Lake Superior lives up to its name

Image: Jacob Skowronek

Lake Superior is the largest, deepest, and coldest of the five. It holds more water than the other four lakes combined—enough to cover North and South America in a foot of water. At 31,700 square miles, it’s the largest freshwater lake by surface area in the world.

Lake Michigan is the only Great Lake entirely within the jurisdiction of the United States. It touches four states—Wisconsin, Illinois, Indiana, and Michigan—and its shores are home to major cities like Chicago and Milwaukee. As if this wasn’t enough, this lake also boasts the world’s largest freshwater sand dunes.

They create their own weather

The Great Lakes have a powerful influence on regional weather, especially through the phenomenon of "lake-effect snow." As cold air sweeps over the warmer lakes, it picks up moisture, resulting in heavy snowfall in cities like Buffalo, Cleveland, and Chicago. The lakes also generate localized storms that can rival oceanic tempests in intensity. Yet, not all is harsh; these unique conditions help create microclimates that are perfect for agriculture, supporting a range of crops across the region.

Prone to stormy and unpredictable weather, the Great Lakes are home to over 6,000 shipwrecks. The most infamous of these, the SS Edmund Fitzgerald, sank in Lake Superior during a violent storm in 1975, inspiring Gordon Lightfoot's iconic ballad. In fact, many of these wrecks are remarkably well-preserved, thanks to the cold freshwater, which slows down the decay process and keeps these sunken ships intact for decades.

The Great Lakes hold about 21% of the world's fresh surface water. That’s roughly six quadrillion gallons—enough to submerge the lower 48 states under about 10 feet of water. Given this staggering quantity, it's no surprise that the lakes are crucial to American drinking water, agriculture, and industry.

The Erie Canal’s role

Image: Lucy M

Opened in 1825, the Erie Canal linked the Great Lakes to the Atlantic Ocean via the Hudson River, transforming trade and settlement patterns. It played a pivotal role in making New York City an economic powerhouse and significantly accelerated the movement of goods between the Midwest and the East Coast. While most traffic now flows through the larger St. Lawrence Seaway, the Erie Canal remains a key chapter in U.S. history.

When the Niagara Falls stood still

Image: Vishwesh Jirgale

In 1969, engineers temporarily halted the flow of Niagara Falls due to concerns that erosion was progressing so rapidly the falls could disappear in a few years. After a thorough inspection by the Army Corps of Engineers, they concluded that no immediate maintenance was necessary. Despite this, the endeavor was far from futile—it provided valuable insights that would guide future preservation efforts for the iconic falls.

America’s forgotten "Third Coast"

Image: Richard Main

The Great Lakes coastline spans about 10,900 miles, which makes it longer than the U.S. East and West Coasts combined. This hidden "Third Coast" features sandy beaches, towering cliffs, and picturesque lighthouses, making it a popular destination for tourism and outdoor recreation.

Once an ancient ocean

Millions of years ago, the region now holding the Great Lakes was covered by an ancient sea. Over time, glaciers carved out the massive basins, which filled with meltwater after the Ice Age. The evidence of this transformation is still visible in the region’s fossils and rock formations.

Chicago River’s historic reversal

Image: Jake Leonard

In 1900, engineers reversed the flow of the Chicago River to prevent sewage from polluting Lake Michigan, the city’s drinking water source. Using a system of canals, the river was redirected toward the Mississippi River watershed, an astonishing feat of engineering that still works to this day.

Did you know Jackson, Mississippi, is named after the 7th U.S. President, Andrew Jackson? It is one of the four state capitals named after American presidents —the other three are Jefferson City (Missouri), Lincoln (Nebraska), and Madison (Wisconsin).

Jackson is the only U.S. capital built on top of an extinct volcano. Interestingly, during the Civil War, the city was burned by Union troops, giving it the nickname "Chimneyville". In addition, Jackson is best known for being the center of the civil rights movement during the 1950s and 1960s.

Santa Fe, New Mexico

Image: Wendy Shervington

In 1610, Spanish settlers established Santa Fe as the capital of New Mexico, making it the oldest state capital in the country. But that's not the only peculiarity of this quaint city with a temperate climate and a unique historical and cultural richness. At 7,000 feet above sea level, Santa Fe is also the highest U.S. capital.

