'In these sixteen photographs are many deep echoes of experience from more than forty years in Yosemite Valley. Each represents, for me, a moment of wonder. The pictures are put together as a continual pattern of personal mood and response...The collection is, in a way, a personal autobiography in photographic images, the selection of which is based on emotional impulse and personal experience rather than on intellectual or historical judgement.' (Ansel Adams, foreword to Portfolio Three)
