The four figures carved in stone on Mount Rushmore represent the first 150 years of American history. The birth of our nation was guided by the vision and courage of George Washington. Thomas Jefferson always had dreams of something bigger, first in the words of the Declaration of Independence and later in the expansion of our nation through the Louisiana Purchase. Preservation of the union was paramount to Abraham Lincoln but a nation where all men were free and equal was destined to be. At the turn of the Twentieth Century Theodore Roosevelt saw that in our nation was the possibility for greatness.
