Yep, and it's even called "Canadian Rockies Geology Road Tours"! It's by Ben Gadd, a geologist who lives in the area and is as funny a writer as he is a good geologist (go to www.bengadd for a bio). Things like a question and answer on "how long will the Rockies last?" or a discussion of "Confusing, amusing toponymy in the Columbia Icefield area."
Don't know if the book is available on Amazon though. I had to order my copy from Alpine Book Peddlers in Canmore, AB (E-mail is alpinebk@aeontech.ca). I paid $28.50 Canadian for it, but it is 576 pages with lots of B&W photos and is arranged by waypoints with mileage (mi and km) for each highway.
Boy, have we hijacked this thread!
