Which U.S. State Has the Shortest Coastline and Why Is New Hampshire Called the Granite State?

New Hampshire, like several other New England states, contains large deposits of granite, a very hard and durable igneous rock used as building material.

It was once a major supplier of granite to other states, and several granite quarries continue to operate there.

New Hampshire has just 13 miles (21 km) of coastline on the Atlantic Ocean, the shortest coastline of any state that borders an ocean.
