The Mount Rushmore National memorial was started in 1927 and was finished in There were about 400 men and women who worked making the sculpture. Even that there were dangerous conditions for this type of work, no one died during the blasting and carving process. More than 90% of the excavation was performed by blasting 450,000 tons of granite, using over 20,000 Lb. of dynamite. The workers were very skilled, they could blast to within only 4" of the finished surface.
The sculptor for the project was Gutzon Borglum who selected the mountain site. At 7,242 feet, it is the highest point between the Rockies and the Swiss Alps. Borglum selected for his sculpture four great American Presidents. He believed that these presidents represented the history of the United States. George Washington represented the birth of the United States. Thomas Jefferson represented the growth of the United States. Abraham Lincoln represented the preservation of the United States, despite the horror of the Civil War. Theodore Roosevelt represented the development of the nation.
All the masks were built to a scale 1:12
The work advanced well, but there were a few problems. Jefferson's head was started on the left of Washington's head. However, the rock found there was too soft, therefore the work already performed was blasted away and restarted on the right side.

As you approach you can see the stone debris from the blasts and excavation.
Trees start growing on the top of rocks.
On top of Roosevelt's head is a type of tripod used to haul materials. The annual maintenance uses qualified mountain climbers who monitor and seal cracks. The Monument was cleaned only once, in 2005, using pressurized water at over 200°F.
