First published in 1935, Pilgrims of the Wild is Grey Owl's autobiographical account of his transition from successful trapper to preservationist. With his Iroquois wife, Anahereo, Grey Owl set out to protect the environment and the endangered beaver. Powerful in its simplicity, Pilgrims of the Wild tells the story of Grey Owl's life of happy cohabitation with the wild creatures of nature and the healing powers of what he referred to as "the great Northland" of "Over the Hills and Far Away."

A bestseller at the time, Pilgrims of the Wild helped establish Grey Owl's international reputation as a conservationist. His legacy of warnings against the degradations of nature and the dangers of industry live on, despite the posthumous revelation that he wasn't, in fact, the First Nations man he claimed to be.
