This series, written by climbers for climbers, condenses vital information and advice on how to climb the seven summits into a new pocket format. Each spiral-bound and waterproof book weighs only 4 oz and features full-color photographs, diagrams, a wrap-around map flap and step-by-step detail on each route. Aconcagua, one of the world's highest and toughest treks, is surprisingly free of snow and ice, and experienced hikers can reach the roof of the Americas without technical expertise. Kikstra explains in detail how to tackle both the Normal and Polish Traverse routes.
