Tens of thousands of visitors have enjoyed a Grand Canyon sunset from Hopi Point on the canyon's south rim. 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.
