Every summer between 1882 and 1929, naturalist William Francis Ganong travelled through the wilderness of New Brunswick, systematically mapping previously uncharted territories, taking photographs, and documenting observations on the physical geography of the province that laid the foundations for the modern study of New Brunswick's rich natural history. In The Lost Wilderness, acclaimed photographer and naturalist Nicholas Guitard retraces many of these journeys, comparing his notes with those recorded by Ganong in handwritten travel journals and published articles and monographs.
