AMount Rushmore
Carved into the granite face of a mountain in South Dakota, Mount Rushmore features the heads of four U.S. presidents: George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. It was completed in 1941 and symbolizes the birth, growth, development, and preservation of the country. The project took over 14 years and involved hundreds of workers using dynamite and drills. Although it's admired for its artistic scale, some debate surrounds the monument due to its location on land sacred to Native American tribes.
