Rainbow over the Grand Canyon of the Yellowstone

Thomas Moran's 'Rainbow over the Grand Canyon of the Yellowstone' (1900) returns to the subject that had launched his career three decades earlier — the monumental western landscapes of Yellowstone that had helped convince Congress to establish America's first national park in 1872. Moran's original Yellowstone paintings had been purchased by the government and displayed in the Capitol building, making him the visual chronicler of America's natural wonders and an architect of the national park idea. This late canvas in the Smithsonian's collection demonstrates his continued engagement with a subject whose grandeur had defined his artistic identity.

Moran orchestrates the Yellowstone canyon's dramatic scale through a deep recession from foreground cliffs through the canyon depth to distant peaks. The rainbow provides a luminous arc of colour that unifies the composition and gives the sky its dramatic role alongside the geological spectacle below. His warm palette of ochres, oranges, and purples captures the canyon's characteristic colour in the specific quality of western light.
