The Stoney Indians called him Nashan-esen meaning "wolverine-go-quick" because of his speed in travelling on snowshoes over the rugged landscape of the Canadian Rockies. This book is the story of Jimmy Simpson's 80-year epic as one of the most important guides, outfitters, lodge operators, hunters, naturalists and artists in the Canadian Rockies. The story takes him from blazing the trails in the valley bottoms to ascending some of the highest peaks in the range, from leading scientists, mountaineers, big-game hunters and world-famous artists through some of the most unimaginable scenery on earth to entertaining thousands of visitors at his famous lodge at Bow Lake with his tales-both true and tall-of the pioneer days.
