Observations

Testing the new format.

Was able to look at all aspects today.

I try to get out at the beginning of each storm cycle to see what the snow is falling on. Based on the last couple of weeks, ranging from Big Creek Summit to the 7 Devils, it is a mixed bag. My main concern is on the north aspects which contain weak surface snow and surface hoar with feathers over an inch long in places. Snow pack is thin in all places. I've also seen some weak snow below sun crusts, something to keep in mind as the crusts get buried and degrade (long-term).

Right now my only real current concern is the booby traps in the thin snow, that will change when we get more snow. With enough load I could see a natural cycle on the norths and increasing hazard with the additional load. The free for all may be over later this week if we get foretasted snow amounts.

IF you are reading this, please submit obs when you get out, the PAC needs the info, Thanks!

Soft, shallow cracks in the new snow.

Advanced Observations

Observed Avalanche Problem #1: 
Storm Slab
Comments: 
Not much to the slab but the new snow (HST=2-3") is denser than the underlying snow on northerly aspects, Some cracking, soft, no shooting cracks. I was able to get some weak (q3) shears at the base of the new snow in hand pits. Not really a concern today but more of a warning if the forecast verifies and we get more snow.
Observed Avalanche Problem #2: 
Wind Slab
Comments: 
I was also able to get some cracking in wind drifts, soft, non shooting. The drifts were up to 10" deep.
