Analysis

The plt had landed the ski equipped acft on the shore of a lake that was covered with grassy tundra & snow. For a subsequent takeoff, he elected to continue straight ahead rather than back taxi to where he had a known surface condition. During the takeoff, the plt elected to lift-off prematurely to minimize bouncing/pounding on the rough surface. However, the skis broke thru the crusted snow & the acft nosed over.
