The NTSB's narrative final · quoted from the NTSB record

THE PILOT REPORTED THAT HE OVERFLEW THE RUNWAY TO TRY TO DETERMINE THE DEPTH OF THE SNOW ON THE RUNWAY. THE PILOT SAW TIRE TRACKS NEXT TO THE RUNWAY AND THOUGHT THAT THE DEPTH WAS ABOUT TWO INCHES. THE PILOT INITIATED AN APPROACH FOR A LANDING. DURING THE LANDING ROLL, THE NOSE WHEEL DUG INTO THE SNOW AND THE AIRPLANE NOSED OVER. IT WAS LATER DETERMINED THAT THE SNOW WAS FIVE INCHES DEEP WITH A CRUSTY TOP LAYER. THE AIRPORT/FACILITY DIRECTORY STATES THAT THE AIRPORT WAS CLOSED AT THE TIME OF THE ACCIDENT.
