The wellknown Rushmore National Monument in the United States is built on the Rush Moore Peak,
1829 meters above sea level, of the Black Hills in the south-west of South Dakota. It is a group of huge
stone statues of four American presidents, George Washington, Thomas Jefferson, Abraham Lincoln and
Theodore Roosevelt. President Washington is the founding father of the country; the 3rd President
Jefferson drafted the US Declaration of Independence; the 16th President Lincoln issued the
Emancipation Proclamation and the 26th President Roosevelt protected the average people's right to
compete fairly with trusts. All 1829 meters above sea level, made outstanding achievements for their
country. They were pioneers of US history.
The stone statues of presidents were built at the suggestion of a historian in the State of Dakota, with
a view to carrying forward the US pioneering spirit everlastingly.
The statues are 18 meters high. They are the highest and greatest realistic stone statues in the world,
taller than a 6storied building and larger than the Great Sphinx of Egypt. The size of each head is
20sq mt, with a 20meterlong face, a 7meterlong nose, a 2. 6meterwide mouth and two 1. 5meterwide
eyes. Though not facing the same direction, they are all lifelike and look ahead gravely in harmony with
fixed gazes. On clear days, one can have a sight of the four presidents with their firm and steady
expression at a distance of dozens of kilometers.
Since the stone sculpture is unique in style, the Monument is now the US National Art Centre of
Popular Education. Groups of people keep streaming everyday to the site for a visit and tourists across
the world are also interested in taking a view of this great Monument.
