GRAND CANYON, Ariz.  – On Saturday, August 28, at approximately 4:19 p.m., the Grand Canyon Regional Communications Center received a report of an injured non-commercial river trip participant in the Deer Creek Narrows within Grand Canyon National Park. The participant fell approximately 50 feet while on a hike in the narrows and could not be located by members of the river trip. 

Multiple teams of National Park Service (NPS) technical and swiftwater rescuers were flown into the site the evening of August 28; however, due to terrain, darkness, and safety concerns they were unable to locate the individual.

On Sunday, August 29, NPS personnel located the individual, David Colburn, 48, of Tygh Valley, Oregon. Colburn was found deceased and recovered by rescue personnel and was transported via helicopter to the South Rim. An investigation into the incident is being conducted by the NPS and the Coconino County Medical Examiner's Office.
