Date of Observation: 02/24/2017
Name: Irwin Guides
Subject: Irwin Tenure
Aspect: East, South, West
Elevation: 10,000-12,000

Avalanches: none.
Weather: OVC skies turned X in the pm with light snow, mostly S -1, with a couple convective waves of heavier snow, light w/ moderate Gusts WSW, minimal snow transport, started increasing late afternoon. Cold temps Highs reached: 12F/0F
Snowpack: Very few signs of instability, with very minor cracking off the ridge in EBM, otherwise no signs of instability. New snow seems to be bonding fairly well to crusts. Double Crust facet sandwich (Feb 22 & Feb 19) on E,S,&SW with facets in-between, could become problematic and will need to be tracked. SBM, Flaming Ferrari/Sunny Shouder (HS 225cm): 15cm’s of new snow on top of 2cm MFcr (Feb 22) then 2-8 cm’s with 1mm Facets to the 25cm MFcr (Feb 19th). Ski pen going through Feb 22 crust in shady areas BUT NOT in Sunny Areas. LWW, Top of D&D (HS 100): 15cm’s of New snow on top of 1cm MFcr (Feb 22) then some .5mm facets before the Feb19 MFcr (6-10 cm’s). 2mm facets below the 19th crust but very rough and uneven. Ski pen going through Feb 22 crust. Lone Wolf had pretty equal distribution of new snow (20cm’s) and not really cross loaded, No Cracking. Minor pockets triggered in cross loaded rollover above LA Fadeaway and in Gerbil Shooter. Thread and Needle blown out up high with double crust. A fair bit of new snow (30cm’s) once you got mid slope. No cracking, minor sluffing.
