There's only one

Image: Keith Luke

How many states share a border with just one other state? Only one! Do you know which one it is?

Correct! It's Maine. The Pine Tree State, located in the northeastern United States, shares its only state border with New Hampshire to the west. But wait! It also borders Canada (the provinces of New Brunswick and Quebec) to the north and northeast, and the Atlantic Ocean to the east.

Alaska's distance

If someone asked you what the shortest distance is between Alaska and the Lower 48 states, would you know the answer? Most people wouldn't! Well, the average distance between Alaska and the contiguous US is about 500 miles. But that's not the most interesting part. Believe it or not, Alaska is actually closer to Russia than to the mainland United States! At their closest point, Alaska and Russia are separated by just 2.4 miles across the Bering Strait.

The US-Canada border

You probably already know that, at 5,525 miles, the US-Canada border is the longest land border in the world. But there are still some fascinating details about it that many people haven't heard before.

The Haskell Free Library and Opera House (Derby Line, Vermont & Stanstead, Quebec) has an international border inside the building! You read that right: Americans enter through one door, Canadians through another. But be careful! International law requires that you exit through the same door you entered.

The largest freshwater lake

The Great Lakes —Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario— are one of the natural wonders of North America, and they also hold a world record!

That's right! The largest freshwater lake in the world by surface area is right here in North America. We're talking about Lake Superior, which is shared by both the United States and Canada.

The most densely populated state

Image: Rob Curran

Since New York City is the most densely populated city in the country, many tend to believe that, as a result, New York State is the most densely populated. However, that's not the case.

The most densely populated US state is actually New Jersey! Its small size, combined with the large population in its urban areas and its proximity to New York City, has earned The Garden State this title.

The largest US state

Image: Jacob Vizek

Most Americans know which state is the largest by area. But outside the US, some get this fact wrong!

Many people answer "Texas" when asked which is the largest of the 50 states. But in reality, Alaska is far bigger, covering about 665,300 square miles compared to Texas's 268,600. This misconception may stem from Texas's reputation as a "large state" or from the way many maps distort Alaska's true size, making it appear much smaller than it actually is.

Florida's capital

Image: Meadow Marie

Miami is not only the most densely populated city in Florida but also one of its most famous, right up there with Orlando! Perhaps that's why many people mistakenly believe Miami is the capital city of the Sunshine State. However, the capital city of Florida is actually Tallahassee, which is smaller and doesn't quite receive as much attention.

The longest river

Image: Samantha Sheppard

Measuring the actual length of a river can be tough due to the serpentine shape that these bodies of water often take. This may be why many people are unsure about which river holds the title of the longest in the US.

Well, here's the truth: At 2,341 miles, the Missouri River is the longest river in the US, though just by a small margin. In second place is the Mississippi River, which stretches for some 2,320 miles and is often mistakenly thought to be the longest due to that small difference.

New York's capital

Image: Charlize Kruger

Similar to Florida, New York State's capital city is not its largest or most famous.

Contrary to what many people think, the capital of New York is not NYC, but Albany. Although Albany is smaller than NYC, it's an important economic and political hub, and it was chosen as the state capital because of its central location along the Hudson River.

10

Large population

Image: Satyan Chawla

The United States is known for having a large population, partly due to the large size of its territory. But did you know it's also one of the most populated countries in the world? In fact, it's the 3rd most populated, coming right after India and China! There sure are a lot of us, aren't there?

Dundas Castle, Roscoe, New York

Image: Annie Spratt

Also known as Craig-e-Clair, this castle was built by Ralph Dundas in the early 20th century. It is an architectural marvel of stone and copper.

Dundas died before the castle was completed, and his wife was reportedly committed to a sanitarium shortly after. Consequently, no member of the Dundas family ever actually lived in the mansion. This has led to the "Ghost of Dundas Castle" legends, with locals claiming to see a woman in white wandering the unfinished halls, waiting for a housewarming party that never happened.

2

Rockwell House, Milledgeville, Georgia

Image: Clem Geiss

Built in 1838, the Rockwell House is a stunning example of Federal-style architecture, but its beauty is shadowed by a dark past. It was originally built for Colonel Samuel Rockwell, a prominent lawyer.

