Fifty Percent of Mountaineering Is Uphill is the enthralling true story of Jasper's Willi Pfisterer, a legend in the field of mountaineering and safety in the Rocky Mountains. For more than thirty years, Willi was an integral part of Jasper's alpine landscape, guiding climbers up to the highest peaks, and rescuing them from perilous situations. Originally from Austria, this mountain man came to Canada in the 1950s to assail the Rockies, and stayed to become an integral part of mountain safety in Western Canada and the Yukon. His daughter, Susanna Pfisterer, has shaped his stories and lectures as an engaging and educational adventure story that features over 100 archival photographs, including avalanches in the National Parks, highlights from climbing 1600 peaks and participating in over 700 rescues, and guiding adventures with Prime Ministers. Accompanied by the humorous wisdom of the "Sidehillgouger", readers will traverse an historical and spectacular terrain.
