Mount Rushmore National Memorial is a national memorial centered on a colossal sculpture carved into the granite face of Mount Rushmore in the Black Hills near Keystone, South Dakota, United States. Completed in 1941 under the direction of Gutzon Borglum and his son Lincoln, the sculpture's roughly 60-ft.-high granite faces depict U.S. presidents George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln.[1]
Coverage
Mount Rushmore is featured in the documentary.
In 10,000 years after people, the most colossal stone structures of man has built still remains. David Brin mentions Mount Rushmore which is carved out of solid granite in an ecologically stable place and the only enemy it has is the wind driven pellets of rain. He thinks that Mount Rushmore may survive for around a hundred thousand years, possibly 200 thousand years or possibly in time to be looked at in awe by the earliest of human replacements. That replacements would be perhaps chimpanzees that perhaps may take the leap.
