We rode to the Wilderness boundary near Astral Lake and skied a small loop through to Green Lake. We then rode across to Lulu and Daisy Passes to look for avalanches. We saw several wet loose slides on south faces. We saw no new deep slab avalanches since Alex was there last week. After a late start due to some sled issues, we dug one pit looking for new upper level weak layers. ECTNs on hardness changes. We did not note any new persistent weak layers.
While it remains possible to trigger very large avalanches on persistent weak layers near the base of the snow pack, it is clearly becoming less likely. Unfortunately, if you triggered one, it would be no less deadly.

On 3/10/24 Low on Daisy Road along the steep creek walls we saw three recent 2' deep avalanches. each 70-100' wide. HS-R4-D2-O. One looked within the last day or two and the other two were maybe 3-4 days old. Triggers unknown, there were various ages of sled/snowbike tracks nearby.
On 3/10/24 Between Miller and Wolverine there was a recent large avalanche that I would guess was triggered yesterday. 3-6' deep, 250-300' wide. HS-R4-D2.5-O. Video and photos attached.
