Weather Comments
Porter Fork, particularly in the lower sections where I traveled was not all that windy compared to higher, more exposed locations. There were periodic strong gusts that were swirling around a bit. The trail head was also very warm - about 40F when I started.

Snow Characteristics Comments
Recent warm temps left a made for a mix of relatively poor surface conditions. At higher elevations, the crust was annoying but skiable. At lower elevations, the snow was very wet and thin.

Recent Avalanches
Heavy Snowfall
Wind Loading
Rapid Warming
Red Flags Comments
Recent loose snow avalanches from maybe yesterday were observed on west facing slopes and possibly a larger slide on the Porter Rock slabs, although visibility was limited. At lower elevations, the snow was quite wet and warm.

Decreasing Danger
Problem #1 Comments
Dense snow and high winds were creating some new wind slabs that were visually obvious. It seemed like these were distributed inconsistently, probably reflecting the erratic winds in this location. On one small windloaded roll, no significant cracking was noted.

Decreasing Danger
Problem #2 Comments
As noted in other observations, two density changes could be observed in the upper part of the snow pack. One of these produced easy shears 10 cms down.

Comments
This pit was in a similar location to one from December 23rd. Facets are still there with slightly improved hardness. The mid pack is now much thicker and stronger - in December there wasn't much snow above the facets. Your pole would easily push through to them.
Note: Danger rating below reflects where I traveled - below about 8000 feet and not on windy ridges. I'm sure things would be more touchy in those locations.