Local lore whispers about the "Rockwell Ghost," believed to be a young girl who died during a yellow fever outbreak. However, the house’s most tangible secret lies in its survival; it has endured multiple fires and periods of extreme neglect. In recent years, it has become a focal point for preservationists who uncovered hidden structural reinforcements that suggest the house was built to be an impenetrable fortress of its era.

3

Elda Castle, Ossining, New York

Image: Nitrogel

If the name David Abercrombie sounds familiar, it’s because he co-founded the clothing company Abercrombie & Fitch . But in the 1920s, he also built this granite castle, named Elda (an acronym of his children’s names), as a secluded retreat.

The castle features a network of spiral staircases and open-air porches designed to blend the indoors with the rugged wild. Its abandonment, however, is a sheer tragedy. After the family moved out, the castle was used as a research facility and later fell victim to vandals. Legend has it that a fire in the 1940s was started by squatters, leaving behind a charred stone husk that resembles a medieval ruin more than a 20th-century home.

Mongo's Castle, Memphis, Tennessee

Image: Denny Müller

A stark contrast to the classical mansions of the South, Mongo’s Castle was the passion project of Mongo Bebe, a man who built his home out of scrap stone, Ashlar blocks, and found materials.

The house is a maze of folk-art eccentricity. The builder intended it to be a community center and a symbol of African-American heritage and self-reliance. It stands today as a decaying puzzle, with many neighbors still unsure of the structural logic behind its towering, uneven walls.

Bannerman's Castle, Pollepel Island, New York

Image: Leonard G., Public domain, via Wikimedia Commons

Rising from the Hudson River, this castle was never intended to be a home; it was a giant advertisement and warehouse for Francis Bannerman VI’s military surplus empire.

In 1920, 200 tons of gunpowder and shells exploded in the castle’s powder house, blowing out a significant portion of the walls. The ground is still considered unstable due to the remnants of military munitions, and the inscriptions on the walls are actually warnings and advertisements for the Bannerman business. Do you dare visit this mansion?

Castle Mont Rouge, Rougemont, North Carolina

Image: Florian Delée

This whimsical, onion-domed castle looks like it belongs in the Russian countryside rather than the North Carolina woods. It was designed by sculptor Robert Mihaly, but he ended up abandoning the project in the early 2000s following a personal tragedy and financial hurdles.

The castle remains an "empty sculpture," filled with intricate marble work and unfinished turrets. The bizarre architectural fusion lacks a standard floor plan, making it nearly impossible to convert into a functional residence without destroying its artistic integrity.

7

Ha Ha Tonka Castle, Camdenton, Missouri

Image: Hannah McBride

Robert Snyder, a wealthy Kansas City businessman, began building this European-style castle in 1905. He wanted a retreat that overlooked the breathtaking Ha Ha Tonka Spring.

Yet, Snyder never got to see his dream finished; he was killed in one of Missouri’s first recorded automobile accidents just a year after construction began. His sons finished the castle, but it was gutted by a fire in 1942. There’s a hidden network of caves beneath the castle, which were rumored to be used by outlaws and later as a natural "refrigerator" for the estate’s kitchen.

Carleton Island Villa, Cape Vincent, New York

Image: Tama66

This once-magnificent villa was built for William Wyckoff, who made a fortune with the Remington Typewriter Company.

The Secret: Wyckoff’s dream turned into a nightmare on the very first night he stayed in the house. He suffered a massive heart attack and died in his sleep. His wife had passed away a month prior, leaving the villa to a son who had no interest in it. The house has stood empty for over 70 years, its secret being the tragic "cursed" timing that prevented it from ever functioning as a family home.

Dicksonia Plantation, Lowndesboro, Alabama

Image: Theo Bickel

Dicksonia was a quintessential antebellum mansion, featuring the massive columns and wrap-around porches synonymous with the Old South.

Unlike many plantations that were destroyed during the Civil War, Dicksonia survived the conflict only to be destroyed by a mysterious fire in 1939. Its "ghost pillars," however, remained standing long after the wooden house burned away. These towering brick columns became a haunting landmark , representing the structural skeletons of a forgotten social order.

