When people hear “South Dakota,” Mount Rushmore usually comes to mind. But this Midwestern state has far more to offer. From natural wonders and historic landmarks to quirky attractions and unique traditions, South Dakota is full of fascinating facts that make it truly one of a kind.
Let’s take a closer look at some of the most interesting things about the 40th state to join the Union.
Mount Rushmore: The Nation’s Stone Monument
Mount Rushmore is South Dakota’s most iconic landmark. Located near Keystone in the Black Hills, it features the 60-foot faces of four U.S. presidents—George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln.
The project began in 1927 under sculptor Gutzon Borglum and was completed in 1941 by his son Lincoln. Amazingly, no deaths occurred during construction despite the hazardous work. Each year, nearly two million people visit this colossal tribute to American history.
Tourism: A Major Economic Driver
Mount Rushmore helped launch South Dakota’s tourism industry. Today, tourism is the state’s second-largest industry, drawing millions annually. Popular destinations include the Black Hills, Badlands National Park, Custer State Park, and historic Deadwood.
Sioux Falls: The Largest and Fastest-Growing City
Sioux Falls, located in the southeast corner of the state, is South Dakota’s largest city. With a population of over 190,000 (as of 2023 estimates), it continues to grow thanks to a strong economy and no state corporate income tax.
Originally settled by Native Americans, Sioux Falls was later claimed by French explorers. It became a city in 1876 and saw major growth during the economic boom of the 1880s. The 20th century brought more development in agriculture, banking, and communications.
Rapid City: The Gateway to the Black Hills
Rapid City is South Dakota’s second-largest city. It sits at the foot of the Black Hills and serves as a base for tourists visiting Mount Rushmore, Badlands National Park, and Custer State Park. The city also hosts cultural sites like the Journey Museum and a series of downtown statues called “City of Presidents.”
South Dakota State University
Founded in 1881, South Dakota State University (SDSU) in Brookings is the state’s largest and second-oldest university. It offers over 200 academic programs and is known for its research in agriculture, engineering, and nursing.
The Capitol in Pierre
South Dakota’s capital city is Pierre. The Capitol building was constructed between 1905 and 1910 in a blend of American Colonial and Renaissance Revival architecture. Designed by C.E. Bell and M.S. Detwiler, the Capitol features marble staircases, ornate murals, and a stunning rotunda.
Natural Wonders
South Dakota boasts several natural landmarks that are both beautiful and scientifically significant.
Wind Cave National Park
Located near Hot Springs, Wind Cave is one of the world’s longest and most complex cave systems. It’s especially known for its rare boxwork formations—thin blades of calcite arranged in honeycomb-like patterns.
Badlands National Park
This park features striking landscapes with layered rock formations, deep canyons, and towering spires. It’s a fossil-rich area where scientists have discovered ancient mammal remains.
Harney Peak (Now Black Elk Peak)
At 7,242 feet, Black Elk Peak is the highest natural point in South Dakota and the tallest summit east of the Rockies. It’s located in the Black Hills and offers stunning panoramic views.
The George S. Mickelson Trail
This 109-mile rail-trail stretches from Edgemont to Deadwood. Built on an old railroad bed, it offers a scenic route through the Black Hills for bikers, hikers, and horseback riders. The trail also has about 9 miles of additional branch routes.
The Corn Palace
Located in Mitchell, the World’s Only Corn Palace is a one-of-a-kind building adorned with murals made from corn and other grains. Built in 1927 with additions in 1937, it serves as a community center, concert hall, and tourist attraction. New corn designs are created each year, attracting thousands of visitors.
Gold Mining in Lead
The Homestake Mine in Lead was the largest and deepest gold mine in North America. It produced around 40 million troy ounces of gold before closing in 2002. Today, the site is home to the Sanford Underground Research Facility, where scientists study dark matter and neutrinos deep below the surface.

The State Flag
South Dakota’s current flag features a sky-blue field with the state seal in the center. Surrounding the seal are golden sun rays and the text “South Dakota” and “The Mount Rushmore State.”
Earlier versions of the flag included different background colors and a simpler design. The current version reflects the state’s pride in its natural resources, industries, and tourism identity.
Rodeo and Western Heritage
Rodeo is South Dakota’s official sport. Events include bronc riding, steer wrestling, and barrel racing. Rodeos celebrate the state’s cowboy culture and rural roots, and they’re especially popular in summer festivals and county fairs.
Religion and Growth
South Dakota has a strong faith community. One notable example is a large congregation in Sioux Falls, founded around 1919. Today, that church serves more than 2,000 members and continues to grow along with the city.
Economic Contributions from the Military
Government spending plays a major role in South Dakota’s economy. Ellsworth Air Force Base, near Rapid City, is the state’s second-largest single employer, supporting over 8,000 jobs. The base contributes significantly to the local economy and national defense.
