Toured from Tamarack TH to the top of Red Cone. We left the car at 1000 and reached the ridge (10,300') a little before 1200. We did not observe any signs of instability while skinning, with the exception of a partially covered D 1.5 avalanche on an isolated 40 degree slope near the summer trail beneath Crystal Lake around 9,400' and the D2 crown in Red Cone Bowl. We skied a lap down the east aspect of Red Cone to ~9,500', staying on largely sub-30 degree slopes. No instabilities were observed.
While skinning back up, we dug a full pit at 10,000' on an east facing, 35 degree slope. HS=180. Thin 1F-4F crusts are present at 85 cm and 130 cm, and the wind crust/slab from yesterday is between 155-165 cm. Stability tests yielded results of CT11 SP @ 130 cm and ECTP12 @ 155 cm.
