As far as mountains go, Mount Rushmore is in a league of its own; not because of steep faces or challenging terrain, but what it represents. A fitting tribute to commemorate US History, work on the monument situated in Keystone, South Dakota began in 1927. Spearheaded by Danish architect Gutzon Borglum and Chief Carver Luigi del Bianco, the four presidents depicted signify different stages of America's growth, which are birth (Washington), growth (Jefferson), development (Lincoln), and preservation (Roosevelt). Like its namesake, the Expedition is built to stand the test of time.
