Painting and Nature Preservation: Yellowstone and Landscape Photography
Likewise, landscape photography played an important role in the preservation of other national parks, including Yellowstone.
Photographs by W. H. Jackson of the Hayden geological survey, along with the paintings of Thomas Moran, provided representations of Yellowstone that firmly established the national importance of the geographical region.
Note: Thomas Moran is standing in the picture a little to the right of center for scale, casting a shadow on the rock behind him.
