View from tunnel on Iron Mountain Road - Mount Rushmore National Memorial, SD. The federal government paid $836,000 of the nearly $990,000 cost of the monument. A good investment considering the millions of tax dollars generated yearly from tourism. Though the state of South Dakota did not appropriate any funds for the actual creation of the monument, it spent huge sums of money on highways and advertising.Photo: Russ Finley Film Size 6X7cm
