Red Flags Comment
<p>Persistent weak layer was prevalent on upper-elevation northerly slopes </p>

Excellent day of riding upper elevation low angle slopes. Riding was particularly good in sheltered areas protected from recent wind event. Average snow depth was 80cm. Persistent weak layer was identified at approximately 59cm down in the snow pack, approximately 10-20cm from the ground, consisting of 2-4mm facets. standardized compression tests produced results of CTV, and CT16, and Extended Column Test ECTP16, indicating that the persistent weak layer is still very reactive.
