The pilot reported that he aligned the airplane on final approach with what "appeared" to be the runway with a small snow berm on both the left and right sides.
The pilot further reported that the left main landing gear touched down first, and then the airplane came to an "abrupt" stop a few feet to the right of the runway.
A postaccident examination of the airframe reviled substantial damage to the right wing.
The pilot reported that there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