3

Honolulu, Hawaii

Image: Daniel Lee

Known for its spectacular beaches and rich cultural heritage, Honolulu is the only state capital not on the North American mainland. Considered the birthplace of modern surfing, it also has the highest average annual temperature of any U.S. state capital.

But those aren't the only interesting facts about Hawaii's capital. Here are a few equally (or more) crazy ones: it hosts the only royal palace in the United States (Iolani Palace), the island is made up of volcanic soil, and it houses the world's largest open-air shopping mall (Ala Moana Center).

4

Annapolis, Maryland

Image: Terry Granger

Annapolis is a historic city on the shores of the Chesapeake Bay, known for its colonial architecture, nautical tradition, and academic value. But did you know it is also the smallest U.S. capital by land size? Just 6.7 square miles!

Annapolis was also one of the nine capitals the United States has had throughout its history. For nine months during the Revolutionary War, Maryland's current state capital served as the seat of the Confederation Congress.

Bismarck, North Dakota

Image: NASA Astronaut, Public domain, via Wikimedia Commons

If you thought Juneau, Alaska, had the lowest average winter temperature of all state capitals, think again! It's actually Bismarck, North Dakota, where the coldest temperature ever recorded was -45°F. Imagine that!

Bismarck was founded in 1872 on the banks of the Missouri River. The city was named after Otto von Bismarck, the chancellor of Germany, to attract German investors. Another fun fact? In 1930, Bismarck and Fargo had a dispute, known as the "Capitol Tower War," over which city should be the state capital.

6

Charleston, West Virginia

Image: Carol M. Highsmith, Public domain, via Wikimedia Commons

Did you know that the original name of West Virginia's capital was Charles Town in honor of the father of Colonel George Clendenin, one of the first settlers?

Charleston is best known for offering a unique combination of history, culture, and outdoor adventure.

7

Hartford, Connecticut

Image: Balazs Busznyak

Founded in 1635, Connecticut's capital is one of the oldest cities in the U.S. Hartford is known for being a key cultural center in New England. It was the home of writer Mark Twain and is home to historic sites such as the State Capitol, the Harriet Beecher Stowe House, and Bushnell Park, the oldest public park in the country.

Hartford is also called the "insurance capital of the world" due to the presence of major insurance companies. But the city's most curious fact is that it was where Teddy Roosevelt, aboard the Columbia Electric Victoria Phaeton, took the first presidential automobile ride in history!

8

Harrisburg, Pennsylvania

Image: Katherine McAdoo

Pennsylvania's capital city is best known for its role in the Civil War and the Underground Railroad. Located on the banks of the Susquehanna River, Harrisburg has been an important center of transportation and commerce. Today, it is known for its historic architecture, museums, and special events.

Harrisburg is also home to the longest stone arch bridge in the world, the Rockville Bridge, built in 1902. Oh, and in 1979, it came close to a nuclear disaster due to the accident at the Three Mile Island plant, the worst in U.S. history —but that's a longer story for another article!

Olympia, Washington

Image: Peter Robbins

Located at the southern tip of Puget Bay, Washington's state capital is known for its natural beauty and vibrant culture. But did you know Olympia is the northernmost state capital in the contiguous U.S.?

Oh, and it's also a great place to try some of the best craft beer in the country!

10

Salt Lake City, Utah

Image: Cong Wang

Utah's state capital is popular for being one of the best places to ski in the United States. But that's not all! Salt Lake City is also the only state capital with three words in its name. Have you ever thought about that?

It has the largest Mormon population in the country and is the world headquarters of the Church of Jesus Christ of Latter-day Saints. Another fun fact? Salt Lake City is home to more plastic surgeons per capita than any other state capital!

11

Montpelier, Vermont

Image: John Holm

Named after the French city of the same name, Montpelier is the least populated state capital, with a population of just 7,900. Probably for that reason, Vermont's capital prides itself on its small local businesses: it is the only state capital that doesn't have a McDonald's or a Starbucks. Could you live without these fast food chains? It doesn't have a Walmart store either!

12

Topeka, Kansas

Image: Nils Huenerfuerst

Topeka, Kansas’s state capital, has several interesting tidbits. For example, did you know its name, of Native American origin, means "a good place to dig potatoes"? Interesting, don’t you think?

In 2010, Topeka temporarily changed its name to "Google, Kansas" to attract the attention of the internet giant and become the capital city of fiber optics. Frivolous facts aside, Topeka was also very important in the history of the civil rights movement.

