I have often heard that stress can make your hair turn gray, and many before and after photos of American presidents seem to prove the point. I cannot imagine how terrified the father in your story would have been as he realized that he, and his child, would be in an avalanche. This event certainly would cause a traumatic response in the body. Including this story in your post made your pictures and the information about this monument so much more personal. I can relate to the emotion surrounding the location, and see the people who drive this pass with more empathy. Thank you for sharing @irvet 🌱
