Snowpit Observations
More detailed information about the snowpack: 

I ventured up red cone towards crystal bowl this afternoon to see how the winds have affected the alpine terrain. The area was largely scoured, I was able to find small pockets of deposited snow on small rollovers or terrain features that encouraged cross loading.  I did note wide spread surface hoar growth (1-3mm) in shaded areas on all aspects and even found sun crust on the surface in isolated areas on southern aspects. 


I dug in at 10,500 ft on an ENE aspect, height of snow was 95 cm air temp was 29° F. My pit showed continued weakening of our shallow snow pack.  Compression tests highlighted a weak layer about 20 cm down underneath a melt freeze crust.  This buried crust seems to be faceting out and becoming less reactive.  Skiing above tree line was quite variable ranging from supportable and breakable wind board, to sastrugi, to pockets of soft snow. Below tree line surface conditions remain pleasant though shallow. Caution is advised, as many preseason obstacles exist.
