A fisherman found a 152-year-old shipwreck with his kid, thought it was nothing special, and kept fishing

• When a Wisconsin fisherman stumbled upon a 152-year-old shipwreck, he didn't think much of it.
• Tim Wollak was out fishing with his daughter in Green Bay when his FishFinder showed something unusual underwater.
• Months later, he learned that he discovered a long-lost wreck.

A Wisconsin father who accidentally discovered a 152-year-old shipwreck says when he first spotted it on his FishFinder, he assumed it was nothing special, and just kept on fishing.

Tim Wollak, a 36-year-old salesman from Peshtigo, Wisconsin, told Business Insider he made the discovery while out fishing in about 8 to 10 feet of water with his 5-year-old daughter near Green Bay's Green Island one afternoon in August.

Wollak noticed something unusual on his FishFinder sonar device, so he swung his boat around to get a better look at it.
