The pilot was landing a wheel-equipped airplane on a remote, snow-covered, seasonal airstrip. When the airplane touched down, the nose gear broke through the five-to-six inches of crusted snow on the runway and the airplane nosed over. The airplane sustained substantial damage to the vertical stabilizer and wings. The pilot reported no pre-accident mechanical failures or malfunctions with the airplane. The FAA Airport/Facility Directory entry for the airport notes the airport is unattended and closed from October 1 through June 1 each year.
