Loadings from Michigan and Ohio quarries decreased almost 19 percent from a year ago. Shipments from quarries in Ontario, Canada, total 1.8 million tons – a decrease of 3.8 percent.

U.S. ports involved in the Great Lakes limestone trade are located in Calcite, Michigan; Cedarville, Michigan; Drummond Island, Michigan; Marblehead, Ohio; Port Inland, Michigan; and Presque Isle, Michigan.
