Thanks Chris. I wonder what temps this is at? Based on two previous trips there at same time of year, it could be a bit below freezing at times - but I plan to go up a little higher, camping at the foot of glaciers etc for part, so the water will be colder.
Like you, I am careful to boil only what's needed. I have a pot cosy but never really used it. Not sure if it's worth it or not, just for one simmer per day.
Re wood, The current wet spell here (it's been horrendous today and getting worse) is making me think hard about actually managing there should the same conditions be found. Bad enough if wet for days, but not having the ability to cook easily could be just horrid! But it could be as it was for the previous trips, almost perfect.
