Every year about two million people visit Mount Rushmore, where the faces of four U.S. presidents were carved in granite by sculptor Gutzon Borglum and his son, the late lincoln Borglum. The creation of the Mount Rushmore monument took 14 years from 1927 to 1941 and nearly a million dollars.These were times when money was difficult to come by and many people were jobless. To move the more than 400,000 tons of rock, ฺBorglum hired laid off workers from the closed-down mines in the Black Hill area. He taught these men to dynamite, drill, carve, and finish the granite as they were hanging in midair in hid specially devised chair, which had many safety features, Borglum was proud the face that no worker were killed or severely injured during thr years of blasting and carving.
