Generally followed the summer Snow Lake trail until the fork between Source/Snow Lakes, then turned up towards Snow Lake with our sites set on the top of the ridge just south of the lake. Shortly after, we left the established trail and headed left to cut our own more direct route up the steep slope (through the trees mainly) to attain the ridge. We caught up with the established trail once again below the cliffs in order to get around them (visibility was poor since we were mostly in the clouds)

Weather: Low clouds, temperatures near freezing in the lower elevations. Moderate winds (seemingly) out of the South and much colder up on the ridge.
Snowpack: The snow seemed well-packed and stable for the most part. I saw a few pinwheels on the bare slopes in the lower elevations that looked a week old or so, so they didn't bother me too much. On the lower elevations (S-facing aspects) there was a lot of evidence of snow breaking off and rolling down the hill from some of the small cliffs above the trail, but nothing that seemed to propagate as it headed downhill (smaller-than-snowball-sized debris chunks scattered about on the surface of the snowpack)
Area Description: Lower elevations of the Snow Lake trail, traversing the slopes on the SW side of Snoqualmie Mountain, this past SATURDAY (1/9)
Avalanches: On the way back down towards the end of the day, there was evidence of a very small slab avalanche (~4" slab, but it was also very wide) about a mile from the trailhead, maybe 50 yards above the trail. It did not travel far since the slope was quite shallow (estimating 20-25*). It did not cross the trail. I'm guessing it may have been initiated by tree bomb(s) since it was getting quite warm in the low elevations by 3-4pm. Be careful out there guys. Avalanche danger is low out there but it can still happen. This trail was very busy this past weekend. I was glad to see some people turning around due to their own skill/comfort levels with conditions.
