Narrative:

Contacted snow drift with left main gear while landing. Aircraft yawed left and slid to a stop against the snow bank on the left side of the runway. Incident happened at dusk with airport runway lights on (one side only) and runway had not been plowed since earlier in the day. I may have misjudged the runway center line and caught the left main gear in deeper snow causing the left yaw. Better runway maintenance and lighting would have helped avert the situation but this is a privately owned public use airport and those of us based there have to accept the risk of operating out of a less than perfect facility. I have operated here without incident for over 7 years in all sorts of limiting but none the less VFR weather situations.
