Two centuries ago, the idea of preserving nature, rather than exploiting it, was a novel one to many U.S. settlers. One of the turning points in public support for land conservation efforts — and recognizing the magnificence of the Yellowstone region in particular — came in the form of vivid photographs.
This year marks the 150th anniversary of a series of Yellowstone National Park photos by the renowned landscape photographer William Henry Jackson. He captured the first-ever shots of iconic landmarks such as the Tetons, Old Faithful and the Colorado Rockies.
Jackson snapped them on a late 19th-century expedition through the Yellowstone Basin that was conducted by the head of the U.S. Geological and Geographical Survey of the Territories, Ferdinand V. Hayden. The team included a meteorologist, a zoologist, a mineralogist, and an agricultural statistician.
