Comments
AST1 Course Obs: Arrived at 5 mile with heavy snowfall and high S.winds through the pass. HST = 35cm. Skinned up to 800m, with ski pen 30cm, easy hand shears and shooting cracks on HST. High S. winds and significant snow transport crossloading entire area. We had numerous settlements and remote triggering of Sz 0.5 in low angle, supported simple terrain. The higher we climbed, the stiffer the slab due to winds.
Test Profile: 720m, W aspect, S-4, shows a fairly well consolidated snowpack with numerous crusts. 35-45cm of HST overlies a MfCr? which was bonding poorly. ECTP2 down 35 on DF 1.5, CTE4, 5 down 35 on DF 1.5. HS of 240cm.
Heavy snowfall made the trip back eventful!
