Park officials say a body -- presumptively identified as Gillies -- was found Saturday morning less than half a mile from the confluence of Bonita Creek and the Colorado River on the North Rim, along with a backpack and personal items.
They say the Coconino County Medical Examiner's Office will try to identify the body and determine the cause of death. Search crews found Gillies' car Wednesday.
Authorities say he started his hike July 18 with plans to come home Monday. Gillies' father called park officials Tuesday when his son failed to return.
