Book excerpt: "Life of the Trail" is a fascinating series that guides today's hikers and armchair travelers through the stories of historic routes in the Canadian Rockies. 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 trails through the Rockies came to be there. In "Life of the Trail," they share their findings with adventurers and history buffs alike. "Life of the Trail 4: Historic Hikes in Eastern Jasper National Park" includes trails throughout the Jasper area, as well as routes outside the national park itself. The main routes are fur trade routes, Duncan McGillivray's route along the Brazeau river and Poboktan Creek, Jacques Cardinal's route from Jasper to the North Saskatchewan River along the South Boundary Trail and over Job Pass, and Old Klyne's Trail over Maligne and Cataract Passes and along the Cline River to the Kootenay Plains. The fourth is a 20th-century route: the Skyline Trail.
