Event Details
According to the pilot's account, he was navigating using a WAC (World Aeronautical Chart) at 1:1,000,000 scale rather than the more detailed sectional chart at 1:500,000 scale. He believed he was at a safe altitude for the surrounding terrain. While approaching a saddle on a mountain ridge near the Continental Divide, which he thought was 11,500 feet MSL, he realized he was well below the summit. Surrounding terrain prevented a turn-around, so he applied full power in an attempt to climb above the summit. The aircraft then struck a rock ledge, skidded, and came to rest inverted against an embankment at the 12,200-foot level.
