Watercolor by Thomas Moran entitled, "Lower Entrance to Madison Canyon, August 8, 1871 (Yellowstone)
Thomas Moran (1837-1926) was one of the outstanding American artists of the nineteenth century. He left a legacy of works that define the western landscape. He concentrated on depicting scenery of what is now several western national parks including Yellowstone, Grand Canyon, Devils Tower, Yosemite and the Grand Tetons. He also traveled with Ferdinand Hayden's 1871 geological survey of the Upper Yellowstone and documented many sites along the way with his sketches and watercolors. Thomas Moran's daughter, Ruth Moran, donated a large collection of her father's works including oil paintings, etchings, black and white washes, pencil sketches, diaries, photographs and personal items to Yosemite National Park in 1935.