Arizona skips Daylight Saving Time

Image: Christoph von Gellhorn

This is partly true because most of the state doesn’t bother with Daylight Saving Time . They stopped changing the clocks back in 1967. The exception is the Navajo Nation, which stretches into Utah and New Mexico and keeps DST so all its communities stay on the same schedule. Now, as for the smaller Hopi reservation, inside the Navajo Nation, it sticks with Arizona time… Yes, quite confusing if you’re not a local.

Georgia isn’t really the Peach State

Image: Jessica Furtney

Georgia loves its peaches, sure, but the state’s top fruit money-maker is actually blueberries . In recent years, blueberries have brought in several times more cash for farmers than peaches. Meanwhile, California grows far more peaches than Georgia ever has. The nickname stuck from the old days when Georgia peaches were famous for their flavor, not their volume. So while the pride is real, the peaches aren’t quite the powerhouse people may think.

3

Nevada didn’t record the hottest US temperature

Image: tommao wang

You probably think of Nevada’s desert heat as unmatched, but the all-time record belongs to California’s Death Valley . In July 1913, it hit a mind-melting 134 degrees Fahrenheit, the hottest temperature not only in America but the hottest ever recorded on Earth!

4

Minnesota doesn’t have the most lakes

Image: Tom Conway

Minnesota proudly calls itself the "Land of 10,000 Lakes," but that’s selling itself short… The real number is closer to 12,000. However, Alaska wins this battle . The state has more than 3 million lakes over five acres in size. In fact, Alaska contains over 40 percent of the nation’s surface water. If you love fishing, kayaking, or just staring at a quiet stretch of water, the true lake capital of America is far up north.

Pineapples aren’t native to Hawaii

Image: Christian Joudrey

Pineapples are everywhere in Hawaiian imagery, but the plant actually comes from South America , mainly Paraguay and southern Brazil. Spanish explorers likely brought them to Hawaii in the 1500s after spreading them across the Pacific to places like the Philippines and Guam. Hawaii’s climate turned out to be perfect for growing them and by the 1900s, the islands were producing so many pineapples that the fruit became a symbol of Hawaii itself.

Maine isn’t the country’s easternmost point

Image: Chris Henry

If you’re a Geography geek, you’ll love this one. You might picture Maine’s rocky coast as the eastern tip of America, but the actual easternmost point is thousands of miles away, on Alaska’s Semisopochnoi Island in the Aleutians. How is that possible? Well, that’s because it crosses the 180th meridian, putting it in the Eastern Hemisphere. That means part of Alaska technically sits farther east than anywhere in Maine.

The biggest US earthquake didn’t happen in California

Image: Lala Miklós

California has suffered some big earthquakes in its history, but the most powerful earthquake in America struck Alaska in 1964 . It hit Prince William Sound with a magnitude of 9.2. It was so strong it shook the ground for four and a half minutes and triggered massive tsunamis. In today’s dollars, the damage would total more than $2 billion. Alaska sits on a collision zone of tectonic plates, making it one of the world’s most seismically active regions.

The Everglades isn’t America’s biggest swamp

Image: Joshua J. Cotten

A lot of people picture the Florida Everglades when they think of swamps, but technically, the Everglades isn’t a swamp at all. The real title of the largest swamp in the United States goes to Louisiana’s Atchafalaya Basin , which spans about 1.4 million acres. This swamp has a vast mix of cypress forests, bayous, and marshes, and it’s more than twice as productive as the Everglades when it comes to wildlife and plant life.

Big cities aren’t always capitals

Image: Mackenzie Cruz

It surprises people how often the biggest city isn’t the state capital . New York City? Not the capital… Albany is. Chicago? Nope, that honor goes to Springfield. Pennsylvania’s capital isn’t Philly or Pittsburgh, it’s Harrisburg. Even California’s capital isn’t L.A. or San Francisco, it’s actually Sacramento. Out of fifty states, only seventeen have their most populous city as the capital.

Alaska isn’t divided into counties

Image: Rod Long

Alaska likes to do things its own way. Instead of counties, it’s split into boroughs , and a massive area known as the Unorganized Borough has no local government at all. People out there don’t pay property taxes, but that freedom comes with challenges, limited services, fewer job options, and tough living conditions.
