This painting features the High Sierras and Mount Lyell, Yosemite's highest peak, as viewed from along the Tuolumne River. Named after Charles Lyell, a friend of Charles Darwin and a noted geologist, the mountain is known for its glacial ice. Keith's painting features a foreground filled with craggy trees, boulders, a slow-moving river, and other picturesque elements. Keith traveled in the area with the naturalist John Muir.
