Out of interest on the battery front - although you were able to recharge the main battery most nights, for a trek of that length/temperature/photos taken how long do you think a battery would last and roughly how many would be required for the whole trek?

Curious as I plan to do something similar next year and most of the treks I'm looking at would very much be on the no electricity available at all end of things.

Difficult question as I'm not quite sure how to answer. I did charge literally every night except the last few days when I started swapping batteries as I was sure they would last. I think on average a fully charged original battery would last 2-3 days (or 200-300 shots). But whether they deteriorate in the cold without being used I'm not sure.

If I thought I couldn't recharge batteries I would likely bring one per two days of trek, and would take less photos if I thought I was running out. But if I also had to carry all those batteries, then I'd look into solar charging options. Last time I evaluated those none seemed very good though.
