Impress your friends with facts about Mount Rushmore. Many people don’t realize it took 14 years to construct the entire memorial. Construction began on October 4, 1927, and was completed on October 31, 1941.

Sculptor Gutzon Borglum stated, “The purpose of the memorial is to communicate the founding, expansion, preservation, and unification of the United States with colossal statues of Washington, Jefferson, Lincoln, and Theodore Roosevelt.”

Construction began with George Washington, which was dedicated on July 4, 1930. From there, Thomas Jefferson was sculpted and completed in 1936. They dedicated Abraham Lincoln in 1937, followed by Theodore Roosevelt in 1939.

More than 400 workers constructed Mount Rushmore. The work was dangerous and difficult, but jobs were scarce during the Great Depression. Workers had to sit in a sling drilled into the side of the mountain and work with heavy equipment and machinery while suspended in the air.

They also climbed over 700 stairs to reach the top of the mountain and start their day. There were no casualties during Mount Rushmore’s construction.

4. The Mount Rushmore Crew Had a Baseball Team

The men who constructed Mount Rushmore were strong and capable of hard work. They also enjoyed playing baseball on the weekends. Workers with baseball skills were hired, and they eventually formed the Keystone Boys.

The team was good enough to qualify for the South Dakota State Championships and the semifinals.

5. 90% Of Mount Rushmore Was Carved With Dynamite

Dynamite was the main tool used during Mount Rushmore’s construction. They carved 90% of Mount Rushmore with dynamite. Workers used specific measurements to determine the amount of explosives. From there, fine carving created the iconically smooth granite surface. They removed more than 450,000 tons of rock throughout the construction duration.

6. Call Boys Ensured Safety During Construction

Workers on top of the mountain hand-cranked winches to lower and raise the suspended drillers. This was dangerous because of the height and dynamite explosions.

The Mount Rushmore crew hired young men and boys as “call boys.” The young boys sat on the side of the mountain and communicated with the suspended workers and men working at the top to communicate effectively and ensure safety.

7. Each Eye on Mount Rushmore Is 11 Feet Wide

Each eye carved into Mount Rushmore is approximately 11 feet wide to put size into perspective. George Washington’s head is 60 feet tall and the largest among the presidents. His nose is 21 feet tall. Each president’s mouth is about 18 feet wide.

As one of the most recognizable monuments in the world, Mount Rushmore stands at 5,725 feet above sea level.

8. The Honeycombed Granite Was Very Desirable

During construction, the Black Hills’ honeycombed granite was desirable to visitors. Interested visitors often called the hoist operator and inquired about obtaining a piece of the rock. Hoist operators tried to tell visitors the rock was unavailable but would also haggle until they offered $6.00 to purchase the granite.

Selling granite for cash became a pattern. Whenever a visitor bought a piece of granite, workers replaced it with another enticing granite piece for visitors to purchase.

9. The Faces Were Originally Meant To Expand to the Waist

Visionary and sculptor Gutzon Borglum originally planned to include the president’s bodies down to the waists in the Mount Rushmore design. This ultimately didn’t happen due to a lack of federal funding and timing so close to World War II.

The sculptor behind Mount Rushmore, Gutzon Borglum, believed in leaving a legacy for future generations. He began constructing a Hall of Records in 1938 behind the carved heads to preserve information about the mountain and United States historical records. He even hoped the room would hold important artifacts like the Constitution.

Unfortunately, the federal government instructed Borglum to focus construction on the faces. Borglum passed away in 1941 before the faces were finished. His son finished the faces, and the government declared the project officially finished. The Hall of Records still exists but was never completed and is closed to the public.
