Harbor View

When Michigan Limestone's Calcite Plant opened in 1914, it took over 35 hours of backbreaking shoveling to load a small ship with just over two tons of limestone. Today, a massive modern freighter can be loaded with 25,000 tons of stone in eight hours or less. At Harbor View, you can get a close-up view of the huge freighters as they load limestone destined for ports all around the Great Lakes. Harbor View is located on the grounds of the world's largest limestone quarry and is open from 8 a.m. until dusk during the Great Lakes shipping season.
