The Mount Rushmore National Memorial is set in the Black Hills of South Dakota. The hills, called Pahá Sápa in Lakota, got their name from the dark appearance they take on when viewed from far away. Their highest peak is 7,242 feet, which is also the highest point in South Dakota. In the 1870s, the Black Hills region became the site of a gold rush, and thousands of miners flocked to the area. By 1877, the Homestake Gold Mine of Lead, South Dakota, had become the biggest gold mine in the country. The mine was in continuous operation from the 1870s until its closure in 2002.
