- Porter was drawn to the Galápagos Islands, a small and remote
group of islands along the equator off the coast of Ecuador. Fascinated
by the islands’ unique and diverse ecology and their historical
significance as the foundation of Charles Darwin’s theory of
evolution, he traveled there in 1966.
- He photographed close-ups of the islands’ varied animal species,
plants, and terrain.
- Porter wanted to create a photographic book to make people aware
of the need to protect the islands. The idea appealed to Sierra Club
Executive Director David Brower, who was interested in starting an
Earth National Park conservation campaign. In 1968 the Sierra Club
published Porter’s island portrait Galápagos: The
Flow of Wildness.
