While the first three figures —Washington, Jefferson, and Lincoln— were almost unanimously agreed upon, there was some debate over who should be the fourth face on Mount Rushmore. Gutzon Borglum, the sculptor, advocated for Theodore Roosevelt, but others believed Woodrow Wilson should be included. In the end, Borglum stuck with his original choice, and that's why today we see Teddy Roosevelt up there on America's Shrine of Democracy.

While it's hard to picture the Black Hills without the iconic faces of Washington, Jefferson, Roosevelt, and Lincoln, the original idea for Mount Rushmore was actually quite different. At first, Sculptor Gutzon Borglum envisioned a more complex job (yes, even more complicated than it already is!) In his original plan, he imagined not just the presidents' heads but their upper bodies as well! There was even talk of including other key figures from American history, like explorers Lewis and Clark.

We can assume that carving the giant heads of 4 presidents into the granite was no easy task. But do you know how long it took to complete the monument we see today? 14 years! That's right; 14 years of hard work, 400 men, and a whole lot of dynamite went into bringing this colossal project to life.

As the first President of the United States and widely known as the "Father of His Country," George Washington was a must for this incredible monument. In fact, his face was the first to be completed and was officially dedicated in a grand ceremony. In addition, as part of the powerful symbolism behind the work, Washington's sculpture is also the most prominent.

One of the many unexpected construction challenges involved the placement of Thomas Jefferson's sculpture.

The original plan was to place Jefferson's face to the left of Washington. However, when the dynamiting process began, they found quartz beneath the surface, which made it impossible to continue carving in that spot. After 18 months of work, they "erased" (yes, again, with dynamite) what they had of Jefferson and started over to the right of Washington, where it is today.

Did you know there's a secret room hidden behind the 60-foot-tall heads on Mount Rushmore? The sculptor had big plans for the monument, including a Hall of Records carved into the mountain to store important national documents like the Constitution. And he started to build it! However, when Congress found out that part of the budget was set aside for the Hall of Records, they asked Borglum to focus solely on carving the heads.

After Washington's, the other faces followed: Jefferson's was dedicated second, and Lincoln's was officially unveiled in 1937. So, which one came last? That's right! The last to be completed was Theodore Roosevelt's, with his iconic mustache included! Of course, members of the Roosevelt family attended the big ceremony.

Building Mount Rushmore took many years. Unfortunately, Gutzon Borglum, the mind behind the project, didn't get to see it fully completed, as he passed away just a few months before the work officially ended. However, it was his son Lincoln who stepped in to complete the great work his father had started.

Borglum believed this monument should stand the test of time, built to inspire and be admired for thousands of years to come. So, how did he achieve that? Some historical sources suggest one of Borglum's techniques was adding extra material to certain angled areas of the sculpture, like Washington's nose, for example. That's right! It's believed that the author added an extra foot to George Washington's nose to help it better withstand erosion over time.

Long before the presidents were carved into the Black Hills, a New York lawyer paid a visit to the area, and that visit wouldn't go unnoticed. In 1885, attorney Charles E. Rushmore was at the site for business, and he asked for the name of a particular peak. When they told him it didn't have a name, he jokingly suggested they could call it "Rushmore Peak." Charles E. Rushmore was actually the first person to make a private donation to get the project started: $5,000! And so it was that his name stuck.
