The black-and-white picture above is a detail of a photo taken by S. C. Walker in 1877, and reused by James M. Hutchings in his In the Heart of the Sierras (1886). See also a high-resolution version from the Yosemite Nature Notes (1977). (Walker also took a photo of Anderson at Dome's other overhanging rock, with Tenaya Canyon in the background). The colored picture was taken by the author from the same place, almost 130 years later, in 2006.
