This upcoming trip reminded me of a Disney movie as a kid. The movie is based on the book BANNER IN THE SKY by James Ramsey Ullman. It is a fictional narrative that follows the first ascent of the Matterhorn, more or less. Filmed in Zermatt and Chamonix, the well travelled climber will recognize that the striking granite means we are in Chamonix and the gneiss means we are back in Zermatt. FYI ... famous French guide Gaston Rebuffat arranged all the climbing scenes.
