Ahead of the festivities, here’s what you need to know about the national monument.

What is Mount Rushmore?

The monument shows the faces of U.S. presidents George Washington, Thomas Jefferson, Teddy Roosevelt and Abraham Lincoln. Their images were built out of the side of a mountain in the Black Hills in South Dakota.

Each face is 60 feet tall, with 21-foot-tall noses, 11-foot-wide eyes and 18-foot-wide mouths, according to Business Insider.

How much did Mount Rushmore cost to build?

According to Business Insider, Mount Rushmore originally cost $989,992 to build -- which would be more than $17 million today, adjusted for inflation, according to the website.

The project -- which employed about 400 people and used dynamite to blast away 450,000 tons of rock -- took 14 years, according to History.com.

The website reported that in 1991, the monument was restored in 1991 for $40 million.

That money “supported 2,140 jobs in the area and had a cumulative benefit of $177 million to the local economy,” the report said.

Is Mount Rushmore controversial?

According to Business Insider, the Black Hills -- where Mount Rushmore was created -- are sacred to the Lakota Sioux Native American tribe. The tribe strongly opposed the project when it was started in the 1920s and today, tribal leaders are still calling for the sculpture’s removal, The Hill reported.
