45 Historical Photos That Give Us a Unique Glimpse Into the Past

The construction of Mount Rushmore is an extraordinary feat of human engineering and artistic achievement. Carved into the side of a mountain in South Dakota, the sculpture depicts the faces of four American presidents: George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln.

The task of sculpting the faces of these iconic figures was monumental, requiring a team of nearly 400 people to work on the project for almost 13 years. The team used dynamite and jackhammers to remove huge rock sections, which stand today as one of the great American monuments.
