Mount Rushmore National Memorial
Black Hills
Keystone SD
circa 1970

Mount Rushmore National Memorial is a massive sculpture carved into Mount Rushmore in the Black Hills region of South Dakota. Completed in 1941 under the direction of Gutzon Borglum and his son Lincoln, the sculpture's roughly 60-ft.-high granite faces depict U.S. presidents George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln. The site also features a museum with interactive exhibits.

Gutzon Borglum selected these four presidents because from his perspective, they represented the most important events in the history of the United States.

Majestic figures of George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln, surrounded by the beauty of the Black Hills of South Dakota, tell the story of the birth, growth, development and preservation of this country. From the history of the first inhabitants to the diversity of America today, Mount Rushmore brings visitors face to face with the rich heritage we all share.

Mount Rushmore National Memorial is a national memorial centered on a colossal sculpture carved into the granite face of Mount Rushmore (Lakota: Tȟuŋkášila Šákpe, or Six Grandfathers) in the Black Hills near Keystone, South Dakota, United States. Sculptor Gutzon Borglum created the sculpture's design and oversaw the project's execution from 1927 to 1941 with the help of his son, Lincoln Borglum. The sculpture features the 60-foot-tall (18 m) heads of four United States Presidents recommended by Borglum: George Washington (1732–1799), Thomas Jefferson (1743–1826), Theodore Roosevelt (1858–1919) and Abraham Lincoln (1809–1865). The four presidents were chosen to represent the nation's birth, growth, development and preservation, respectively. The memorial park covers 1,278 acres (2.00 sq mi; 5.17 km2) and the mountain itself has an elevation of 5,725 feet (1,745 m) above sea level.
