Southeast Alaska is known as the Panhandle:

It's a long, narrow strip of mainland coastline, plus 1,000 islands and the braided waterways that surround them.

In most places, there are no roads connecting the communities there, so Alaskans depend heavily on ferries: the Alaska Marine Highway System.

If you fly into Haines, Alaska, you'll be on a prop plane so small that your pilot will call the roll.

"Melissa." Yup. "Mary." Yes. "Joseph?" Right here.

Just 2,500 people live in Haines — a small town in southeast Alaska surrounded by water. The scenery is incredible, with snowy mountains and lush green forest beyond. The city center is just a few blocks, with several bars, a few restaurants and a beautiful, award-winning library.

What happens to a town when a key industry collapses?

Sometimes it dies. But sometimes it finds a way to reinvent itself.

Case in point: Ketchikan, Alaska, where the demise of the timber industry has led to a radical transformation.

Many people who used to earn their livelihoods through timber have now turned to jobs in tourism.

It's an identity shift that makes the city far different from what it was in the logging heyday.

"It was this boomtown!" says longtime Ketchikan resident Eric Collins. "It was just a crazy, wild frontier place."

In rural Alaska, providing health care means overcoming a lot of hurdles.

Fickle weather that can leave patients stranded, for one.

Also: complicated geography. Many Alaskan villages have no roads connecting them with hospitals or specialists, so people depend on local clinics and a cadre of devoted primary care doctors.

I followed one young family physician, Dr. Adam McMahan, on his regular weekly visit to the clinic in the village of Klukwan.

Before we headed out on our latest road trip for the Our Land series, we put a call out on social media, asking for ideas of places we should go in Arizona and New Mexico. Shannon Miller's suggestion really caught our attention: "White Sands are the only white gypsum 'sand' dunes in the world. They are actually crystals and it is beautiful."

How could we resist?

There's really no place like it on the planet: White Sands National Monument in southern New Mexico. It's the world's largest gypsum dunefield, miles and miles of stunning white landscape.

Depending on where you sit, the U.S.-Mexico border is:

a) a dangerous frontier that allows drug traffickers and illegal immigrants to cross freely into the U.S.

or

b) a familiar frontier that is navigated as a regular part of everyday life.

For people who live along the border in the twinned cities of Nogales, Ariz., and Nogales, Mexico, it's nearly always the latter.

The sister cities are known collectively as Ambos Nogales, or "Both Nogales."

Think about the avocados you mash for your Super Bowl guacamole, or the fresh tomatoes you enjoy in the winter. There's a good chance they came from Mexico.

Our southern neighbor is the United States' leading supplier of fresh produce, providing 70 percent of the fresh vegetables we import and more than 40 percent of our fresh fruit imports. That trade has boomed since NAFTA — the North American Free Trade Agreement — was signed in 1994.

Think of the Mississippi Delta. Maybe you imagine cotton fields, sharecroppers and blues music.

It's been all that. But for more than a century, the Delta has also been a magnet for immigrants. I was intrigued to learn about one immigrant group in particular: the Delta Chinese.

To find out more, I travelled to Greenville, Miss., a small city along the Mississippi River. I meet Raymond Wong in Greenville's Chinese cemetery, right across a quiet road from an African-American cemetery. Wong's family has long been part of a thriving — but separate — Chinese community.

We hear a lot about U.S. companies laying off workers and shipping jobs overseas.

So, amid the global pressures to downsize, how do you hang onto your workforce?

We went looking for answers in Chelsea, Mich., home to a family owned manufacturer that's managed to thrive over four generations, since the company's founding in 1907.

The Chelsea Milling Co. is better known as the manufacturer of Jiffy baking mixes. You know the ones. They come in those signature little blue and white boxes: mixes for muffins, cakes, pie crusts, biscuits, brownies and more.

Teddy Roosevelt proclaimed it "The Jewel of the Delta."

Booker T. Washington praised it as a model of "thrift and self-government."

Mound Bayou, in the Mississippi Delta: a town founded in 1887 by former slaves, with a vision that was revolutionary for its time.

From the start, it was designed to be a self-reliant, autonomous, all-black community.

For decades, Mound Bayou thrived and prospered, becoming famous for empowering its black citizens. The town also became known as a haven from the virulent racism of the Jim Crow South.
