Park spokeswoman Maureen Oltrogge says the park's communication center began getting calls Saturday afternoon about a man spotted over the edge in an area between Mather Point and Pipe Creek Vista, east of the South Rim Village.
She says rangers rappelled down to the man's body and prepared it for transport out of the canyon via helicopter. His body will be sent to the Coconino County Medical Examiner in Flagstaff.
Oltrogge says the man was visiting the park with his son, daughter-in-law and other family members. His name was not immediately released.
The death is being investigated by the National Park Service.
