On Sept. 20, 1869, Charles W. Cook, the leader of an expedition exploring the Yellowstone area, came upon the Grand Canyon of the Yellowstone River for the first time. He wrote afterward in his journal: “I was riding ahead, the two pack animals following… I remembered seeing what appeared to be an opening in the forest ahead, which I presumed to be a park, or open country. While my attention was attracted by the pack animals, which had stopped to eat grass, my saddle horse suddenly stopped. I turned and looked forward from the brink of the great canyon, at a point just across from what is now called Inspiration Point. I sat there in amazement, while my companions came up, and after that, it seemed to me that it was five minutes before anyone spoke.”
