Frozen In Time – Finding and Identifying the W.C. Kimball

In 2019 a team of divers, historians and shipwreck enthusiasts found and identified a new shipwreck in northern Lake Michigan. Though the W.C. Kimball was not unlike many other schooners that sailed the inland seas during the late 1800’s, it’s the incredible condition she is in now, that makes her one of the most significant finds ever.

Diver and artist Cal Kothrade tells the story of how shipwreck hunter Ross Richardson found the Wisconsin built vessel, and of the diverse team that would eventually solve the mystery of what this sail away’s name is. Through video, photographs and artwork, Cal discusses the condition of the wreck today, and the forensic clues which led to its identification, as well as what the ill-fated ship and crew’s final hours might have been like.
