Lioness and Cubs, Upper Geyser Basin

Thomas Moran's sketch captures a wildlife scene rendered with economical pen strokes across aged paper. The composition layers the landscape in horizontal bands—distant mountains, middle ground terrain, and foreground vegetation—while a lioness and cubs occupy the central rocky formation. Moran's hand moves quickly across the surface, establishing form through contour rather than detail. The notation references Upper Geyser Basin, Yellowstone, suggesting field study from the artist's travels in the American West. This working sketch demonstrates the observational practice underlying Moran's larger landscape paintings, where gestural marks record both topography and fauna encountered during expeditions that shaped nineteenth-century visual documentation of western geography.
