Snowpack
Most slopes that we traveled on produced spider web cracks across the entire slope. We were mostly targeting W, SW, and SE slopes for feedback: these were all reactive under snowmobiles.
Avalanche
Near and below treeline slopes produced a widespread cycle of soft slab avalanches breaking on the January weak layer; these all appeared to run last night and this morning. We had limited visibility of alpine terrain. Slides were generally D1 to D1.5, with a few D2s in larger terrain; slabs were typically 30 to 50 cm; larger with elevation up valley. Avalanches occurred on nearly all aspects; the most extensive activity was on E and NE slopes (mostly due to terrain biases), with a significant amount of activity on SE, SW, and W aspects. We remotely triggered a handful of avalanches on near treeline slopes as well. Remotely triggered an avalanche cycle in South Baldy Bowl from ~1,500 feet away to the nearest avalanche. ~2,500ft to the furthest avalanche. Measured on Google Earth. Basically, one avalanche ran and that likely sympathetically triggered 3 others. Up to D2 . Poor visibility and I couldn't see the whole production as it was happening. Those crowns spanned from 11,800ft to 12,200ft on SE to S aspects.
