Book excerpt: Trekking the Continental Divide from the U.S. border to Kakwa Lake is a demanding adventure. In this revised and updated guidebook devoted to Canada's 1,200-kilometre Great Divide Trail (GDT), Dustin Lynx helps hikers piece together the myriad individual routes that form a continuous trail along the Divide. Outlining the six major sections of the GDT, Lynx breaks the trail into shorter, more attainable segments and thoroughly describes the terrain and condition of each. Not only are these trail segments invaluable for planning shorter trips along the GDT, Lynx's pre-trip planning advice will also prove indispensable for long-distance hikers overcoming such daunting logistical challenges as resupply, navigation and access.
