What a great log of an unimaginable trip for most of us. You certainly peg the risk management meter the entire way. Some trips are hazardous only in mountainous regions or rivers or swamps...because of the extereme cold, you faced danger the entire time! Perhaps you could address how you managed your phone, GPS and any other electronic equipment in the cold. Some phones are stated to not work below -10C by manufacturers. Did you have an on-board charger for them? I don't think you mentioned the manufacturer of your insulated suit that kept you alive all this time. Is there any gear that you are going to buy that you think will do a better job than what you had?Congrats on a job well done. Your perseverance and determination are monumental. Hats off!!
