While Everglades National Park is located in Florida, the famous rock formations known as hoodoos are found across the country in Utah. Many of these tall and unique rock formations are located in Bryce Canyon National Park. They were formed due to the evaporation and erosion of Lake Claron, which existed 50 million years ago.

St. Louis’ Gateway Arch is the tallest monument anywhere in the United States, reaching 630 feet above ground. It’s also the largest human-made arch in the world. The landmark was designed by Finnish-American architect Eero Saarinen and was built between 1963 and 1965.

Kentucky's Mammoth Cave is the longest cave system in the world, with 426 miles discovered so far and many more miles thought to exist. The cave, now part of Mammoth Cave National Park, was first explored by Stephen Bishop in the 1840s.

Eleven bodies of water make up New York’s Finger Lakes. These lakes are believed to have formed over 2 million years ago during the Pleistocene Ice Age, when glaciers carved into the land. The largest of the Finger Lakes is Seneca Lake, which covers 67 square miles.

Oregon’s Crater Lake is the deepest lake in America, descending to depths of 1,943 feet — which is taller than the Eiffel Tower, Washington Monument, and Statue of Liberty stacked on top of one another. Making Crater Lake even more unique are its pure, crystalline waters that are fed entirely by snowmelt and rain.

Though Hawaii is best known for its eight major islands, the state is composed of 137 volcanic islands in total, which are scattered across 1,500 miles of the Pacific Ocean. The Hawaiian archipelago includes reefs, atolls, and islets that make this state unique from any other in the country.

Utah ranks third in national parks after California, which has nine, and Alaska, which has eight. Utah boasts five popular parks, including Arches, Bryce Canyon, and Zion. All told, there are 63 national parks in the U.S.

Nebraska is the only triply landlocked U.S. state — the quickest way to get to the ocean involves cutting through Kansas, Oklahoma, and Texas before reaching the Gulf of Mexico. There are 27 landlocked states in the country, though seven of those 27 landlocked states do have access to the Great Lakes.

Kansas is the seventh-flattest state in the country — the honor of the flattest state belongs to Florida. About 52% of Florida’s 65,758 square miles of area is flat land. Illinois is the next flattest state, followed by North Dakota, Louisiana, Minnesota, and Delaware.

There are only four time zones that fall within the contiguous U.S. Spanning from the Atlantic to the Pacific, these zones are the Eastern Time Zone, Central Time Zone, Mountain Time Zone, and Pacific Time Zone. Including Alaska and Hawaii, the U.S. has two additional time zones.

Missouri is tied with Tennessee for being the most neighborly states. Both Missouri and Tennessee touch eight other states. Missouri abuts Arkansas, Iowa, Illinois, Kansas, Kentucky, Nebraska, Oklahoma, and Tennessee. Tennessee, on the other hand, touches Alabama, Arkansas, Georgia, Kentucky, Mississippi, Missouri, North Carolina, and Oklahoma.

Tucked away in the northeast corner of the country, Maine only shares one state border with New Hampshire. Maine shares its northern borders with two Canadian provinces (Quebec and New Brunswick) and also connects with Nova Scotia across the Gulf of Maine.

Of the five Great Lakes, Lake Michigan is the only one contained entirely within the United States. The other four Great Lakes — Erie, Huron, Ontario, and Superior — are shared with Canada. Lake Michigan is nestled between Michigan to its north and east, Indiana and Illinois to the south, and Wisconsin to the west.

Mount Rushmore is carved into the Black Hills of South Dakota. Construction on the famous presidential monument began in 1927 and was completed in 1941. It features the larger-than-life likenesses of former Presidents George Washington, Thomas Jefferson, Abraham Lincoln, and Theodore Roosevelt.

The Missouri River is America’s longest river, extending for 2,540 miles. That makes it only slightly longer than the Mississippi, which flows for 2,350 miles. The Missouri River begins in Montana and traverses through four other states before culminating in St. Louis, Missouri, where it connects with the Mississippi River.

America’s largest trees aren’t located in Florida, but rather California. Sequoias are the largest tree species in the country; these massive redwoods extend hundreds of feet tall. Hyperion is the largest individual sequoia tree, reaching heights of 380 feet above ground in California’s Redwood National Park.

California isn’t the westernmost state in the contiguous United States; that honor belongs to Washington. Cape Alava, located in Washington’s Olympic National Park, is the westernmost point anywhere in the lower 48. If you include territories, the westernmost U.S. point is Point Udall, Guam.

Denali is the highest peak anywhere in the country, reaching heights of 20,310 feet, but it’s located in Alaska. Mount Whitney is the tallest point in the contiguous U.S. Part of the Sierra Nevada mountain range in eastern California, Mount Whitney reaches a height of 14,494 feet above sea level.

Of all 50 state capitals, Phoenix, Arizona, is the most populous with 1.6 million residents. No other state breaks the million mark — though Austin, Texas, comes closest with 966,000 residents. On the opposite end, Montpelier, Vermont, is the least populous state capital with just under 8,000 residents.

Though it borders New England, New York is not one of the six states that make up that region. Those six states include Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. New York is still considered a northeastern state, but it falls into the Mid-Atlantic region, along with New Jersey and Pennsylvania.

The U.S.-Canadian border is the longest international border in the world, extending for 5,525 miles across 13 states. The state of Alaska shares the longest border with Canada, stretching for 1,538 miles. By comparison, the U.S.-Mexico border is 1,933 miles long.

There are 48 states in the contiguous United States — Alaska and Hawaii are the two outliers. However, Alaska is one of 49 states located within the continental United States, as it also sits on the North American continent. Hawaii is the only state outside of North America and the only archipelagic state.

Point Barrow, Alaska, is the northernmost location in the United States. The northernmost point in the lower 48, however, is Northwest Angle, Minnesota. America’s southernmost state is Hawaii, while the southernmost location in the contiguous U.S. is Ballast Key, Florida. Including territories, the southernmost point on U.S. soil is Rose Atoll in American Samoa.

Rhode Island is America’s smallest state, covering just 1,034 square miles of land area, plus an additional 511 square miles of water area. The next smallest state is Delaware, with Connecticut, New Jersey, and New Hampshire rounding out the smallest five states. At 665,384 miles, Alaska is the largest state in the country.
