Mount Rushmore National Memorial is a sculpture carved into the granite face of Mount Rushmore near Keystone, South Dakota, in the United States. Sculpted by Gutzon Borglum and later by his son Lincoln Borglum, Mount Rushmore features 60-foot (18 m) sculptures of the heads of former United States presidents (in order from left to right) George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln. The entire memorial covers 1,278.45 acres (5.17 km2) and is 5,725 feet (1,745 m) above sea level. It is first seen in "Rollercoaster" when Phineas and Ferb's ride is pulled away from its tracks, and spins around in Teddy Roosevelt's glasses.
- Mount Rushmore appears to be close to Danville, as the Flynn-Fletcher family arrived there quickly on Candace's birthday.
