How Old Is That Mountain? is about the Rockies. More specifically it's about the Rocky Mountains of Banff and Yoho National Parks and adjacent areas. It's about thrust faults and glaciers, hot springs, carbonate and shale. And time. Vast amounts of time.

Intended for those who don't know a graptolite from a j�kulhlaup, How Old Is That Mountain? conveys the most current understanding of how these mountains came to be, keeping geological jargon to a minimum. Yorath distills reports, scientific papers and the work of other geologists into a fascinating and readable account for anyone who is interested in their natural surroundings and has ever wondered "how old is that mountain?"

Illustrated with more than 60 photographs, maps and diagrams, How Old Is That Mountain? is also an excellent field guide, offering visitors a new understanding of this popular tourist destination. Taking the reader along the Trans-Canada Highway from the Mountain Front to the Rocky Mountain Trench and from Lake Louise to the Columbia Icefields, Yorath presents a fresh and intriguing look at the geology of this incredible region.
