Widespread natural cycle on middle elevation north facing buried surface hoar. New snow from 1/9 was punchy and upside down. Did not observe wind slabs along ridges and instabilities seemed confined to mid elevation north aspects where surface hoar had been preserved. This layer has the potential to be a Persistent Weak Layer.
Clear skies in the morning gave way to overcast clouds mid morning preserving the solar aspects from forming a temperature crust.

Middle elevation north aspects with buried surface hoar.
Did not dig a pit. All instabilities were related to new snow from 1/9.
Layer Depth/Date: 12 inches
Very touchy conditions. Remotely triggered from above at one point.
Skinning up the south aspect, we did not have any collapsing but noticed the punchy snow. Scanning the upper elevation slopes, we did not see any signs of avalanches or much wind affected terrain. Ski cuts in mid elevation north aspects produced predictable storm slab avalanches on steeper roll overs. We noticed a widespread natural cycle in wind sheltered terrain that held buried surface hoar. Skinning back out, we remotely triggered more slides and used micro terrain features to safely return to the ridge and off the north aspect. Quality surfy skiing on a southern aspects.Close
