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.

The travel kids visit a town almost completely covered by volcanic rock some twenty years before. There’s not a great deal left of it for them to see!

It’s super hot, and Julian makes the excellent decision to keep his hands well clear!
