3]
