Big ship diary
The gravel in your driveway, the steel in your car, and the coal that produces electricity for your home may well have spent time on a Great Lakes freighter on its way to you. At the height of the steel industry, bulk ore ships were in bumper to bumper traffic on the Great Lakes. Shipping may seem an outdated mode of transportation, but it's still by far the most efficient way to transport bulk material. Each year, over 100 million tons of iron ore, coal, limestone and other products travel through the Great Lakes navigation system by boat.
Last November, radio producer Allison Swaim spent nine days aboard a bulk ore ship called the Calumet. It's a huge ship. At 630 feet, it's longer than two football fields and holds close to 20,000 tons of cargo. You'd need almost 1,000 semi-trucks to carry the same load.
Seventeen crew members live and work on the ship for a month at a time. It's a working boat, and the work never stops. When they're not loading or unloading thousands of tons of rocks into and out of the belly of the ship, they're headed full speed through the lake to the next dock. Then, both pick-up sized engines are at full throttle and the whole boat shakes and rattles.
Allison boarded the ship at a limestone quarry in Marblehead, Ohio, just west of Cleveland, and got off nine days later in South Chicago. This route took the Calumet from Lake Erie up the Detroit River, across Lake Huron, through the Straits of Mackinac, and back and forth across Lake Michigan.

As part of Front and Center's series covering the Great Lakes region, Allison produced this audio documentary to tell the story of life on board a big ship on the lakes.
