There’s a lot to see in our national parks and historic sites, including some pretty interesting things underwater. Lynn Riddick takes a look at the Submerged Resources Center, the arm of the National Park Service that locates underwater resources -- whether sunken ships or planes, old ranches or train tracks, coral reefs or kelp forests -- then documents and interprets them. Always with an eye toward their preservation. And with 3.5 million acres of Park Service land underwater, it’s an immense yet intriguing responsibility. 

Also, last week the tables were turned, and the Traveler’s Kurt Repanshek was a guest on a podcast -- the Reliable Sources podcast with CNN’s Brian Stelter.  Reliable Sources is all about the story behind the story of how the news gets made.  Brian and Kurt discussed challenges of covering the news in the national parks, why the Traveler’s coverage is unique and also more important now than ever.
