This last part about the D&R canal talks about the special bridges that were needed to cross the canal and who had to take care of them. And if you're wondering if the canal is still in use, Sigrid answers that question. There's a special tribute at the end of the video for which you might want this link.

We're back on Long Island, exploring the North Shore with an outing to a wildlife refuge on one of the necks, or small peninsulas that jut into the Long Island Sound, the body of water separating Long Island from Connecticut.

Let's look at how Long Island was formed around 20,000 years ago. It has to do with a glacier that brought plenty of material along with it and left some behind when it receded.

For the final days of Sigrid's visit to the New York area, she leaves the rocky North Shore and goes south to a place she knows very well from her childhood—the beach! It's a nice place to visit even in the cooler weather.

Finally home! Sigrid talks about her trip home and how it feels to be back after a month away.

Annette talks about the Wild West, and takes us to a famous gold mining town in South Dakota that was an important part of United States history.

Annette visits the Erickson Aircraft Collection in Madras, Oregon. A highlight of the collection is a plane that appeared in a very famous movie.

Over the last two decades, the environmental crisis of Florida’s Lake Okeechobee has continued to worsen and dominate local headlines. The lake is the nation’s second largest freshwater lake, but due to years of missteps, it’s been producing massive amounts of toxic algae that have closed beaches, destroyed businesses and poisoned swimmers.

Florida might seem like paradise, but water contamination is a big problem, affecting not only the environment, but businesses and the health of the residents.

Agricultural and corporate interests have long dominated Florida legislature, despite protests from residents and a substantial threat to civilians.

Bunny Wailer and other other one-time bandmates of reggae legend Bob Marley recall the rough and tumble early days of the band in Kingston. This is a must-see for all reggae fans, especially the soulful a capella chorus of "Small Axe" sung by Bunny at the end of the video!

The East Coast of the United States of America stretches from the tropical blue seas and white sand of Florida’s Sunshine State to the Canadian border in the North. We begin our journey in the warm and relaxed islands of the Florida Keys, where modern-day treasure hunters are still at work, hunting for sunken Spanish gold.

When the Fisher family of treasure seekers finally struck it rich, the local authorities tried to claim the bounty for themselves, and the case went to the Supreme Court. We learn how the “Florida Keys” got their name, and how these small outlying islands are linked to the mainland.

The town of Marathon in the Florida Keys is home to a unique hospital dedicated solely to caring for sea turtles. Marine biologist Bette Zirkelbach tells us about the dangers that sea turtles face in the wild. A lifesaving operation takes place, and a turtle is treated for a mysterious viral infection.

The only coral barrier reef in the United States surrounds the Florida Keys archipelago, and has been badly damaged by environmental pressures including ocean warming. The Coral Restoration Foundation is dedicated to its salvation, and in underwater nurseries, new coral is being grown to replenish the reef.
