We are more than one. We are both public and private. Granite. We are one of natures many natural beauties, but we are indeed special. It is not cheap to visit here. Although unique and special we are not that well known internationally. We are not Mt. Rushmore in South Dakota, USA. We are not located in the USA. And, it never snows where we are. Turquoise is a prominent color here. The highest elevation here is less than 500 meters. A famous Explorer climbed to the top of this summit to make a decision. In the 19th Century a tragic event occurred here that spawned a Folk Heroine in our region. There have been many famous Visitors here: Prince Charles of England. What am I or what are we?
