Probable cause

Pilot's selection of unsuitable terrain for an off-airport landing and takeoff. The uneven terrain (with a snow berm) was a related factor.

Sequence of events

Analysis

The student pilot and his passenger had landed at a remote Mountain, off-airport landing site to reportedly photograph a bear. During the ensuing take off attempt, the ski equipped Piper PA-11 airplane struck a snow berm with its right main landing gear ski. The right main landing gear collapsed, causing substantial damage to the airframe.
