MacGill Shoulder

Did a quick Test Profile @ 2100m, SE Asp, with a CTM 11 (SP) down ~90cm on SH sz 3mm that was sitting on top of the 2cm thick crust (Jan 17 interface). While putting on my skis at the pit, a punched through with one leg and felt a big whumpf. (Scary!) Test Profile #2 at 2150m, SW asp, CTH (B) on SH down ~70cm. No crust found here. Very good skiing BTL and sheltered TL, ALP/upper TL wind affected.