10

Wyndcliffe, Rhinebeck, New York

Image: Peter Herrmann

This house is the literal origin of the phrase "Keeping up with the Joneses." Though often referred to as a "Mystery Mansion" by urban explorers, this is the ruin of Wyndcliffe, the estate of Elizabeth Schermerhorn Jones.

Elizabeth’s mansion was so grand and intimidating that it prompted her neighbors—including the Astors—to build even larger homes to compete. The secret of Wyndcliffe is the psychological impact of its architecture; it was built to inspire envy, and its current state of absolute decay is a poetic commentary on the fleeting nature of social status.

Cioppino

Image: James Wei

A not-so-talked-about product of the Italian influence in America, cioppino is an underrated representative from San Francisco. A tomato-based seafood stew (or a soup, depending on who you ask), it started as a struggle meal made with whatever was caught that day, and it is now a beloved dish that reflects the city’s history.

2

Fry bread

Image: Immo Wegmann

When thousands of Navajo people were forcefully displaced from Arizona to New Mexico, they were provided with meager rations for the 300-mile journey: flour, water, salt, and lard. From these scarce provisions, they created a fried dough, chewy on the inside and crispy on the outside. Originally eaten on its own, it is nowadays paired with all kinds of toppings.

3

Poi

Image: Daniel Dan

Made from steamed and mashed taro root, this Hawaiian dish can be enjoyed in several ways. Although sweeter when freshly made, it is often paired with other savory dishes. It can also be left to ferment, which gives it a more sour taste. Highly nutritious, poi has been a staple in Hawaiian and Polynesian cuisines for centuries.

4

Étouffée

Image: Stephanie Moody

Gumbo and jambalaya might be what first come to mind when thinking about Louisiana, but étouffée (meaning ‘smothered’) should not be overlooked. Thicker than gumbo —though sharing many of its ingredients—, étouffée delivers what its name promises: a rich, gravy-like, shellfish stew that smothers the accompanying rice. Depending on whether you are having a Creole or a Cajun étouffée, it may or may not contain tomatoes.

5

Crab cakes

Image: Girish Dalvi

This dish can be found all along the Atlantic coast, but its most famous iteration is associated with Chesapeake Bay, Maryland. With a history that goes back to Native Americans, modern crab cakes can be enjoyed sautéed, baked, grilled, deep-fried, or broiled, and are most of the time made with blue crab, though other crab meats can be used.

6

Clam chowder

Image: henry perks

A New England staple, this dish draws influence from British, French, and Nova Scotian traditions. Although it was not dairy-based in its origins, modern clam chowder gets its rich texture from milk or cream, and features butter, potatoes, pork, and, of course, clams. Other famous variations differ mainly in the soup base, such as the Manhattan clam chowder (made with tomato) or the Rhode Island clam chowder (made with a clear broth).

Hush puppies

A Southern classic, these cornmeal fritters became popular during the Civil War because they were affordable and versatile. Usually made plain to serve as a side dish, they can also have cheese, jalapenos, whole corn grains, and other fillings added.

8

Marionberry pie

Image: Amanda Hortiz

Oregon's signature dessert, this pie filling features marionberries, a blackberry hybrid developed in the 20th century. Compared with regular blackberries, marionberries have a deeper, more complex flavor, resulting in a sweeter and sharper pie filling. A summer staple, it is often served alongside vanilla ice cream.

9

Runza

Image: Kelsey Todd

Food from the Midwest is sometimes reduced to casserole dishes and jello salads, but it is more varied than some might think. Runza, a sandwich-hot pocket hybrid filled with beef, cabbage, and onions, is an example of how midwesterners transformed immigrant food traditions into something new. Originating in Nebraska, runzas are derived from German and Eastern European pirogs , a baked, filled dough.

Akutaq

Image: Adam Chang

Though this Alaskan delicacy is technically an ice cream, don’t expect it to be like the ice creams you are used to. Made from reindeer fat, seal oil, fresh snow, berries, and sometimes, ground fish, akutaq is a dessert, a snack, a spread, and a main dish all in one. Developed as a way to preserve fruits and animal fats, this nutrient-dense dish has everything you need to face the harsh Alaskan winters.
