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 the Life of the Trail series, they share their findings with hikers and history buffs, adventurers and armchair travellers. Life of the Trail 6 details historic routes in the area north of the Columbia Icefields and south of the Miette River, bordered on the east by the Athabasca and Sunwapta rivers (today's highway 93). Along with the mythical Mounts Hooker and Brown, readers will come across historical character David Thompson, A.P. Coleman, Hudson's Bay Company Governor Sir George Simpson and Group of Seven painters Lawren Harris and A.Y. Jackson.
