Date and time of observation:
Fri, 01/18/2019 - 12:00
Whumphing noises, shooting cracks, or collapsing
Recent loading by new snow, wind, or rain
Density inversion in new snow, medium shear at about a depth of 8”, Lower glove on shear plane, Q2. Upper glove shows thickness of upper denser snow.
Rime crust, formed during a freezing fog event at about 1pm. Real subtle, had to use a bare hand to feel it. Got covered quickly by pellets, some of which are visible.
Cornices are sensitive but are still just breaking the width of the ski used to kick them, no reaction below except for minor sluffing.
Also of note: I tried to isolate pole columns of the new snow on a protected east aspect at 7,400’. I was not able to, this may be the one area I travelled through today that might have had surface hoar.
I poked and podded many areas while walking the ridge to Sargents with no results except for 2 minor collapse with whumping, the new snow seemed to be behaving more than I expected.
My guess on hazard in these areas is moderate, but please note I did not travel through any north facing terrain and would assume a considerable hazard as forecasted today due to the potential for surface hoar. New snow as forecasted would bump my guess to considerable for all terrain if we get significant amounts.
