What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

Approximately 3/4 of a mile down the glacier from camp the aircraft encountered fog at a bend in the glacier, PIC elected to do a slow turn towards the rocks when the aircraft impacted the snow. Aircraft came to rest inverted on the glacier with the cabin mostly intact. PIC was not able to retard the stuck fuel control lever, the fuel shut off was pulled and the main battery switch tuned off. All passengers were able to depart the aircraft on their own except for one who's seatbelt was cut by the PIC.
