Phantom Ranch is a special destination whether one returns to the South Rim or continues rim-to-rim. It is situated in a deep gorge of the canyon near the confluence of the great Colorado River and Bright Angel Creek. In the early 1970's Bradford Washburn of the Boston Museum of Science collaborated with the National Geographic Society to undertake a modern mapping project of the canyon. He was assisted with field surveying by Barbara Washburn. The canyon was mapped using photogrametry and the emerging GPS (Global Positioning System) technology.
