The Erie Canal was mocked as a big ditch when it was started, but by the time it was completed in 1825 it was called an engineering marvel. Readers learn how engineers overcame a rise in elevation of 568 feet between the Hudson River and Lake Erie with locks and aqueducts to create a waterway that changed America.
