Numerous avalanches Castle Peak

My Guest and i set out from the castle peak Snow park towards frog lake cliff around 10 am today.  During our approach we noticed some small surface hoar formation on sheltered solar aspects and cracks along cornice ridges. We did not note any wind slab formation throughout  the terrain we traveled through all though there were several d2- d3 sized wind slabs that looked like they had failed naturally during the tail end of the 3/14 storm cycle.   We opted to not ski our intended line due to a massive cornice guarding the entrance (east aspect 8500'), the east wind dying down early (warming temps) and having seen cracks along cornices as well as a recent cornice failure on an adjacent slope that had triggered a d2 wind slab. 

We proceeded west from the top of the frog lake cliff along the east ridge of Castle peak- It appeared that every single slope on the north side of castle that could avalanche had- some during the storm with crowns and deposits re buried to varying degrees.  These looked to be average d3 in size, likely wet slabs and ran anywhere R3-R4.  The more recent looking avalanches had deposits that had not been buried by the snow at the tail end of the storm and appeared to be wind slabs some initiated due to cornice failure. These ranged d2-d3 in size.  There was at least one wind slab that had stepped down to a much deeper layer- this deeper crown looked to be 6'-8' in size but didn't propagate to broadly... There was another deeper crown on a more NW aspect that had pulled out below a cliff band.  Both of these slides had some tell tales of a hard slab/ persistent problem, but were too far off to investigate further. 

The largest slide was a wind slab that looked very fresh that had sizable propagation (1000+ wide), failed about 8800'. NE aspect. D3 R4 and ran over the bench nearly to the max runout. 

We noted 2-3mm Surface hoar on near ridge top N aspect 8500'.

The most interesting thing we observed all day was when a pair of snow machines climbed out of the north bowl very near our location- long shooting cracks off of their tracks on the slope they had just climbed moments before.  Unsure if this was just the crust failing but given the size of the cracks my guess would be a weak interface a bit more than the near surface rain crust. Given all the recent avalanche activity we weren't about to down climb onto the slope to investigate further but may be worth a second look at the layering in the zone.
