Pubblicato negli Stati Uniti nel 1956, 'Il canto selvatico' è il libro più celebre di Sigurd F. Olson, uno dei principali scrittori naturalisti del Ventesimo secolo ed erede ideale di H.D. Thoreau e John Muir. Organizzato seguendo lo scorrere delle stagioni, dalla primavera all'inverno, 'Il canto selvatico' passa in rassegna i grandi e piccoli eventi che scandiscono il passare del tempo in uno degli ultimi luoghi incontaminati del nostro pianeta, la regione del Quetico-Superior, tra Stati Uniti e Canada, un territorio di confine in gran parte selvaggio e quasi del tutto disabitato che Olson ebbe modo di esplorare a piedi, con le ciaspole, sugli sci o a bordo di una canoa. Grazie a una prosa ispirata, quasi poetica, Olson riesce a raggiungere il cuore dei lettori scrivendo di cose tanto semplici quanto magnifiche: i boschi e i laghi gelati, il disgelo e il rifiorire della vita, le lunghe camminate, gli estatici viaggi in canoa, i fuochi degli accampamenti e ancora le trote e i falchi, le oche e i lupi, le tempeste di neve e le aurore boreali. Finora inedito, 'Il canto selvatico' riesce a toccare le corde più sottili degli amanti della natura - un libro pieno di ricordi di cose perdute, ma anche di speranze e di sogni futuri.

Sigurd F. Olson was the most beloved wilderness advocate of his generation. His renowned writings, including the nature classics The Singing Wilderness and Listening Point, evoke the singular beauty and richness of the northern woods and lakes and reveal a philosophy of preservation that is as eloquent and relevant today as when he first wrote. The wilderness was the spring of happiness in Olson's life, and he devoted himself to the pursuit of sharing this magic with others and ensuring its future existence.Revealing Olson's understanding and love of wilderness, Spirit of the North gathers together for the first time the most quotable and memorable of his well-loved passages gleaned not only from published works, but also from personal letters, journal entries, and speeches. Reflective, anecdotal, and universally poignant, this book is a chronology of thoughts and experiences that ebb and flow in their assuredness and reveal the whole man, a wilderness icon mired in doubt while he doggedly refused to abandon his dreams. David Backes, preeminent Olson biographer and scholar, contributes an introduction to each chapter, illuminating the historical context and personal significance of Olson's words.Frequently, during a quiet moment of contemplation on a canoe trip, Olson would read brief passages of poetry and prose scrawled on small scraps of paper for inspiration and peace of mind. Similarly, Spirit of the North is the ideal wilderness companion, passionate, authentic, and deeply reverent of the natural world.Sigurd F. Olson (1899-1982) introduced generations of Americans to the importance of wilderness through his work as a conservation activist and popular writer. He served as president of the Wilderness Society and the National Parks Association and as a consultant to the federal government on wilderness preservation and ecological problems. He earned many honors, including the highest possible from the Sierra Club, the National Wildlife Federation, and the Izaak Walton League.David Backes is the author of A Wilderness Within: The Life of Sigurd F. Olson (Minnesota, 1997), winner of the 1998 Small Press Book Award for biography, and editor of The Meaning of Wilderness: Essential Articles and Speeches by Sigurd F. Olson (Minnesota, 2001). Backes is also the author of Canoe Country: An Embattled Wilderness (1991) and The Wilderness Companion (1992).
