Problem #1 Comments: 

Really no Wind slab, Storm Slab, or Loose dry noted.  Did not see signs of any today.  I will say that with the sun comming out tomorrow I am worries about wet loose and wet slab on all solar aspects failing as deep as 1 meter on the 2/20 rain crust.

I honestly went out today in search of something that Evelyn spurred.  I was wondering if with the warm up on south aspects tomorrow or Thursday, if aspects that formed a melt freeze crust on Sunday Feb 26th would have more slab characteristics when the new snow warmed up.  So I went to see if I could get the melt freeze crust to fail on the low density snow from Sat 2/25 or within the crust.  What I found was on true South aspects the melt freeze crust was stout enough that in Compression and ECT's I could not get it to fail but it did fail on shovel shear.  On More SE aspects the crust was thinner and I hoped would fail in a slab on an ECT but to no avail.  I did get failure on CT's though.  Maybe if the new snow warms up enough to form a slab we could see something but at this point I highly doubt it.  

What I am worried about is Wet loose entraining a lot of snow as it heats up over the next day or two.  Such low density snow getting a shock will be interesting.  There is so much snow (up to a meter of settled snow) sitting on the super stout rain crusts from 2/10 and 2/20.

On the note of storm slab.  I do not think I was ever in terrain today that was steep enough for the storm slabs I triggered yesterday.  Non of the test slopes were close to 35 degrees.  So that is most likely the reason.  

As for the wind slabs I was able to trigger a few but so small even in very loaded terrain.  Up to 4 in deep at the deepest.  These were also Fist hardness.  Both of these characteristics of the wind slab surprised me.  I did expect a lot more of a slab.

Moderate for everything.  Maybe Considerable for Wet loose at all elevation SSE-SW???

Depending on what others saw POCKETS of Considerable Wind Slab on E-N upper elevation ridges.
