Niagara Falls, New York, is home to one of the most powerful natural spectacles in North America. More than 3,000 tons of water pour over the edge every second, creating a thunderous roar and a rising mist that can be felt from blocks away. Visitors can stand just feet from the American Falls at Prospect Point or take the iconic Maid of the Mist boat tour, which has operated since 1846 and now features all-electric vessels.

Mist, research stations, and penguins are just a few of the things that define the South Shetland Islands, an archipelago off the coast of Antarctica.

The archipelago has also become a popular cruise destination for tourists to the Antarctic region.
