Over 75 years ago, one of the most iconic structures in the world was created. The Mount Rushmore sculpture has four of the most respected presidents looking over America’s landscape. As anyone can imagine, building this massive structural wasn't easy and it took a lot of years and over 400 workers to complete it.
The original idea by South Dakota historian Doane Robinson was to do something to boost tourism in this mountain range. It was a brilliant idea because over 3 million people visit this iconic structure every year.
The images on Mount Rushmore are of the beloved American presidents George Washington, Thomas Jefferson, Theodore Roosevelt, and Abraham Lincoln. Each president was carefully chosen for the role they played in preserving America at any cost.
Construction started in 1927 and over 400 men were hired at $8 an hour pay to do the actual carving. It's interesting to know that all men survived and there were no accidents during construction. These men had to climb up 700 steps daily to get the job done.
Gutzon Borglum designed the sculpture and oversaw the construction in the Black Hills in Keyston, South Dakota.
A ratio of 1:12 was followed for scale. Most of the structure was carved with dynamite! With the explosions, over 450,000 tons of rock were removed from the mountain. Later, each section was carved to appear smooth.
Don't forget that each face was over 60 feet high so workers had to be lowered down from the top of the mountain for drilling using thick steel cables. Each face took several years to complete. The original carving had the presidents up to their waists, but the funding ran out and the monument was declared complete.
