11 The Mississippi River -ThinkstockPhotos-543573074.jpg


On July 6, 1930, Fred Newton dove into the Mississippi River at Ford Dam in Minnesota. Five months and 1,826 miles later he crawled out of the water in New Orleans, Louisiana, completing what stood for 70 years in the Guinness Book of Records as the longest swim in history. In 2002, Martin Strel swam the entire length of the Mississippi – 2,320 miles – in 68 days. Congress passed a special resolution honoring his achievements.
