Ansel Adams’s interest in photographing nature led him to a lifelong relationship with one of the largest and most influential environmental organizations: The Sierra Club. David Ackerman, an executive committee member of the Sierra Club’s Ohio Chapter, will detail how this mutually beneficial relationship came to be, and how we all have benefited from it.
