Spring 1999 - Near New Hope (PA), Katie swims in the Delaware River at the point General George Washington crossed to spring a surprise attack on the British in Trenton in 1777. Later she chases sticks in the river and swims under the Roebling Aqueduct, the oldest structure designed by the builder of the Brooklyn Bridge still standing (NY).
Summer 2001 - At a rest stop in the bottom of a gorge, Katie gets a swim in the rapids of the Salt River (AZ), the main tributary of the Gila River. Once both rivers were navigable deep into Arizona but most of their water today is diverted for other uses. The slightly salty water comes from Saltcedar trees that grow along the banks.
Summer 2004 - Katie swims in the Gulf of St. Lawrence (PEI) at Cavendish Beach on Prince Edward Island, made famous through the writings of Lucy Mead Montgomery and her tales of Anne of Green Gables. The waters here are where the clipper ship Marco Polo, "the World's Fastest Ship" in its heyday in the 1800s, sunk in a storm. Is that a mast Katie has retrieved?
Spring 2005 - When Thomas Jefferson completed the Louisiana Purchase he authorized two great river expeditions to explore the new lands bought from France. One, the Lewis & Clark Expedition on the Missouri River everyone knows about. The other, a 500-mile journey on the Ouachita River (AR) by the Hunter & Dunbar Expedition in 1804, nobody knows about. Here Katie tests the Ouachita at Arkadelphia.
Summer 2005 - The first great national project of the United States government, the Chesapeake & Ohio Canal (MD), suffered cost overruns to build, was obsolete before it opened, never connected the Chesapeake Bay with the Ohio River and never made a profit in its nearly 100 years of operation but Katie finds it a swell place to swim.
Summer 2007 - Katie swims in Lake Michigan (MI) in the shadow of the Mackinac Bridge on its Golden Anniversary. When it opened in 1957, the Mackinac was "the world's longest suspension bridge between anchorages."Today it is the third-longest suspension span in the United States and twelfth longest worldwide.
