The 1968 journey to Patagonia by Yvon Chouinard and Doug Tompkins is the stuff of legend, and from it epic tales and giant companies were sparked. Four decades later, Jeff Johnson retraced their travels for Chris Malloy's 2010 film, 180° South, and this companion book documents his journey to the edge of the world. It's part surf trip, part climbing expedition, and part environmental reckoning.
