The NTSB's narrative final · quoted from the NTSB record
The pilot stated the passenger talked him into flying up a canyon, which appeared to be a pass at the time they entered. Once inside the canyon, the pilot realized there was insufficient room to complete a 180 degree turn. He applied full power and attempted to climb straight ahead. After reaching about 2,800 feet above sea level, the airplane's floats struck the ground. The airplane slide approximately 15 feet, then nosed over.
