Last May 28th ICOD Associates gathered associates and customers for a visit to Mount Rushmore National Memorial in the Black Hills of South Dakota. Mount Rushmore National Memorial is a sculpture carved into the granite face of Mount Rushmore (Lakota Sioux name: Six Grandfathers) near Keystone, South Dakota, in the United States. Sculpted by Danish-American Gutzon Borglum and his son, Lincoln Borglum, Mount Rushmore features 60-foot (18 m) sculptures of the heads of four United States presidents: George Washington (1732-1799), Thomas Jefferson (1743-1826), Theodore Roosevelt (1858-1919), and Abraham Lincoln (1809-1865). The entire memorial covers 1,278.45 acres (2.00 sq mi; 5.17 km2) and is 5,725 feet (1,745 m) above sea level. A fact not know too many is that in 1937, a bill was introduced to Congress to add the face of Susan B. Anthony to the monument but a rider was added to the bill limiting funds to only the faces that had been started. The Monument is visited by over 3 million people each year and it took 14 years and 400 workers to complete the sculpture.
