South Dakota

South Dakota is an expansive, sparsely populated midwestern U.S. state where rolling prairies give way to the dramatic Black Hills National Forest. Until 1889, North and South Dakota were one territory. The territory was named for the Dakota Indian tribe that lived in the region. Dakota is the Sioux word for “allies” or “friends.”

Mount Rushmore National Memorial is a massive sculpture carved into Mount Rushmore in the Black Hills region of South Dakota. An America's Shrine of Democracy, it features 60-foot faces of four great American presidents who represent the birth, growth, development and preservation of this country. U.S. president’s faces are George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln. Sculptor Gutzon Borglum began drilling into the 6,200-foot Mount Rushmore in 1927. Creation of the Shrine to Democracy took 14 years and cost a mere $1 million, though it’s now deemed priceless.
