Which canal's cargo was primarily coal, the Cape Cod Canal or the Chesapeake and Ohio Canal?
Chesapeake and Ohio Canal The Chesapeake and Ohio Canal, abbreviated as the C&O Canal and occasionally called the "Grand Old Ditch," operated from 1831 until 1924 along the Potomac River from Washington, D.C., to Cumberland, Maryland. The canal's principal cargo was coal from the Allegheny Mountains.
Schuylkill River The Schuylkill River ( , locally ) is an important river running west to east in eastern Pennsylvania, which was improved by navigations into the Schuylkill Canal. Several of its tributaries drain major parts of the center-southern and easternmost Coal Regions in the state. Originating from waters in the Anthracite Coal Region, millions of tons of coal enabling the iron and steel based industries of America's largest city of the day made their way down the waterway to make a great dent in the 19th-century's energy needs. It flows for 135 mi before joining the Delaware River as one of its largest tributaries in Philadelphia.
