In 1506, when Portugal navigator Tristan da Cunha discovered a remote island in the South Atlantic Ocean, he gave his name to it and planned to return and go ashore at a later date.

In 1506, a Portuguese navigator sailed his ship around a small island in the South Atlantic Ocean. The waters were rough and he couldn’t go ashore, so he did the next best thing.

Lake Champlain is the eighth largest naturally configured body of fresh water in the continental United States.
