[I8Julwg63Ew] Health Updated on August 07, 2026 EDT — Published on August 07, 2026 EDT The lock system at Sault Sainte Marie, Michigan, is the busiest in the world by cargo tonnage. Around 80 million tons of freight pass through every year — including almost all of the iron ore that makes American steel. The locks use no pumps. They work entirely by gravity, using 22 million gallons of water per transit to raise or lower ships 21 feet between Lake Superior and the lower Great Lakes. One lock chamber — the Poe Lock, rebuilt in 1968, designed to last 50 years — handles every modern thousand-foot freighter that enters or leaves Lake Superior. There is no alternative route. A government study found that its failure would produce unemployment rivalling the Great Recession. The Petoskey stone, which people collect on Michigan's beaches, is a 350-million-year-old fossil — the remains of a colonial coral that lived in a shallow tropical sea that once covered the entire state. Michigan used to be underwater and tropical. The rocks washing up on the shore are the proof. These are 30 wild facts about Michigan. We count down to Fact 1. Michigan has more freshwater coastline than any other state, is the only state in the contiguous US split into two separate landmasses, and is home to the oldest continuously running predator-prey study in the world. The most important thing hiding in Michigan is a gate between two water levels that the American steel industry cannot function without. We are Unreal Earth.
