Sun and wind have pretty much effected most slopes and aspects that we came across. Alpine north facing was pretty wind effected and the solar aspects were hard and firm in the morning but were softening up by noon.
on a SE aspect at 87000 ft I found 3 different crusts at the top of the snow pack. Top one 3 cm thick then a small 1-2 cm layer of faceted snow then another 3 cm crust. Then 5cm of faceted snow then a 4-5cm crust and then just sugar underneath. When we get more significant snow fall these slopes maybe something to really watch out for on steeper slopes.
