Still there were some extensive views available to passengers in the Sierras, the most famous of which was that from “Cape Horn” http://cprr.org/Museum/Sierra_Grade_8-2003/Cape_Horn/index.html just above the town of Colfax where the grade was carved out of the side of a mountain, providing a panoramic view across Green Valley of the American River flowing in a canyon some 1322 feet below.
