Did you see shooting cracks?
NoDid you experience collapsing or whumpfing?
Yes, IsolatedObservations
In open north facing ridge (no trees) at 4,500 ft, snow layer was significantly thicker (~1 foot) and wet and was consolidating easily into layers that seemed easy to slide on the icy layer underneath. When crossing a 35 degree slope, roller balls the size of large beach balls rolled down effortlessly.
Small isolated collapsing was also observed nearby on flat surfaces (less than one foot radius underneath skis).
