At its going rate, Mount Rushmore erodes only one inch every 10,000 years. Borglum was the work’s sculptor and its first conservator. He and his crew sealed natural cracks in the mountain with a mixture of linseed oil and granite dust. Today, a repair crew on staff at Mount Rushmore patches cracks with a silicone-based caulking material on an annual basis.
Should a manmade or natural disaster ever significantly damage the monument, the park has a 3-D digital scan of the entire mountain, within centimeter accuracy of details, which could be used to recreate it. The data was collected during a two-week laser-scanning project the park administered in 2010, with help from specialists from the Kacyra Family Foundation and Historic Scotland, an agency of the Scottish government charged with protecting historic sites. “The sky is the limit on what kind of visitor programming we can do with this data,” says Bracewell. Soon, the memorial will be able to create virtual fly-bys and trips to the unfinished hall of records and the top of the mountain. Over two million tourists visit Mount Rushmore every year, but, with new tools, such as holographic images for use in classrooms, the National Park Service will be able to share the experience of the memorial with many more.

I've been researching my geneology and I did know my family owned the lumber company that provided scaffolding & etc for the construction of the monument & upon reading this article I also was able to confirm my great great grandfather was the mayor of Rapid City! No wonder I felt at home when I vacationed in South Dakota for the Sturgis Rally. I love this state even more!

My great grandfather is Chris Vranich. He is on the memorial wall and worked on the build of Mount Rushmore. Yesterday I received many photos. Among them are four photos of my grandfather working on Mount Rushmore. Another ten or so photos are of him with his wife and children with the mountain in the background, under progress of being built. Also a few photos of their home at the time, which was located at the base of the mountain. It got me looking around online and these are some wonderful photos shown here also!! Very beautiful.

This is a really good article about the making of Rushmore. Also glad to see the mention of the Lakota opposition to it.
A lot of people forget the Black Hills were sacred ground to the Lakota Sioux. So, it's not surprising they were offended by this shrine to their oppressors.
I wish they'd been able to finish the Hall of Records behind Mount Rushmore. When you read about it, it sounds impressive.

Great information. I remember visiting Mt. Rushmore during a field trip to our Gillette natural gas operations in Wyoming. It was a nice drive. I do hope someday consideration will be given to adding a fourth head to the monument, that of America's first black president and Noble peace laureate, Barack H. Obama.

A very good and very balanced account of the construction of Mt. Rushmore and the surrounding issues is found in Judith StGeorge's book, The Mt. Rushmore Story.

The monument should have been dedicated to Sitting Bull, Tecumseh, Red Cloud, and the other great Native American leaders, who are the true founding fathers.

This was a wonderful article. My family operated the National Park Concession for 40+ years so I had the privelege of growing up at Mt. Rushmore. It will always be home.

Great summary story of the making of Mount Rushmore and the celebration of its 70th. year after completion. Nice piece to add the factual recentment that the Lakoda Indians have/had.

Ann and I stayed below Mount Rushmore in June 2011 for a week. We truly loved every minute that we woke up and looked up at George Washington looking down upon us and the valley. We took hundreds of pictures of Mount Rushmore and the surrounding area. Those four (4) Presidents being above us made us SO proud. Thanks for keeping the area in such a lovely condition for everyone to come see and be proud of America and your area of our country. We WILL BE back in the future to view the area in the future.

Great story, and balanced regarding American Indian views of Mt. Rushmore. My grandmother corresponded with many artists of the time, including Gutzon Borglum.
It was probably gold prospectors panning for gold who invaded, rather than panhandlers.
