Will the Halloween hoars haunt us in November?

Quite an amazing day for Oct 31st. Lower valley or BTL/upper Treeline snow is non existent. We utilized a side by side to gain access to the snow line. We were able to start touring at 1900m. Large new surface hoar has developed over the last couple days. Up to 10mm in sheltered treeline and 3-4mm in the non solar alpine. -4 deg at 1230hrs with strong solar and no wind. We avoided the tempting southern asp in the area. 105cm of snow at 2150m. 25cm of previous storm snow on top of a strong and supportive crust. 55cm down is another 2cm crust. Mid and lower snowpack are 1f- to 1f. 4mm wet and warm basal facets await you at the ground level. We enjoyed the NE facing alpine and 25cm of cold snow. Great turns for 150m of elevation loss. Some pinwheeling from rocky and steep south facing asp. We found the slippery crust only 10cms down on this aspect. Name of the game is our first major surface hoar layer of 2021/2022. Ride safe folks.
