During the 14 years of construction not one fatality occurred. Dynamite was used until only three to six inches of rock was left to remove to get to the final carving surface. At this point, the drillers and assistant carvers would drill holes into the granite very close together. This was called honeycombing.
How Many Years Did It Take to Build Mount Rushmore?
Mount Rushmore is one of the most iconic landmarks in the United States, and its construction has become part of American history. The monument is located in the Black Hills of South Dakota and features the faces of four American presidents, George Washington, Thomas Jefferson, Abraham Lincoln, and Theodore Roosevelt, carved into the side of the mountain. The site was chosen for its stunning beauty and its historical significance to the United States. It is a popular tourist destination and a symbol of national pride.
So, how long did it take to build Mount Rushmore? The process of carving the four presidents’ faces into the mountain began in 1927 and was completed in 1941. This means that it took 14 years to complete the project. However, the work was not done continuously; instead, it was done in several stages, with long breaks in between.
The first stage of the project began in 1927 when sculptor Gutzon Borglum and a team of 400 workers began to blast the mountain with dynamite in order to create the basic outlines of the four presidents’ faces. This process took almost a year and cost $450,000.
After the basic outlines were finished, the next stage was to carve the details of the presidents’ features into the mountain.
