Apparently, there's an 11-foot white marble cross with a life-sized statue of a crucified Jesus Christ laying at the bottom of Lake Michigan. The statue was crafted in Italy in 1956 after being requested by a family who lost their 15-year-old son to a tragic accident.
Sadly, the crucifix was damaged on its way from Italy to the US and the family refused to take it. Instead, it was sold to a diving team and lowered into the lake as a memorial to divers who passed away.
