Observations from Corn Biscuit BTL and TL terrain.
Obvious signs of instability
Observer Comments
One potential skier remote in PMS bowl. see photo below. Several large natural's observed on south facing aspects, south of center ridge (probably from direct action cycle 1/23-1/25).
Weather
Winds generally calm to light and temps around -3 to -5. cirrostratus clouds in PM progressing altostratus by later afternoon.
Snow surface
Rain line 520m, very stout rain crust in BTL terrain. Ski pen 10cm at tree line with supportable crust below.
Snowpack
Both 1/21 BSH and 12/25 BSH were found in test pit locations. 1/21 BSH interface was producing mostly resistant results, PST 30/100 Arr, ECTn's moderate strength, and there were 2 sudden results (CTM SC and ECTP Moderate). 12/25 BSH interface produced only one stability test result and that was a ECTN Hard. The 1/21 interface is SH embedded within a melt freeze crust structure (unique Alaskan situation).
