The NTSB's narrative final · quoted from the NTSB record
According to the pilot, he and the passenger were spotting for elk. He located some elk and maneuvered the airplane to put the elk on the passenger's side (right side) of the airplane. This resulted in the airplane flying up a box canyon. As the terrain rose, the pilot realized the airplane would not be able to climb over the ridge at the head of the canyon. He turned to the left and attempted to exit the canyon; however, the airplane impacted the terrain and nosed over.
