Gary, during a rockslide I could do a play by play -- sounds like fun!
Actually, although I am not a geologist, I really enjoy trudging through the mountains trying to figure out what we are looking at. My poor wife has been subjected to many years of my monologues, but she never complains.
The Canadian Rockies are especially interesting -- it is like looking at a stop action movie. They started as deep ocean sediments, got thrust up into the sky, and are eroding down under assault by ice and water.
And by the way, now that your legs are back in top shape, I would bet that you could do much of the Iceline Trail near Yoho!
