National Parks Traveler Episode 116: Diving Into The National Park System

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.
