Seeing the iconic faces of past presidents George, Tom, Teddie, and Abe in person, carved onto the face of Mt.Rushmore, is a very moving experience. And it is moving in many ways. Visible in the second image on George’s head are electronic instruments capable of measuring even the slightest movement in three dimensions on the massive heads. These monitors were placed along some of the major fractures in the sculptures which have been sealed with epoxy. To date, no movement of the granite sculpture has been detected. It seems that these sculptures will be here for a long time to come.
