Book excerpt: When authors Emerson Sanford and Janice Sanford Beck began backpacking together nearly 20 years ago, they often wondered whose footsteps they were retracing and how today's Rockies trails came to be there. In Life of the Trail, they share their findings with hikers and history buffs, adventurers and armchair travellers. Life of the Trail 5 details the routes in the area bounded on the north by Lake Minnewanka and the Bow River and on the west by Altrude Creek and the Vermilion and Kootenay rivers. Featuring such historical characters as Duncan McGillivray, David Thompson, George Simpson, Tom Wilson, Walter Wilcox and Bill Peyto, Volume 5 in this remarkable series also sheds light on the early days of the now world-renowned Kananaskis Country.
