Nice photos....
what is the temperature rating of your bag? were you warm enough?
I use a 10 degree bag I sleep warm and get hot quick. I do recommend 2 sleeping pads, sleeping directly on snow/ice can get cold quick.
I only took one sleeping pad to save space and wish I brought the roll up foam pad for an extra layer..
temps were in the 30 to 40 during the day and as cold as 10 at night!
